Job summary

Blue Origin LLC is seeking a hands‑on CNC Machinist & Programmer to support emergent fabrication for Lunar Operations. You will review models, develop machining strategies, create CAM programs, and run 3‑axis/5‑axis mills and turning centers to produce flight‑relevant hardware.

The role requires 5+ years in CNC machining and programming, reading engineering drawings with GD&T, and strong problem‑solving skills for a fast‑paced development environment. Location: Space Coast, FL.

Qualifications

• High school diploma or GED plus relevant technical training, or equivalent hands‑on experience.
• 5+ years of combined CNC machining and programming experience producing tight‑tolerance hardware.
• Ability to read and interpret engineering drawings and GD&T per ASME Y14.5 at a working level.
• Experience holding tolerances to ±0.001 in or tighter where required, and selecting appropriate inspection methods to verify conformance.
• Proficiency with shop math and basic computer skills.

Responsibilities

• Program, set up, and operate 3-axis and 5-axis CNC mills and CNC lathes and turning centers to produce precision parts that meet engineering requirements.
• Create and prove‑out Siemens NX CAM programs, including tool selection, workholding approach, and cutting parameters, targeting HAAS equipment when applicable.
• Perform complete job execution from planning through inspection, including setups, setup sheets and tool lists, safe prove‑out, offsets and comp adjustments, and documentation for repeatability.
• Execute first‑article and development builds, optimizing feeds, speeds, toolpaths, workholding, and sequencing to improve cycle time, surface finish, and dimensional capability.
• Machine and finish components in materials like aluminum, stainless steels, Inconel, and Monel using disciplined tool‑life and heat management.
• Perform in‑process and final inspection using precision measurement tools like micrometers, calipers, height gages, indicators, and bore gages.
• Record inspection results clearly and support CMM and Metrology as required.
• Troubleshoot machining and process issues like chatter, tool wear and breakage, workholding distortion, dimensional drift, and surface damage, then implement corrective actions.
• Maintain a safe, organized shop environment and follow safety and quality procedures to protect flight and mission‑critical hardware.
• Support manual machining and benchwork like drill and tap, ream, deburr, blend, and fit up when CNC is not the best solution.
• Collaborate with Engineering, Quality, and Operations to clarify requirements, resolve discrepancies, and provide practical feedback on machinability and inspection approach while maintaining schedule.
