Senior 5-Axis CNC Programmer

Senior 5-Axis CNC Programmer to join thei Manufacturing Team. In this role, you will be machining complex, flight-critical components with extreme precision—contributing directly to spacecraft that will leave Earth and return with life-changing materials manufactured in microgravity.

This is a hands‑on, high‑impact role in a non‑production, prototype‑driven environment where you will work with cutting‑edge equipment, collaborate directly with engineers, and operate with full ownership of your machining processes. Youll be surrounded by industry veterans in a culture that values humility, speed, and craftsmanship.

Work Environment

• Autonomy and ownership. Responsible for print‑to‑part. Independent projects.
• One‑off prototyping work. You rarely work on the same part twice.
• New 5‑axis CNC machines. Premium tooling.
• Generous tooling and inspection budget. No need for personal tools.
• Single shift. No one else touches your machine.
• Clear aerospace environment. Pristine floors.
• Onsite in El Segundo, CA.
• 40-45 hours per week (over‑time available with approvals).
• Flexible hours and generous benefits.

• Machine complex aerospace components on 5‑axis mills (Haas UMC
  1000 etc.) to tolerances of ±0.0005 in.
• Execute the full print‑to‑part workflow with full autonomy, including CAM programming, custom fixturing, setup, machine operation, and inspection.
• Machine exotic materials such as PEEK, Inconel, stainless steel, and carbon composite materials.
• Design and execute custom fixturing and work‑holding solutions for prototype parts.

• Program CAM toolpaths using software such as Mastercam, HSMworks.
• Incorporate probing strategies and macros to reduce setup time and increase accuracy.
• Continuously refine feeds, speeds, and tooling strategies to minimize cycle times while maintaining aerospace‑grade quality.

• Take end‑to‑end ownership of machining processes, including raw material selection, programming, setup, machining, inspection, and documentation.
• Collaborate with engineering teams to provide Design for Manufacturability (DFM) feedback.
• Develop and standardize best practices to improve shop efficiency and knowledge sharing.

• 5+ years of experience programming and operating 5‑axis vertical machining centers (e.g., Haas UMC‑1000/750, DMG MORI DMU, or similar) producing tight‑tolerance aerospace or flight‑critical components.
• Proficiency in Mastercam for 3+2 and full simultaneous 5‑axis toolpaths, including simulation and verification.
• Deep understanding of G‑code/M‑code and advanced CNC program editing.
• Experience machining exotic materials and applying GD&T principles.
• Hands‑on experience with precision inspection tools.
• U.S. citizenship or lawful permanent residency (ITAR compliance).

• 10+ years of CNC machining experience, primarily in 5‑axis milling environments.
• 5+ years of Mastercam experience, including post customization and optimization.
• Skilled in custom work holding and fixture design, including modular dovetail, vacuum, and Lang‑style clamping systems for small‑lot prototype work.
• Demonstrated mentorship or leadership within a high‑precision machining environment.
• Familiarity with CNC lathes, mill‑turn, or live‑tooling equipment — nice to have but not required.
