Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

The Role

Every engineer at Hadrian ships software. The speed and quality of that work depends directly on the tools, pipelines, and workflows underneath it. The Builder Tools team owns that foundation.

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.

This is a high-leverage role. The systems you build touch every engineer at Hadrian, and the improvements you ship show up immediately in how fast the company moves.

What You'll Do

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

What We're Looking For

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

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 rather than create it

Bachelor's degree in Computer Science or related field, or equivalent experience

What Will Set You Apart

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
