About The Position

Hadrian is building autonomous factories to manufacture aerospace and defense components up to 10x faster and 2x cheaper, by integrating advanced software, robotics, and full-stack manufacturing. They are expanding with a new 290,000-square-foot facility in Mesa, Arizona, creating 350 new jobs, and are also launching Hadrian Maritime and a Factory-as-a-Service model. The company is backed by investors like T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, aiming to reindustrialize American manufacturing. The Builder Tools team is crucial for engineering speed and quality, owning the foundational tools, pipelines, and workflows. As a Software Engineer on this team, you will develop and maintain CI/CD infrastructure, internal tooling, and AI-assisted development workflows for all Hadrian engineers, focusing on making them faster. This includes managing shared pipeline libraries, streamlining the SDLC, enabling AI coding agents with internal systems, and automating repetitive tasks. This role is high-leverage, with improvements directly impacting the company's operational speed.

Requirements

• 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
• 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

Nice To Haves

• 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

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

Benefits

• Medical, dental, vision, and life insurance plans for employees
• 401k
• Relocation support may be provided for certain situations, based on business need.
• Flexible vacation policy
