CNC Machinist III

Karman Space & Defense is a leader in the rapid design, development, and production of critical, next-generation system solutions that align with the U.S. Department of War and its allies’ core mission priorities and meet the accelerating demand for access to space. Building on nearly 50 years of success, we deliver Payload & Protection Systems, Aero/Hydrodynamic Interstage Systems, and Propulsion & Launch Systems to more than 80 prime contractors supporting over 130 space and defense programs. This role is part of our Space and Launch business, which has contributed to the nation’s space programs for decades by delivering complete solutions from concept to flight. We enable successful space operations with mission-critical technology supporting every step from first launch to final landing, including launch vehicle subsystems, propulsion systems, aerodynamic and interstage systems, and payload protection and deployment. Our high-performance solutions are engineered to operate in the most extreme environments and meet precise mission requirements. As a Machinist III, you will independently set up and operate advanced 3-, 4-, and 5-axis CNC machining centers to manufacture complex, mission-critical aerospace hardware. You will own machining execution from setup through dimensional verification, frequently working on one-of-one and low-volume components manufactured from difficult and high-value materials. This position requires advanced machining judgment, strong troubleshooting capabilities, and the ability to work collaboratively with Programming, Engineering, and Quality. The Machinist III reports to the Machine Shop Foreman and provides technical guidance to less-experienced machinists. Responsibilities Independently set up and operate complex 3-, 4-, and 5-axis CNC machining centers. Prove out setups for new or unproven components in collaboration with Programming and Engineering. Machine one-of-one, prototype, and low-volume flight hardware using Inconel, titanium, stainless steel, copper, and other exotic alloys. Perform conversational programming and controller-level G-code and M-code edits using Fanuc and/or Siemens controls. Install and qualify fixtures, workholding, cutting tools, probes, machine datums, and related setup components. Interpret engineering drawings, models, setup documentation, and Geometric Dimensioning and Tolerancing (GD&T) requirements. Perform first-piece and in-process dimensional verification while monitoring tool wear, machining conditions, and process stability. Independently troubleshoot machining, tooling, setup, and dimensional issues in partnership with Programming, Engineering, and Quality. Exercise stop-work authority when conditions may place personnel, equipment, or hardware at risk. Provide technical guidance and mentorship to less-experienced machinists. Required Qualifications High school diploma or equivalent. 5+ years of CNC machining experience in a precision manufacturing environment. Demonstrated ability to independently set up and operate complex 3-, 4-, and 5-axis CNC machining centers with minimal supervision. Experience machining one-of-one, prototype, or low-volume, high-value components. Experience machining Inconel, titanium, stainless steel, copper, and/or other exotic alloys. Conversational programming experience using Fanuc and/or Siemens controls. Basic CAM experience using Mastercam, ESPRIT, CATIA, or comparable software. Experience working within an AS9100 or equivalent quality management system. Strong blueprint-reading skills and practical knowledge of GD&T. Strong knowledge of cutting tools, workholding, fixturing, probing, feeds, and speeds. Proficiency using precision measuring and inspection equipment. Ability to exercise sound judgment and maintain composure while machining one-of-one and high-value aerospace hardware. Strong verbal and written communication skills. Preferred Qualifications Experience with large-format 5-axis machining. Experience machining additively manufactured components. Previous experience mentoring or providing technical guidance to less-experienced machinists. Advanced experience troubleshooting complex machining, tooling, dimensional, and process-related issues. Export Control Requirements This position requires access to information and/or hardware subject to U.S. export-control regulations, including the International Traffic in Arms Regulations (ITAR) and/or Export Administration Regulations (EAR). Candidates must qualify as a U.S. person as defined by applicable U.S. export-control regulations. First shift, Monday through Friday. Arlington, Washington #J-18808-Ljbffr
