Job description

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

Who We’re Looking For

We are seeking an experienced and hands‑on Lead Machinist to lead our Tulsa machine shop supporting the Ranger spacecraft program. In this role, you will oversee the manufacturing of tight-tolerance propulsion, structural, and tooling components for flight and test hardware. You will set up and operate multi‑axis CNC equipment, lead a team of machinists and quality inspectors, and take ownership of shop scheduling, quality, safety, and production performance.

You will play a critical role in establishing and scaling machining operations as Ranger transitions from development into production. Working closely with design and manufacturing engineers, you will support first‑article machining, develop repeatable manufacturing processes, and implement fixtures, tooling, and inspection methods that ensure consistent quality and production efficiency.

This position is ideal for a skilled machinist who leads by example, thrives in a hands‑on manufacturing environment, and enjoys mentoring others while producing precision components for mission‑critical spacecraft systems.

Where You’ll Make an Impact

• Lead a team of machinists and quality inspectors; set daily priorities, maintain the shop schedule, and act as point of contact when management is unavailable


• Set up, program, and operate multi‑axis CNC mills and lathes to produce propulsion, structural, and tooling components from aluminum, titanium, stainless, Inconel, and engineered plastics


• Hold tight tolerances and surface finishes on flight hardware, including sealing surfaces, fluid fittings, and precision bores


• Perform first‑article and in‑process inspection using CMM, optical comparators, and hand gauges; record results and drive corrective actions to improve part quality


• Review drawings, models, and GD&T with design and manufacturing engineers; give early, data‑backed feedback on manufacturability, tolerancing, and material selection


• Design and build fixtures, soft jaws, and work holding that make parts repeatable from the first article through rate production


• Write and maintain setup sheets, tool lists, and work instructions so any qualified machinist can run the job


• Cross‑train the team in CNC setup, inspection, and shop practices; coach junior machinists and raise the skill level of the shop


• Own tooling, cutter inventory, and preventive maintenance so machines stay up and output is predictable


• Enforce shop safety, FOD control, and material traceability for flight hardware


• Track throughput, scrap, and rework; communicate shop status, readiness, and risks to engineering and production leadership


• Work with the Hawthorne and Rockville teams to bring proven machining processes into Tulsa, and document parameters so they scale as the facility ramps to rate

What It Takes

• High school diploma or equivalency certificate


• 5+ years of experience with G-code, setup, operation, and/or programming of CNC mills and lathes


• 3+ years of experience machining to tolerances of ±0.0005\" or tighter and verifying them with precision inspection equipment


• Ability to read and interpret engineering drawings, models, and GD&T per ASME Y14.5

Nice-to-Have Experience

• 3+ years leading a team or shift in a machine shop environment


• 5+ years of 5-axis mill setup and programming experience


• Experience with multi‑axis lathes, live tooling, and horizontal and vertical mills


• CAM programming experience in Mastercam, Fusion 360, NX, or similar; CAD experience in NX, SolidWorks, or Creo


• Experience machining aerospace alloys, including titanium, Inconel, and 6061/7075 aluminum


• Experience with CMM programming and operation (Zeiss, Mitutoyo, Hexagon, or similar)


• Experience with propulsion or fluid‑system components: sealing surfaces, high‑pressure fittings, thin walls, and deep bores


• Experience designing and building fixtures and work holding for low‑volume, high‑mix production


• Familiarity with AS9100 quality systems, first‑article inspection per AS9102, and material traceability for flight hardware


• Experience standing up a new machine shop or production cell, including equipment selection, layout, and process transfer from a prototype shop


• Comfortable working directly with design engineers and pushing back on drawings with data


• Clear communicator who can keep a shop running without supervision and bring problems to leadership early

What You’ll Get

Ownership – Lead machining operations and precision component manufacturing for the Ranger spacecraft program, taking responsibility for shop performance, quality, and production readiness

Innovation – Develop and implement advanced CNC machining processes, tooling, fixtures, and manufacturing techniques supporting next‑generation spacecraft technologies

Impact – Play a direct role in producing high‑precision propulsion, structural, and flight hardware components that support critical national security, civil, and commercial space missions

Growth – Help establish and scale a new manufacturing facility while mentoring machinists, developing shop capabilities, and contributing to a collaborative, fast‑paced engineering and production environment

Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
