Build and scale the platform that runs AI coding agents in isolated, ephemeral environments: sandboxing, resource limits, observability, access control. Coding. Build internal services, APIs, and tooling in Go or Python, with tests and code review. Linux fundamentals. Strong systems administration, performance troubleshooting, and container internals. Security and reliability. Partner with security and SRE to embed guardrails into the platform. Lead and mentor. Drive technical reviews, set standards, coach junior engineers. Product mindset and stakeholders. Translate requirements from product, security, and infra teams into shipped solutions. Focus on developer experience, adoption, and measurable impact. Communicate trade-offs clearly to technical and non-technical audiences. What Essential Skills You Will Need Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience. 5+ years of hands-on experience in platform engineering, infrastructure, or DevOps, with a track record of independently delivering complex projects. Comfortable working in a geographically distributed team. Nice to Have Running AI coding agents or LLM-backed tooling in production (sandboxing, model gateways, cost and token controls).
