We provide the control infrastructure that allows government and regulated enterprise to put frontier-class AI to work safely.
\nWe are bringing a frontier AI experience inside secure boundaries for the first time. Our technology supports mission critical workflows across government, healthcare, and enterprise, including:
\nScaling open-weight models without external inference endpoints.
\nPutting frontier class AI to work across organisations through partnerships with other leading AI startups such as Perplexity.
\nIncreasing operational resiliency for air gapped, on prem, and cloud based systems.
\nSecuring intellectual property and maintaining auditability for high stakes enterprise environments.
\nFacilitating secure information flow during disaster response, M&A due diligence, and privileged legal communications.
\nWe’ve only scratched the surface. Built in Britain by veterans of the Ministry of Defence, British Forces, Darktrace, and elite engineering backgrounds, we are driven by a shared mission to safeguard western democracy . Whether you join our London HQ or our wider global organisation, you’ll be part of a collaborative, high performing team creating the cutting edge software and infrastructure that defines the frontier of enterprise AI.
\nThe Role\nWe are looking for an experienced Senior MLOps / LLMOps Engineer to lead the deployment, monitoring, orchestration, and operational reliability of our production LLM applications and agentic AI platform. In this role, you will bridge the gap between AI development and production infrastructure, ensuring multi-step agentic workflows, data pipelines, and retrieval-augmented systems run reliably, securely, and at scale within a large-scale Kubernetes environment.
\nWhat you’ll do:\nDesign, deploy, and manage LLM services, agentic applications, and supporting AI workloads inside high-throughput Kubernetes clusters.
\nAutomate containerized deployments, scalable inference endpoints, and blue/green or canary rollout strategies for LLM/Agent releases via modern CI/CD pipelines.
\nSupport and maintain the production operation of agentic AI workflows, including multi-step tool execution, state management, and multi-agent coordination.
\nRapidly triage and resolve issues across AI application logic, orchestration frameworks, external API integrations, and underlying cloud infrastructure.
\nBuild end-to-end monitoring and evaluation (Eval) frameworks to measure and maintain AI output accuracy, drift, latency, cost, and hallucination metrics.
\nImplement trace-level observability for agent execution paths (tracking prompts, completions, tool calls, and agent steps).
\nMonitor and optimize real-time and batch data pipelines powering AI workloads, including feature stores, vector indexing, and embedding updates.
\nManage resource allocation (GPU/CPU utilization), memory footprint, autoscaling strategies, and cloud infrastructure expenditure to optimize time-to-first-token (TTFT) and throughput.
\nWhat we are looking for: \n3+ years of experience in MLOps, LLMOps, Platform Engineering, AI Infrastructure, or SRE with a focus on machine learning workloads.
\nHands-on experience managing and deploying complex containerized applications on Kubernetes (EKS, GKE, AKS, or bare metal) at scale.
\nStrong proficiency in Python for backend automation, system debugging, custom tooling, and integration development.
\nProven experience with standard monitoring/logging tools (e.g., Prometheus, Grafana, Datadog, OpenTelemetry) as well as LLM-specific tracing and evaluation platforms (e.g., LangSmith, Phoenix/Arize, Langfuse, TruLens).

\nYou will write production Go, build React frontend components, configure microservices, and orchestrate Kubernetes workloads while collaborating across frontend, core backend, infrastructure, and AI teams to deliver client outcomes.
\nWhat you’ll do:
\nWhat we are looking for:
\nGo & Backend Engineering: Strong hands-on experience building microservices, REST/gRPC APIs, or event-driven backend systems in Go.
\nKubernetes Application Logic & Tech Stack: Deep familiarity with Docker, K8s manifests, Helm charts, GitOps workflows (Argo/Flux), relational databases (RDBs), KV Caches, and Event Buses, focusing on building applications for Kubernetes.
\nProduct & Customer Intuition: Demonstrated experience interfacing with external clients, solutions architects, or cross-functional teams to solve real operational problems.
\nSystem Design & Security Boundaries: Clear understanding of workload isolation, secrets management, identity-aware communication, and failure domain boundaries.
\nPragmatic Ownership: Comfort operating in ambiguous, fast-moving environments where debugging spans client applications, networking layers, and platform code.
