The multiplayer control plane for your software factory. Backed by Y Combinator.
About the role
At HumanLayer, we’re on a mission to change how teams build software with AI. If we had a motto it would be “no vibes allowed” - we believe that AI agent-enabled coding is a deeply technical engineering craft , and we’re building CodeLayer to unlock it at scale. A Stanford study from June 2025 said AI can’t solve hard problems or work well in complex or legacy codebases, and we’re proving them wrong with advanced techniques inspired by Context Engineering (a term originally coined by our CEO Dex in April 2025).
What they're looking for
- Work across the entire stack - frontend apps, backend services, native executables, infrastructure, CI
- Have deep experience building in the Typescript ecosystem. We use it across the entire stack - frontend, backend, native executables, infrastructure-as-code
- Ship like an engineer, think like a product owner. You have deep empathy for users and are dedicated to creating a world-class user experience
- Strong in CS fundamentals - operating systems, networking, data structures
- You’re a 99th-percentile Claude Code or Codex user
- You know Postgres/MySQL like the back of your hand
