Software Engineer (Builder Tools)

• As a Software Engineer on the Builder Tools team, you will build and maintain the CI/CD infrastructure, internal tooling, and AI-assisted development workflows that every engineering team at Hadrian depends on
• Your users are Hadrian’s engineers, and your job is to make them faster
• That means owning shared pipeline libraries, reducing friction in the SDLC, making internal systems accessible to AI coding agents, and automating the work that slows teams down
• The systems you build touch every engineer at Hadrian, and the improvements you ship show up immediately in how fast the company moves
• Build and maintain CI/CD pipeline libraries that abstract build, release, and deployment events for use across multiple engineering teams
• Design and build internal tools, APIs, and CLI utilities that reduce developer friction and automate recurring engineering tasks — dependency upgrades, credential rotation, routine maintenance
• Help make Hadrian’s internal systems API-ready for AI coding agents; build harness tooling, context systems, and feedback loops that improve the quality of AI-generated contributions in our codebase
• Instrument and monitor developer productivity systems; surface bottlenecks and measure the impact of tooling improvements through clear metrics
• Partner with application development teams to identify needs, implement CI/CD best practices, and drive adoption of new tooling across the org
• Join the on-call rotation to support systems and services during production incidents; contribute to root cause analyses and postmortems
• Participate in code reviews and author technical proposals that raise the engineering bar for the Builder Tools team

Benefits

  401k
• Flexible vacation policy

• Bachelor’s degree in Computer Science or related field, or equivalent experience
• Experience with Docker and container orchestration (Kubernetes or similar)
• Solid understanding of source control concepts and practical Git experience
• A developer empathy mindset: you build tools that are easy to adopt, well-documented, and reduce toil rather than create it
• Proven ability to troubleshoot complex systems and resolve issues efficiently
• 5–8 years of software engineering experience, with at least 2–3 years focused on CI/CD, developer tooling, or build infrastructure
• Hands-on experience building and maintaining complex CI/CD pipelines and build infrastructure — pipeline-as-code, artifact management, multi-environment deployments
• Strong programming fundamentals in Go, Python, TypeScript, or similar; track record of writing clean, maintainable, well-tested code
• Genuine curiosity and hands-on experience with AI coding tools and agents — Copilot, Cursor, Claude Code, or similar — and opinions about what makes them work well in a real codebase
• Experience building API-ready interfaces or harness tooling for AI coding agents
• Prior work on developer experience or engineering productivity programs
• Familiarity with GitOps principles and workflows
• Experience with static analysis, automated PR pipelines, or code review tooling
• Background in fast-paced or scaling startup environments
