JOB DESCRIPTION

At JPL, we ask the biggest questions and search the universe for answers. Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, cultivate innovation, build collaboration, and reward excellence!

This unique opportunity is part of the Manufacturing, Packaging, and Test Services Section, reporting directly to the Group Supervisor for Precision Machining & Fabrication Services. This section maintains the advanced technical facilities required to fabricate, assemble, and test electro-mechanical developmental and flight hardware for current and future missions.

We are seeking a Prototype Machinist—a technology-driven craftsperson who excels at turning one-of-a-kind engineering designs into space-qualified flight components. In this role within Precision Machining & Fabrication Services, you will produce highly complex prototype spacecraft hardware using advanced manufacturing methods.

Some Challenges You Will Solve:

• Program, set up, and operate a variety of 3 to 5 axis CNC machining centers (including Makino, Matsuura, Mitsui Seiki, DMG Mori, and Haas) within established process plans to manufacture complex, high-precision components from metallic and non-metallic materials.
• Manufacture high-precision parts to exceptionally tight tolerances.
• Collaborate with shop leads and Manufacturing Engineers to follow established process plans and meet approved machining estimates.
• Manage and run multiple machining resources simultaneously to support efficient shop operations.
• Perform routine equipment maintenance and scheduled Preventive Maintenance (PMs).
• Train and assist less experienced machinists, ensuring adherence to safe operating procedures on shop equipment.
• Contribute to shop productivity improvements by identifying opportunities to reduce cycle times and support efficient machining practices.

REQUIRED SKILLS

• A High School diploma with a minimum of 8 years of related experience; an Associate's degree with a minimum of 4 years of related experience; or a Bachelor's degree with a minimum of 1 year of related experience, plus completed technical training.
• Extensive hands‑on experience and programming proficiency in 3‑axis CNC milling, with working experience in 5‑axis machining and programming under established process plans.
• Proficiency in CAD/CAM programming tools—specifically Mastercam—with at least 2 to 3 years of programming experience.
• Strong ability to read and interpret complex blueprints and Geometric Dimensioning and Tolerancing (GD&T), with the capability to self‑inspect parts.
• An innovative mindset and the ability to apply complex machining techniques, working with limited day‑to‑day supervision to develop practical solutions to machining and fabrication challenges ordinarily encountered in the shop.
• A solid understanding of Electrostatic Discharge (ESD) protective protocols when handling sensitive flight electronic hardware undergoing modification.

DESIRED SKILLS

• 10+ years of prior aerospace or space industry programming and machining experience dealing with prototype and flight hardware.
• Experience with the programming, setup, and operation of CNC lathes (e.g., Okuma, Mori Seiki, and Monarch).
• Experience with the programming, setup, and operation of Electrical Discharge Machining (EDM).
• Solid background in conventional machining and precision toolroom operations.
• Experience assisting with shop coordination or informal leadership activities.
• Experience using Vericut software simulations for collision detection and verification.
• Effective written and verbal communication skills.
