Los Angeles, CA, USA Posted on Mar 25, 2026 Apply now Hadrian - Manufacturing the Future

Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.

We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.

Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond

Join Us in Advancing Precision Machining

We are building advanced machining capabilities by integrating multi-axis CNC systems, large- format equipment, and precision tooling into a unified production environment. From raw stock processing through complex 5-axis machining and finishing, we treat machining as a tightly controlled system where kinematics, tool dynamics, and material behavior determine performance.

We are solving complex challenges in large-scale machining, multi-axis toolpaths, tight- tolerance work, and production scalability. This requires engineers with deep expertise in CNC systems, tooling, and process optimization.

This is a general opportunity to engage CNC engineers with specialized experience across key machining technologies.

Core Specialty Areas

Tooling & Workholding Systems: Tool presetting (standard, heat shrink, Regofix), tool life management, fixturing Cutting & Preprocessing: CNC bandsaw, waterjet cutting (including thick plate, large-format ~10ft x 20ft) Multi-Axis Machining: 5-axis machining (including U-axis configurations), complex toolpath strategies Large-Format Machining: Gantry mills (~8m class), horizontal boring mills (HBM), large envelope machining Turning & Mill-Turn Systems:Vertical turning lathes (VTL), mill-turn centers (long-bed, large diameter, multi-turret, B- axis) Precision & Non-Traditional Machining: Wire EDM, sinker EDM

What You’ll Do

Develop, program, and optimize CNC machining processes for precision, efficiency, and throughput Define tooling strategies, cutting parameters, and toolpaths for complex geometries and materials Partner with manufacturing and quality teams to ensure dimensional accuracy and process stability Lead root cause analysis for machining defects (chatter, tool wear, thermal distortion, tolerance drift) Create and maintain machining process documentation, setup instructions, and control plans

What We’re Looking For

Degree in Mechanical Engineering, Manufacturing Engineering, or equivalent hands-on machining experience Demonstrated expertise in CNC machining, multi-axis programming, or tooling systems Strong understanding of machining physics (cutting forces, tool wear, heat generation, vibration) Ability to interpret complex technical drawings and GD&T requirements Experience in production environments with tight tolerances and high precision requirements

What Will Set You Apart

Experience with large-format or heavy machining systems (gantry, HBM, large VTL) Deep expertise in 5-axis programming and advanced CAM strategies Familiarity with difficult-to-machine materials (e.g., titanium, Inconel, hardened steels) Experience in aerospace, defense, or other high-precision manufacturing environments
