\n
Valarian Technologies is a dual-use technology company building critical tools to safeguard the future in an era of evolving global security challenges. We're rethinking security beyond traditional military domains, addressing asymmetric threats that impact our technological advantage, economic strength, and democratic institutions.
\nWe build Acra – the platform foundation for everything we do as a dual-use technology company. The platform’s name, rooted in the Greek word for citadel (or, fortress), reflects the design and purpose of our infrastructure-agnostic secure enclaves: protecting critical data. Some of the government and commercial workflows include: increased operational resiliency for mission-critical systems and functions; enabling organisations to more quickly and widely adopt emerging technologies while ensuring the integrity of their intellectual property; information flow during disaster response scenarios, and zero-trust / least-privilege environments for M&A, attorney-client privileged communications, etc. And we’ve only scratched the surface.
\nAt our core, we're driven by a shared mission and a belief in making a tangible impact on our world. Whether you join our London HQ or the wider global organisation, you’ll be a part of collaborative, high-performing teams, creating cutting-edge software, platforms, and infrastructure.
\nThe Role
\nAs an AI Harness Engineer at Valarian, you will own the experimental design, evaluation methodologies, and benchmark infrastructure for our AI models and autonomous agentic workloads. In an emerging domain with no standard playbook, you will serve as the bridge between rigorous data science, statistical validation, and production agent scaffolding.
\nYou will design robust evaluation datasets, architect calibrated LLM-as-a-judge pipelines, and build metrics that accurately capture multi-step agent performance under non-deterministic conditions. Your insights and error analyses will directly drive iterative improvements to our harness scaffolding, tool orchestration, and system safety guardrails.
\nWhat you’ll do:
\n\n- \n
Architect Evaluation Runtimes & Harnesses: Design and maintain scalable Python evaluation harnesses that measure task completion, trajectory quality, tool-use correctness, cost, latency, and variance across multi-step agentic systems.
\n \n- \n
Design Experiments & Validate Results: Apply rigorous statistical methods—including hypothesis testing, confidence intervals, bootstrapping, and power analysis—to determine whether performance changes are true system improvements or stochastic noise.
\n \n- \n
Build & Calibrate LLM-as-a-Judge Pipelines: Develop automated judging systems validated against human ground truth. Measure alignment using agreement metrics (Cohen’s kappa, correlation, precision/recall) and systematically detect judge failure modes such as position bias, verbosity bias, self-preference, and prompt sensitivity.
\n \n- \n
Curate Benchmark Datasets & Rubrics: Define sampling strategies, detailed annotation guidelines, and scoring rubrics. Measure inter-annotator agreement and manage label noise to ensure benchmark integrity over time.
\n \n- \n
Deep Error & Trajectory Analysis: Conduct hands-on failure analysis on agent runs, cluster root causes into actionable error categories, and clearly communicate findings to both engineering teams and stakeholders.
\n \n- \n
Drive Harness Scaffolding Iteration: Translate evaluation results directly into architectural improvements across agent scaffolding, prompt design, tool execution loops, context window compaction, retries, and safety guardrails.
\n \n
\nWhat we are looking for:
\n\n- \n
Grounding in Statistics & Experimental Design: Demonstrated expertise in hypothesis testing, bootstrapping, power analysis, and statistical significance within probabilistic machine learning systems.
\n \n- \n
LLM-as-a-Judge Validation: Proven experience building, auditing, and validating LLM judge setups against human annotations, including tracking agreement metrics and mitigating judge biases.
\n \n- \n
Evaluation Dataset Engineering: Strong track record designing evaluation datasets, crafting precise scoring rubrics, managing label noise, and measuring inter-annotator agreement.
\n \n- \n
Evaluation of Non-Deterministic Multi-Step Systems: Deep comfort evaluating complex agent trajectories, tool execution sequences, latency, cost, and variance across repeated runs rather than relying solely on single-shot benchmarks.
\n \n- \n
Metric Design & Integrity: Exceptional judgment in defining metrics tied to real-world outcomes, with a keen eye for detecting benchmark gaming, target drift, or shortcut learning.
