Staff Software Engineer

As a Staff Software Engineer on Coder's Agentic Engineering team, you'll shape the systems behind our agentic development experience. You'll work across the agent harness, integrations, and workflows that connect agents with real development environments.

You'll stay hands-on while setting the team's technical direction. You'll lead complex work, make sound architectural decisions, and help other engineers do their best work.

What you'll do

• 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.
