Senior Software Engineer, Developer Experience

Responsibilities

• Build the platforms behind agentic developer workflows: roll out the tools the org builds on (Claude Code, Codex, Cursor) and ship the skills, plugins, and MCP servers that run across them.
• Design and build the product surfaces engineers and AI agents reach for daily: self-service workflows in our Backstage developer portal, our developer CLI, IDE integrations, and the framework engineers use to build and deploy their own agents.
• Own and evolve our Cloud Development Environment (CDE) platform for both human developers and AI agents.
• Improve the build systems, CI/CD pipelines, test infrastructure, and observability the whole org depends on.
• Prototype and evaluate new AI developer tools as they land, and decide what to adopt, configure, and scale across the engineering org.
• In order to be successful, you must bring
• Demonstrated experience building developer infrastructure, DevEx, or platform tools that other engineers depend on, from CDE rollouts and internal CLIs to MCP servers and build/CI at 100+ engineer scale.
• Strong systems thinking: you reason about build pipelines, CI/CD, dev environments, and test infrastructure as interconnected systems, not isolated tools.
• A UX mindset applied to engineering systems: you think in personas, journeys, and end-to-end workflows, and design for the people and agents who use what you build.
• Hands-on experience with agentic developer tools like Claude Code, Cursor, or Codex, and considered opinions about their limits, where they help, and how to scale their use.
