Manufacturing Engineer, CNC

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.

We're hiring a Manufacturing Engineer with deep CNC machining expertise to join our team at the FX facility in Torrance, CA. You'll join a group of roughly twenty engineers and SMEs specialized across manufacturing capabilities — sheet metal, tube & pipe, and more — and bring dedicated machining depth at a moment when it matters most: our machining capacity and process maturity are directly on the critical path for one of Hadrian's highest-priority programs. This is a process development and qualification role, not a machine operation role. You'll define machining processes from CAM strategy through first-part-off and drive them to capable, repeatable production — turning tough titanium and Inconel parts into documented, validated processes. You'll be the machining voice in capital equipment decisions, supporting SMEs through capex selection, and you'll partner with the factory development team as new capability is installed, commissioned, and brought online. It's a role for an engineer who combines hands-on machining judgment with data-driven rigor (DOE, SPC, capability studies) and wants their fingerprints on both the parts and the machines we buy — all in a fast-moving, high-mix, low-volume environment.   What You’ll Do Lead CNC machining process development and research end to end — machining strategy, CAM/toolpath direction, cutting parameters, workholding and fixturing, and in-process probing — for complex, tight-tolerance aerospace and defense parts in a high-mix, low-volume environment (5-axis strongly preferred; mill-turn a plus), with a focus on steel, titanium and Inconel. Qualify processes to capable, repeatable production: first-article builds, process capability studies (Cp/Cpk), SPC, and DOE-driven parameter optimization. Serve as the CNC subject-matter expert supporting the capital equipment (capex) selection process — defining requirements and runoff criteria, evaluating machine tools, vendor assessment and capability studies, and factory acceptance testing (FAT). Support the factory development team as new machining capability comes online — providing machining expertise through equipment installation, commissioning, and machine bring-up from first-part-off to fully ramped and stabilized production. Provide Design for Machinability (DFM) feedback and tolerance definition to design and engineering teams, and drive cycle-time and cost-down improvements against aggressive program milestones.

4+ years of manufacturing engineering experience in CNC machining processes in aerospace & defense, precision manufacturing, medical device, or consumer electronics environments (a BS in Mechanical/Manufacturing Engineering is great; equivalent hands-on experience is just as valued). Deep multi-axis expertise: 3–5-axis simultaneous milling
