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 - 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 GROWTH & TRAJECTORY The Builder Tools team is being built from the ground up, and this is one of the foundational IC roles on it. As the team grows and the function matures, there are opportunities to specialize in AI-assisted developer workflows, CI/CD platform ownership, or SDK/API development — and to grow into a senior IC or tech lead role as the org scales. Compensation For this role, the target salary range is $173,000 - $321,000 (actual range may vary based on experience). This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs. BENEFITS FOR FULL-TIME EMPLOYEES - 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 - Equity   ITAR REQUIREMENTS To conform to U.S. Government export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen or national, lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

This may include tools that help organize and analyze recruiting data, as well as an AI-powered notetaker that can record and transcribe interviews and help coordinate feedback. These tools support our team and are not used to make hiring decisions. All candidate evaluations and hiring decisions are performed by humans. If an interview will be recorded, you will be notified in advance and may opt out at any time with no impact on your candidacy. Candidate data processed through these tools is subject to the same protections described in our Privacy Policy https://www.hadrian.co/privacy-policy.   CONSIDERATION OF CRIMINAL HISTORY Hadrian will consider for employment qualified applicants with criminal histories in a manner consistent with the requirements of all applicable laws. We do not ask about criminal history on our application, and we do not consider criminal history before making a conditional offer of employment.   HADRIAN IS AN EQUAL OPPORTUNITY EMPLOYER Hadrian does not unlawfully discriminate on the basis of race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, marital status, mental status, physical disability or any other legally protected status.
