Who we are

E2B is a fast growing Series A startup with 7-figure revenue. We’ve raised over $32M in total since our funding in 2023 and are supported by great investors like Insight Partners. Our customers are companies like Perplexity, Hugging Face, Manus, or Groq. We’re building the next hyperscaler for AI agents.

About the role

Your job will be to secure the infrastructure where billions of AI agents execute untrusted code daily. You’ll be responsible for protecting companies’ most sensitive AI workflows while maintaining our sub‑200ms performance standards.

You’ll be building defense‑in‑depth security for our Firecracker microVM infrastructure, implementing real‑time threat detection across tens of thousands of concurrent sandboxes, and ensuring compliance with enterprise security requirements.

This role requires deep technical expertise in systems security and the ability to solve novel security challenges in the AI agent execution space.

What we’re looking for

• 5+ years of experience in production security infrastructure

• Being comfortable with securing distributed systems at massive scale

• Deep expertise in Linux security primitives (seccomp, eBPF, namespaces)

• Excited to work in person from San Francisco on cutting‑edge AI infrastructure

• Experience with container security and microVM hardening

• Track record with compliance frameworks (SOC 2, ISO 27001, GDPR)

• Not being afraid to implement kernel‑level security controls

• If you join E2B, you’ll get a lot of freedom. We expect you to be proactive and take ownership. You’ll be securing infrastructure that protects millions of AI agents with the support of the rest of the team.
