E2B is a fast-growing Series A startup with over $37M in funding and 8-figure revenue. We are building the Agent Cloud and power the infrastructure behind AI labs and some of the most widely used consumer and enterprise agents, including Manus, Genspark, Lindy, ClickUp, Groq, and Artificial Analysis. Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.
You will be building the next cloud platform for running AI software - a cloud where AI apps are building other software apps.
Your job will be:
Building a distributed system for millions and billions of AI agents running on E2B
Building an orchestrator for placing sandboxes in the right nodes
Adding support for sandbox live migrations
Making sure our self-hosting DX is as smooth as possible (we’re open-source)
Not letting our sandboxes take more than 200ms to start (starting with the user hitting enter)
Scaling to millions and later billions of sandboxes running at the same time
Building an observability stack starting at the kernel level of virtual machines
We’re looking for an infrastructure engineer passionate about making things run fast and efficiently, and running A LOT of them at the same time.
If you aren’t afraid of going into the kernel of a VM and words like Firecracker, eBPF, UFFD, block device, L4 load balancing, noisy neighbor problem, or hugepages sound exciting to you, we want to hear from you!
5+ years building distributed systems - You've operated infrastructure at serious scale (100K+ RPS, multi-region, PB-scale data) and understand the trade-offs between consistency, availability, and partition tolerance in practice, not just theory
Deep Linux internals expertise - You're comfortable working at the kernel level. You've debugged performance issues using eBPF, understand CPU scheduling, memory management, and can explain the difference between cgroups v1 and v2 without looking it up
VM hypervisor experience - You've worked with Firecracker, QEMU, KVM, or similar. You understand virtio, know what a hypercall is, and have opinions about nested virtualization trade-offs
Systems programming skills - Strong in at least one of: Go, Rust, C/C++. You've written performance-critical code and know when to reach for lock-free data structures, memory-mapped files, or io_uring
Production orchestration experience - You've built or operated orchestration systems (Kubernetes, Nomad, or custom). You understand bin-packing algorithms, resource scheduling, and have dealt with noisy neighbor problems at scale
Performance obsession - You've shaved milliseconds off hot paths, understand CPU caches and memory locality, and have profiled production systems under load. You know what \"p99 latency\" means and care deeply about making it better
Networking expertise - Strong understanding of L4/L7 load balancing, network namespaces, iptables/nftables, and how to build secure, isolated network topologies for multi-tenant systems
Located in San Francisco or willing to relocate - We work in person as a team and believe in the magic that happens when engineers collaborate face-to-face on hard problems
Excited about open source - Comfortable with our code and infrastructure being public. You contribute to discussions, write clear documentation, and help the community succeed with self-hosting
Experience with userfaultfd (UFFD), copy-on-write mechanisms, or lazy loading
GPU passthrough or PCIe device virtualization experience
Built or maintained infrastructure for AI/ML workloads
Contributions to Firecracker, Cloud Hypervisor, or similar open source projects
Experience with observability at scale (distributed tracing, kernel-level metrics)
We’re a fast-growing startup with in-person (4 days on-site, 1 day WFH) offices in San Francisco and Prague, Czech Republic. We already generate 8-figure revenue and work directly with top-tier AI companies like Manus, Genspark, Lindy, ClickUp, Groq, Artificial Analysis and other exciting teams pushing the frontier of AI.
We offer healthcare, vision, and dental insurance, unlimited PTO, 401k, and a variety of perks for in-office employees.

Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.
ABOUT E2B
E2B is a fast-growing Series A startup with 8-figure revenue. We've raised over $37M since our founding in 2023. Our customers include companies like Microsoft, Perplexity, Hugging Face, Manus, and Groq. We're building the next hyperscaler for AI agents.
ABOUT THE ROLE
This is the first business operations leadership hire at E2B. The company has scaled from $1M to 8-figure ARR in under a year, raised a Series A, and is now preparing for the next stage of growth.
You'll own everything that isn't engineering, GTM, or design. Finance ops until our Head of Finance lands. Legal admin and contracts. People ops and onboarding. Office logistics across San Francisco and Prague. Vendor management. The internal tools that make the company run.
