Lead Machinist

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.

Location: Tulsa, OK

Hourly Rate: $30-38 per hour

The salary range for this role is an estimate based on a wide range of compensation factors. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in the majority of full time offers; and are considered part of Quantum Space's total compensation package.
