Build Engineer

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 We are seeking a Manufacturing (Build) Engineer to support both early-stage and customer-driven builds. This role is responsible for translating design and customer requirements into executable factory processes through hands-on build execution and rapid iteration. You will lead the development of highly automated work cells to support new manufacturing capabilities and production facilities. In this position, you will serve as the operational connector across the Special Projects team, building end-to-end systems and processes that are scalable, robust, and aligned with Hadrian’s broader production objectives. What You’ll Do

• Lead the design and development of first-generation manufacturing systems and automation tools from concept through deployment.

• Collaborate with cross-functional teams, including design, production, supply chain, controls, software, and robotics, to implement strategic and process improvements.

• Communicate proactively with design engineering teams to provide early feedback on manufacturability and support iterative product development cycles.

• Apply DFM (Design for Manufacturability) principles at the product level to ensure ease of production, cost efficiency, and scalability.

• Own and drive upgrades and autonomous system developments that support high-reliability production and rapid iteration.

• Analyze and troubleshoot equipment to optimize uptime, output quality, and process efficiency.

• Identify, define, and deploy automation opportunities using internal capabilities or external partnerships, guided by rigorous ROI and technical evaluations.

What We’re Looking For

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Mechatronics, or a related field, or equivalent practical experience.

• 5+ years of experience in manufacturing environments, particularly in systems engineering or automation deployment roles.

• Proven ability to collaborate with design engineers on early-stage product development, including translating design intent into robust manufacturing solutions.

• Strong DFM expertise with a track record of influencing design decisions to enhance manufacturability, reduce costs, and accelerate time-to-market.

• Demonstrated ability to lead complex projects and drive cross-functional alignment in fast-paced, iterative settings.

• Strong quantitative and analytical skills for data-driven problem solving and process improvement.

• Excellent communication, documentation, and team-building skills, with a hands-on, solution-oriented mindset.

What Will Set You Apart

• Experience transitioning products from prototype to scalable volume manufacturing.

• Background in implementing automation and test systems into production workflows.

• Proficiency in data tools such as Excel and SQL for manufacturing analytics and process control.

• Experience managing or mentoring high-performing engineering teams with diverse technical backgrounds.

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
