Job summary

Blue Origin is seeking a highly skilled CNC Machinist to join the machining team for our advanced hardware program. You will set up, operate, and optimize 3- to 5-axis machining of high-precision components from nickel superalloys and stainless steels.

Responsibilities include interpreting drawings with GD&T per ASME Y14.5, selecting tooling, performing first-article runs, and supporting process qualification and continuous improvement in a fast-paced aerospace environment.

Qualifications

• High school diploma or GED required.
• 5+ years aerospace manufacturing experience.
• 2+ years with multi-axis lathes and 5-axis mills producing complex parts to tight tolerances.
• 2+ years machining hardened metals including nickel-based alloys, stainless steels, and high-temperature superalloys.
• Experience with CNC controls such as Mazak, Okuma, Fanuc, Heidenhain, Siemens, or equivalent platforms.
• Strong blueprint reading skills, including GD&T per ASME Y14.5; ability to interpret engineering models, drawings, specifications, written work instructions, and test procedures.
• CAM software experience, preferably Siemens NX.
• Proficiency with precision measurement instruments (micrometers, bore gauges, indicators, CMM, surface profilometers).
• Close attention to detail in a fast-paced, dynamic team environment with changing priorities.
• A continuous improvement mindset.
• Strong verbal and written communication skills and a customer-focused approach.
• Ability to work cooperatively with cross-functional teams across geographic distances.
• Strong organizational and analytical skills, with the ability to drive projects with minimal oversight.

Responsibilities

• Set up and operate multi-axis CNC milling machines (3-axis through 5-axis) to produce precision components per engineering drawings and process plans.
• Set up and operate CNC lathes and turning centers for precision shaft, housing, and case machining.
• Interpret engineering drawings with complex GD&T requirements and plan machining sequences to achieve specified tolerances.
• Provide machinability feedback directly to design engineering, advising on tolerancing, feature accessibility, fixturing constraints, and material selection to improve producibility before designs freeze.
• Evaluate and recommend CNC machines for the long-term production equipment plan, assessing machine tool capability, work envelope, accuracy, and throughput against program requirements.
• Perform first-article machining for new part numbers, optimizing feeds, speeds, tool paths, and fixturing for challenging materials and geometries.
• Perform in-process measurement using precision instruments (CMM, micrometers, bore gauges, surface profilometers) and make offset adjustments to maintain tolerance.
• Support post-processing of additively manufactured parts, including finish machining of AM components to final dimensions.
• Maintain tooling inventories, perform tool life management, and recommend tool selection for new applications.
• Document machining results, tool life data, and process parameters for production knowledge capture.
• Support process qualification and capability studies (Cp/Cpk) for critical dimensions.
• Maintain equipment through basic preventive maintenance and identify issues requiring maintenance support.
