Full-time

Coder

What you’ll do here

  • Extend our provider-agnostic architecture as models and capabilities change.

  • Lead complex projects from early ambiguity through production.

  • Raise the engineering bar through design reviews, code reviews, and technical mentorship.

  • Partner with Product and Design on clear, useful agent experiences.

  • Improve the reliability, performance, and operability of agentic systems.

What we’re looking for

  • Deep experience building and operating production software systems.

  • Strong hands-on experience with Go .

  • Experience with React and TypeScript .

  • Hands-on experience building systems around LLMs and agentic workflows.

  • Experience with model APIs, tool calling, context management, or agent loops.

  • Strong distributed systems knowledge.

  • Working knowledge of AWS .

  • A track record of setting technical direction without formal authority.

  • Strong architectural judgment and comfort working through ambiguity.

  • Someone who makes the engineers around them better.

Our tech stack

  • Infrastructure: AWS , Kubernetes

  • Observability: Prometheus , Grafana

Bonus tacos if you have
