Staff Software Engineer - Agentic Engineering

What you’ll do here

• Set technical direction across Coder’s agent harness, integrations, and workflows.

• Design and build production systems in Go, with work across React and TypeScript where needed.

• Evolve agent execution, tool use, context management, streaming, and long-running workflows.

• 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

• Backend: Go, Postgres

• Frontend: TypeScript, React

• Infrastructure: AWS, Kubernetes

• Observability: Prometheus, Grafana

• CI/CD: GitHub Actions

Bonus tacos if you have

• Experience building coding agents, developer tools, or cloud development environments.

• Experience with agent tools, or multi-agent systems.

• Experience building abstractions across multiple model providers.

• Deep experience with AWS, Kubernetes, Docker and Linux.

• Open-source contributions or experience working directly with customers.

Coder’s agentic architecture is provider-agnostic. The foundation is already built; this role helps decide how it evolves, where we invest, and how we keep it reliable as the space moves quickly.