\n \n- \n
Rigor in Error Analysis: Ability to dissect complex execution logs, categorize failure modes, and synthesize clear, data-driven recommendations.
\n \n
\n\n- \n
Hands-On LLM Integration: Practical proficiency with LLM APIs, prompt engineering, structured outputs, function/tool calling, and retrieval systems in Python.
\n \n- \n
Agent Architecture Awareness: Clear understanding of planning loops, tool orchestration, memory management, and multi-agent coordination, including their trade-offs and common failure modes.
\n \n- \n
Harness & Scaffolding Contribution: Ability to write clean, maintainable Python code to iterate on harness components such as guardrails, retry logic, state handling, and context management.
\n \n
\nNice to have:
\n\n- \n
Experience with agent and evaluation frameworks (e.g., LangChain, LangGraph, AutoGen, lm-evaluation-harness, Promptfoo, or Ragas).
\n \n- Exposure to running evaluation pipelines or agent workloads within secure, enclave, or Kubernetes environments.

Some of the government and commercial workflows include: increased operational resiliency for mission-critical systems and functions; enabling organisations to more quickly and widely adopt emerging technologies while ensuring the integrity of their intellectual property; information flow during disaster response scenarios, and zero-trust / least-privilege environments for M&A, attorney-client privileged communications, etc. And we’ve only scratched the surface.
\n
\n
At our core, we're driven by a shared mission and a belief in making a tangible impact on our world. Whether you join our London HQ or the wider global organisation, you’ll be a part of collaborative, high-performing teams, creating cutting-edge software, platforms, and infrastructure.
\n
\n\n\n
We are looking for a Senior Infrastructure Engineer to own and evolve the foundational infrastructure layer behind ACRA.
\n
This is a deep infrastructure role. You will work across Kubernetes, Linux, networking, storage, service-to-service communication, observability, security boundaries, and production operations. You will be responsible for the systems that everything else depends on: clusters, networks, storage layers, ingress and egress paths, runtime infrastructure, deployment foundations, and operational reliability.
\n
Infrastructure is part of the product at Valarian. ACRA only works if the underlying infrastructure is secure, observable, debuggable, resilient, and able to run across cloud, on-premise, bare-metal, sovereign, air-gapped, and customer-managed environments.
\n
We are looking for someone with strong judgement and real production experience. This role values depth, operational correctness, and careful decision-making. You should be comfortable going deep into complex operational problems, understanding failure modes, debugging under pressure, and improving the reliability of the whole platform.
\n
You should be comfortable operating close to the metal: debugging Kubernetes, understanding networking behaviour, reasoning about distributed storage, improving observability, and helping define the infrastructure patterns that ACRA will rely on as it scales.
\n
This is not a generic DevOps support role, cloud administration role, or internal IT role. You will be a critical engineer in the team responsible for the infrastructure foundations of a high-trust platform.
\n

Contribute to incident response, root-cause analysis, capacity planning, disaster recovery, and production readiness.
\n \n- \n
Define infrastructure standards, operational boundaries, security controls, and deployment patterns across the platform.
\n \n- \n
Work closely with engineering teams to make services easier to deploy, operate, monitor, and debug.
\n \n- \n
Contribute to the long-term technical direction of the DevOps department and the infrastructure foundations of ACRA.
\n \n
\n
\n
What we are looking for:
\n
\n
\n
\n- \n
Strong experience in infrastructure engineering, platform engineering, DevOps, SRE, or production systems engineering.
\n \n- \n
Deep hands-on experience operating Kubernetes in production.
\n \n- \n
Strong understanding of Linux systems, containers, networking, storage, and distributed infrastructure.
\n \n- \n
Strong networking fundamentals, including TCP/IP, DNS, TLS, routing, load balancing, ingress, egress, network policy, and service discovery.
\n \n- \n
Experience debugging difficult infrastructure issues across clusters, nodes, pods, networks, storage, and workloads.
