Staff Software Engineer (Agentic Engineering)

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 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

• (Tacos? If you need an ice-breaker, ask how we say thanks by giving tacos!)
• 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.

Our use of AI in hiring

We use AI tools to help manage our recruitment process efficiently and fairly. Specifically:

• Ashby helps us review inbound applications by surfacing candidates who best match the role requirements we've defined. This tool does not make hiring decisions; it helps our team prioritize which applications to review first.
• Granola takes notes during our interview calls so our team can focus on the conversation with you.

All hiring decisions are made by humans. Our team reviews applications, conducts interviews, and makes final selections. AI tools assist us but never replace human judgment, and these practices are conducted in compliance with applicable data protection, AI governance, and labor laws. Your data is not used to train AI models.

In accordance with New York City Local Law 144, an independent bias audit has been conducted on "Automated Employment Decision Tools"; results are available for Ashby.

If you're applying for a role at Coder and have questions about how we use AI in our process, or if you'd like to request information about the data we collect, please contact careers@coder.com.