This is a hands-on role for the first 6 to 12 months. You will personally run payroll, negotiate the office lease renewal, and fix the broken Notion. As the company grows, this becomes a COO-track role with a real team underneath you.
You'll partner directly with Vasek (CEO) and Tomas (Head of Engineering).
WHAT YOU'LL DO
- Build the operating cadence. Weekly leadership rituals, monthly board prep, quarterly planning. Today these happen ad-hoc. You make them repeatable.
- Run people ops end-to-end. Offers, onboarding, payroll across US and EU entities, benefits administration, equity grants, performance review process, offboarding. Partner with Talent on recruiting ops where the recruiting machine spills into HR (offers, references, background checks, work authorization).
- Own legal admin. Customer contracts, vendor agreements, NDAs, contractor MSAs for our EU hires. You won't be drafting from scratch, but you'll be the person turning around redlines, managing outside counsel, and keeping the contract tracker honest.
- Run office and team logistics. Two offices, two countries, two payroll regimes, occasional team offsites, equipment provisioning, real estate decisions. The boring infrastructure that lets engineers ship.
- Own vendor and tool sprawl. Every SaaS bill, every renewal, every \"do we still use this?\" question. Procurement, security review, cost optimization.
- Set up the bench. As scope grows past one person, you'll hire your replacements: an HR/people lead, a finance hire, eventually a head of legal. You'll define those roles and run those searches.
WHAT WE'RE LOOKING FOR
- 6+ years in operations, with at least 2-3 years operating at a Series A or Series B startup that scaled headcount through 30 to 100. You've watched a company double in size and you know what breaks.
- Generalist DNA. You're comfortable owning finance one week, legal the next, and rewriting the offer letter template on a Friday night. You don't need a defined function to be effective.
- Strong with numbers. Comfortable in spreadsheets, can read a P&L, can model headcount and burn. You don't need a CPA, but you should not need to hand the model off to be useful.
- Real ownership track record. You've personally built or rebuilt at least two of: a payroll process, an offers / equity process, a contracts pipeline, a close cycle, a board reporting cadence, a vendor management process. Not \"managed a team that did\", but actually built.
- Operates at the speed of engineering. We ship fast. Operations needs to keep up.
- Excited to work in person from San Francisco. You'll be sitting next to our CEO and the leadership team.
NICE-TO-HAVE
- Prior chief-of-staff role at a venture-backed B2B startup.
- Experience operating across US and EU entities, including the realities of EU contractor models, GDPR, and entity setup.
- Experience scaling people ops and recruiting ops together. We're hiring fast and the two functions touch constantly.
- Background in B2B SaaS finance, especially with usage-based revenue.
- Ex-consulting (Bain / McKinsey / BCG) is fine if you've spent the years since actually operating, not just running reports.
We’re a fast-growing startup with in-person (4 days on-site, 1 day WFH) offices in San Francisco and Prague, Czech Republic.

Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.
You will be building the next cloud platform for running AI software - a cloud where AI apps are building other software apps.
Your job will be:
Building a distributed system for millions and billions of AI agents running on E2B
Building an orchestrator for placing sandboxes in the right nodes
Adding support for sandbox live migrations
Making sure our self-hosting DX is as smooth as possible (we’re open-source)
Not letting our sandboxes take more than 200ms to start (starting with the user hitting enter)
Scaling to millions and later billions of sandboxes running at the same time
Building an observability stack starting at the kernel level of virtual machines
We’re looking for an infrastructure engineer passionate about making things run fast and efficiently, and running A LOT of them at the same time.
If you aren’t afraid of going into the kernel of a VM and words like Firecracker, eBPF, UFFD, block device, L4 load balancing, noisy neighbor problem, or hugepages sound exciting to you, we want to hear from you!