\n \n- \n
Experience with Kubernetes networking, CNI, service mesh, network policy, or secure service-to-service communication.
\n \n- \n

\n
The Role
You will lead the operational, delivery, and governance execution for Valarian’s platform engineering team, acting as the primary operational partner to the Head of Engineering. This role sits at the intersection of technical execution, Product and platform security for ACRA, our complex security-focused Kubernetes platform.
\n
You will own the operational lifecycle of external engineering dependencies end to end: from scoping, scheduling, and managing third-party penetration testing to overseeing contractor budgets, statement of work (SOW) execution, and project billing. You will keep engineering operations financially sorted, compliant, and friction-free, ensuring that external technical deliverables align seamlessly with internal platform engineering cycles.
You will serve as the crucial interface between engineering leadership and external partners. You will translate complex security, infrastructure, and operational requirements into actionable engineering priorities, triaging pentest findings, managing vulnerability remediation workflows with engineers, and reporting clear status, risk, and spend metrics directly to the Head of Engineering.
\nThis is not a role for someone who only wants to manage spreadsheets or pass messages. We are looking for someone who understands the technical product vision, challenges assumptions, and turns complex operational challenges into smooth, reliable systems.
\nAs Valarian grows, this role offers a clear path to increasing operational ownership and strategic influence. We are looking for strong operational judgement, curiosity, ownership, technical fluency, and the ability to bring order to complex environments.
What you’ll do:
\n
\n- Own the Platform Security & Trust Roadmap: Define and prioritize the product capabilities, compliance requirements, and technical enhancements needed to maintain ACRA’s zero-trust security architecture and enterprise readiness.
\n- Define Technical Requirements & Specifications: Translate pentest findings, compliance mandates (e.g., ISO 27001, SOC 2), and technical specs into clear user stories, acceptance criteria, and API contracts for engineering.
\n- Lead Backlog Grooming & Vulnerability Prioritization: Drive product discovery and backlog refinement with engineering, prioritizing vulnerability remediations alongside new feature delivery based on risk, severity, and customer SLAs.
\n- Orchestrate External Security Engagements: Scope and run external penetration tests and third-party security audits as structured product validation cycles, tracking findings through to re-testing and delivery.
\n- Manage External Technical Dependencies: Align third-party integrations, vendor deliverables, and partner APIs with core platform release cycles to ensure unblocked delivery.
\n- Balance Feature Velocity against Technical Risk: Partner with engineering, product, and leadership to evaluate trade-offs between delivery speed, engineering effort, financial costs, and platform security boundaries.
\n- Track Security & Product Metrics: Monitor key product health indicators—including time-to-remediation, security posture compliance, vendor SLA performance, and feature delivery predictability.
\n- Drive Product-Led Security Value: Act as a product owner in a fast-paced startup, ensuring platform security, data sovereignty, and auditability serve as key competitive differentiators for Valarian.
\n
\n
Nice to have:
\n\n
\n- Experience in secure or regulated environments, such as defence, government, fintech, critical infrastructure, or sovereign cloud.
\n- Understanding of zero-trust architecture, identity-aware systems, policy enforcement, or workload isolation concepts.
\n- Experience managing technical delivery in a high-growth startup or scale-up environment.

