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.
Hadrian is looking for a Maintenance Engineer to build and scale the systems that drive machine reliability, uptime, and maintenance execution across our factories. This role is closest to a manufacturing engineer focused on maintenance, and will own the content, scheduling, and process behind preventative, reactive, and predictive maintenance.
This person will be responsible for developing and optimizing our maintenance execution process and strategy, with direct impact on machine uptime, repair costs, and the processes executed by dozens of operators. They will work closely with Factory Technicians and Leads, Supply Chain, Maintenance Specialists and Technicians, Production Scheduling, and Factory Development.
This is a high-ownership role for someone excited to build a process from the ground up using modern tools and systems. The right candidate will help lay the foundation for how Hadrian manages preventative and predictive maintenance, and can influence procurement, CMMS development, and future machine selection as the company scales.
What You’ll Do
Maintenance Strategy & Asset Reliability
• Develop, implement, and continuously improve preventive maintenance (PM) programs for CNC machines, robotics, and automated systems
• Implement predictive maintenance (PdM) strategies using condition monitoring and equipment data
• Analyze equipment performance and trends to improve uptime, reduce failures, and extend asset life
• Lead root cause analysis (RCA) and implement corrective actions to prevent recurring issues
• Maintain accurate records of machine configurations, upgrades, and maintenance history
• Define and track key maintenance KPIs (uptime, MTBF, MTTR, PM compliance)
Systems, Data & Process Optimization
• Manage and optimize CMMS, including work order workflows, scheduling, and data integrity
• Develop dashboards and reporting to monitor maintenance performance and drive decision-making
• Standardize maintenance procedures, checklists, and documentation
• Identify and implement continuous improvement initiatives to reduce downtime and maintenance costs
Technician Support & Cross-Functional Collaboration
• Provide technical guidance and troubleshooting support to maintenance technicians
• Partner with production, engineering, and quality teams to improve machine reliability and performance
• Support new equipment installation, commissioning, and integration into maintenance programs
• Coordinate with OEMs and vendors for repairs, upgrades, and technical support
Safety & Compliance
• Ensure all maintenance activities follow safety standards and procedures (e.g., lockout/tagout)
• Promote a strong safety culture and ensure compliance with regulatory and internal requirements
What We’re Looking For
• Bachelor’s degree in Mechanical, Electrical, or related engineering field, or equivalent experience
• 3–7+ years of experience in CNC, manufacturing, or automation maintenance/reliability
• Strong understanding of CNC machines, PLCs, and industrial systems
• Experience with CMMS and maintenance planning tools
• Strong analytical, problem-solving, and organizational skills
• Ability to manage multiple priorities in a fast-paced environment
• Strong written and verbal communication skills
What Will Set You Apart
• Experience with predictive maintenance tools (vibration analysis, thermography, IoT monitoring)
• Knowledge of Lean Manufacturing or Six Sigma principles
• Familiarity with CNC/automation platforms (e.g., FANUC, Siemens, Haas)
• Experience supporting high-mix or high-end manufacturing