5+ years building distributed systems - You've operated infrastructure at serious scale (100K+ RPS, multi-region, PB-scale data) and understand the trade-offs between consistency, availability, and partition tolerance in practice, not just theory
Deep Linux internals expertise - You're comfortable working at the kernel level. You've debugged performance issues using eBPF, understand CPU scheduling, memory management, and can explain the difference between cgroups v1 and v2 without looking it up
VM hypervisor experience - You've worked with Firecracker, QEMU, KVM, or similar. You understand virtio, know what a hypercall is, and have opinions about nested virtualization trade-offs
Systems programming skills - Strong in at least one of: Go, Rust, C/C++. You've written performance-critical code and know when to reach for lock-free data structures, memory-mapped files, or io_uring
Production orchestration experience - You've built or operated orchestration systems (Kubernetes, Nomad, or custom). You understand bin-packing algorithms, resource scheduling, and have dealt with noisy neighbor problems at scale
Performance obsession - You've shaved milliseconds off hot paths, understand CPU caches and memory locality, and have profiled production systems under load. You know what \"p99 latency\" means and care deeply about making it better
Networking expertise - Strong understanding of L4/L7 load balancing, network namespaces, iptables/nftables, and how to build secure, isolated network topologies for multi-tenant systems
Excited about open source - Comfortable with our code and infrastructure being public. You contribute to discussions, write clear documentation, and help the community succeed with self-hosting
Experience with userfaultfd (UFFD), copy-on-write mechanisms, or lazy loading
GPU passthrough or PCIe device virtualization experience
Built or maintained infrastructure for AI/ML workloads
Contributions to Firecracker, Cloud Hypervisor, or similar open source projects
Experience with observability at scale (distributed tracing, kernel-level metrics)
We’re a fast-growing startup with in-person (4 days on-site, 1 day WFH) offices in San Francisco and Prague, Czech Republic.

Our team includes original authors of Firecracker, the AWS microVM technology powering Lambda, along with alumni of Cognition, JetBrains, Zapier, and Wish.
Your job will be to own and scale the backend that powers the E2B Dashboard and SDK — the APIs, data, and services developers rely on to run, monitor, and debug their sandboxes. You're the backend counterpart to our dashboard engineers: they own the experience, you own the services and data behind it, and together you ship product end-to-end.
This is product/application backend - APIs, data layer, auth, billing, usage metrics, real-time log/metric pipelines. It is not our low-level infrastructure (Firecracker, orchestration, the sandbox runtime) - that lives with our Core and Platform teams, who you'll integrate with but not duplicate.
The split is roughly 80% Go backend, 20% TypeScript — you live in Go, but you're comfortable dropping into the Next.js app to wire things up end-to-end and unblock the frontend rather than throwing work over a wall.
You'll build enterprise-grade services that scale to 100k+ weekly active users. Responsibilities include:
Owning the Go services behind the dashboard and SDK — APIs, data models, and the contracts the frontend builds on
Designing auth/authorization, billing, and usage-metering surfaces
Building the real-time backends (WebSockets, SSE) that feed sandbox logs and metrics to the dashboard
Optimizing data access and server-side performance — query design, caching, response times
Partnering closely with dashboard engineers to ship features end-to-end, and with Core/Platform on the boundaries where product meets infrastructure
Making architectural decisions around observability, testing, and security best practices
This role requires a high amount of ownership and the ability to take projects from 0 to 1. You'll have deep autonomy to make backend and product decisions. If you see a better way to build something, you build it.
3-5+ years shipping production backend services, with deep expertise in Go
Strong API design — REST/RPC, contracts, versioning, and an eye for the interface the frontend actually needs
Solid with PostgreSQL: schema design, query optimization, migrations, and reasoning about data at scale
Backend fundamentals: authentication/authorization, server-side performance, and building real-time data flows (WebSockets, SSE)
Working TypeScript(Next.js is a plus) competence — you won't live here, but you can move into the app-router frontend to wire up a feature end-to-end and not be lost
Understand data fetching patterns on frontend side
Excited to work in person from Prague on a devtool product
Ownership mentality: you see projects through from conception to launch to iteration
Comfortable talking to customers and explaining technical tradeoffs
Not being afraid to take ownership of your part of the product
Great communication, curiosity, and interest in the AI space
If you join E2B, you'll get a lot of freedom. We expect you to be proactive and take ownership. You'll be taking projects from 0 to 1 with the support of the rest of the team.
