Job description

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

Maintenance Specialists are Hadrian's rapid deployment force for installs, commissioning, and uptime across machines, robots, and site infrastructure across our factories. The Maintenance Specialist takes full ownership of all maintenance activities within a specific section of our state-of-the-art factory. You'll be integral to maintaining equipment efficiency and ensuring seamless production continuity. The role spans full-stack facilities systems -- electrical distribution, compressed air, vacuum, process cooling, HVAC, general utilities, and more -- demanding both broad technical range and thoughtful judgment.

What You’ll Do

• Perform timely and effective maintenance on CNC machinery, welding equipment, industrial manufacturing equipment, and robotic systems according to manufacturer guidelines, swiftly returning equipment to full operational status.
• Liaise directly with manufacturers or external vendors to resolve issues rapidly and efficiently.
• Diagnose and conduct root cause analysis for equipment breakdowns, distinguishing between mechanical, software, or other issues, and developing solutions to proactively mitigate future risks.
• Troubleshoot and repair control & electrical system failures involving PLCs, HMIs, servomotors, servo amplifiers, input/output, and field sensors.
• Troubleshoot and repair various machine tool hydraulic and pneumatic systems, including actuators, valves, pumps, and filters.
• Troubleshoot and repair automated tool mechanical systems such as ballscrews, linear rails, guideways, gearboxes, and 3-phase motors.
• Prioritize and manage maintenance tickets proactively to minimize equipment downtime.
• Drive forklifts, scissor lifts, and operate gantry crane as needed to perform repairs.
• Perform and maintain records of repairs and preventative maintenance on assets.

What We’re Looking For

• Experience performing mechanical and electrical maintenance on CNC machines, robotics, and welding equipment.
• Ability to learn quickly, leveraging self-discovery and external training resources as needed.
• Strong technical understanding of mechanical, electrical, and hydraulic systems within advanced manufacturing contexts.
• Clear communicator who can coordinate vendors and collaborate with engineers, operations; able to work off-shift or on-call during critical installs.

What Will Set You Apart

• Demonstrated experience installing and commissioning CNC machines, industrial robots, and associated automation in a live production environment.
• Broad facilities skill set across electrical (high- and low-voltage), mechanical, pneumatic, hydraulic, and HVAC systems; able to read schematics.
• Hands-on troubleshooting of drives, servos, PLC-adjacent I/O, sensors, VFDs, coolant and chip systems.
• Maintenance system literacy for work orders, parts, and preventive plans; disciplined documentation habits.
• Experience installing, aligning, and commissioning automated production cells in a production/R&D environment.

Compensation

For this role, the target salary range is $26-40/HR (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
