Job summary

Hadrian is hiring a Software Engineer for the Builder Tools team to own CI/CD infrastructure, internal tooling, and AI-assisted development workflows used by all Hadrian engineers. You will create shared libraries, tooling, and automation to accelerate software delivery.

The role emphasizes building scalable CI/CD capabilities, API-ready components for AI agents, and a culture of high-quality, maintainable code.

Qualifications

• 5–8 years of software engineering experience, with 2–3 years focused on CI/CD or build infrastructure.
• Hands-on experience building and maintaining complex CI/CD pipelines and build infrastructure.
• Strong programming fundamentals in Go, Python, TypeScript, or similar; write clean, maintainable, well-tested code.
• Experience with Docker and container orchestration (Kubernetes or similar).
• Solid understanding of source control concepts and practical Git experience.
• Proven ability to troubleshoot complex systems and resolve issues efficiently.
• A developer empathy mindset: you build tools that are easy to adopt, well-documented, and reduce toil.

Responsibilities

• 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