Some of the government and commercial workflows include: increased operational resiliency for mission-critical systems and functions; enabling organisations to more quickly and widely adopt emerging technologies while ensuring the integrity of their intellectual property; information flow during disaster response scenarios, and zero-trust / least-privilege environments for M&A, attorney-client privileged communications, etc. And we’ve only scratched the surface.\n \nAt our core, we're driven by a shared mission and a belief in making a tangible impact on our world. Whether you join our London HQ or the wider global organisation, you’ll be a part of collaborative, high-performing teams, creating cutting-edge software, platforms, and infrastructure.\n\n\nThe Role\nYou will lead the operational, delivery, and governance execution for Valarian’s platform engineering team, acting as the primary operational partner to the Head of Engineering. This role sits at the intersection of technical execution, Product and platform security for ACRA, our complex security-focused Kubernetes platform.\n\nYou will own the operational lifecycle of external engineering dependencies end to end: from scoping, scheduling, and managing third-party penetration testing to overseeing contractor budgets, statement of work (SOW) execution, and project billing. You will keep engineering operations financially sorted, compliant, and friction-free, ensuring that external technical deliverables align seamlessly with internal platform engineering cycles.\n\nYou will serve as the crucial interface between engineering leadership and external partners. You will translate complex security, infrastructure, and operational requirements into actionable engineering priorities, triaging pentest findings, managing vulnerability remediation workflows with engineers, and reporting clear status, risk, and spend metrics directly to the Head of Engineering.\nThis is not a role for someone who only wants to manage spreadsheets or pass messages. We are looking for someone who understands the technical product vision, challenges assumptions, and turns complex operational challenges into smooth, reliable systems.\nAs Valarian grows, this role offers a clear path to increasing operational ownership and strategic influence. We are looking for strong operational judgement, curiosity, ownership, technical fluency, and the ability to bring order to complex environments.\n\n\nWhat you’ll do:\nOwn the Platform Security & Trust Roadmap: Define and prioritize the product capabilities, compliance requirements, and technical enhancements needed to maintain ACRA’s zero-trust security architecture and enterprise readiness.\n\nDefine Technical Requirements & Specifications: Translate pentest findings, compliance mandates (e.g., ISO 27001, SOC 2), and technical specs into clear user stories, acceptance criteria, and API contracts for engineering.\n\nLead Backlog Grooming & Vulnerability Prioritization: Drive product discovery and backlog refinement with engineering, prioritizing vulnerability remediations alongside new feature delivery based on risk, severity, and customer SLAs.\n\nOrchestrate External Security Engagements: Scope and run external penetration tests and third-party security audits as structured product validation cycles, tracking findings through to re-testing and delivery.\n\nManage External Technical Dependencies: Align third-party integrations, vendor deliverables, and partner APIs with core platform release cycles to ensure unblocked delivery.\n\nBalance Feature Velocity against Technical Risk: Partner with engineering, product, and leadership to evaluate trade-offs between delivery speed, engineering effort, financial costs, and platform security boundaries.\n\nTrack Security & Product Metrics: Monitor key product health indicators—including time-to-remediation, security posture compliance, vendor SLA performance, and feature delivery predictability.\n\nDrive Product-Led Security Value: Act as a product owner in a fast-paced startup, ensuring platform security, data sovereignty, and auditability serve as key competitive differentiators for Valarian.\n\n\nNice to have: \nExperience in secure or regulated environments, such as defence, government, fintech, critical infrastructure, or sovereign cloud.\nUnderstanding of zero-trust architecture, identity-aware systems, policy enforcement, or workload isolation concepts.\nExperience managing technical delivery in a high-growth startup or scale-up environment.\nAgain: these are not requirements. They are areas you may get to work with and go deeper into at Valarian.\n \nBenefits:\n \nOur benefits are designed to ensure our employees feel taken care of and are proud to be a part of the Valarian team. We are committed to consistently enhancing our benefit package, taking into account the overall well-being and needs of our teammates. Here are the key benefits accessible to all employees at Valarian Technologies:\n \nEquity – because you have the right to own what you’re building\nA competitive salary – because we value your unique skills\nEmployer pension contributions – because you deserve a secure future\nPrivate health insurance - because your health is important to us \nHybrid work setup – because everyone has different needs\nRewarding company retreats and meetups that respect your work/life balance – because we love getting to know each other!\nLife at Valarian\nOur culture is built on inclusivity, compassion and flexibility – we want everyone to be empowered to achieve their goals at Valarian.\n \nThe work we do is vital, but so are the connections that make it happen. We thrive on the shared energy, spontaneous conversations, and mutual trust built when we spend time together. We operate on a hybrid model, gathering in our London office 3 days a week to support one another and collaborate. \n \nWe may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information.
