Senior Manufacturing Engineer, Machining

Long Beach, LA

We are working with an exciting Deep Tech company that are developing advanced thermal-management systems built around high-speed, electrically driven turbo machinery.

The company is seeking a Lead Manufacturing Engineer to help establish and scale its internal CNC machining capability. You will support precision-machined rotor hardware, casings and structural components as they progress from initial prototypes into repeatable production.

This is a hands-on position combining CNC process development, design for manufacturability and machine-shop strategy within a fast-moving engineering environment.

• Develop and execute the strategy for an internal CNC machine shop.
• Establish machining processes, equipment standards, workforce requirements and production systems.
• Provide DFM feedback covering GD&T, datum structures, tolerances and overall machinability.
• Develop, troubleshoot and improve CNC programs, setups and processes for mills, lathes and multi-axis machines.
• Create manufacturing process plans, standard operating procedures and inspection plans.
• Design work holding and fixturing for complex, high-precision components.
• Investigate non-conforming hardware and lead root-cause and corrective-action activities.
• Support the selection, installation and qualification of machine tools, cutting tools and metrology equipment.
• Work closely with design, manufacturing and quality teams to move hardware from prototype into repeatable production.

• At least five years of experience in machining, manufacturing engineering or a closely related discipline.
• Experience developing CNC machining processes for complex, tight-tolerance components.
• Working knowledge of CNC milling, turning and multi-axis machining.
• Strong understanding of GD&T in accordance with ASME Y14.5.
• Experience with tolerance stack-up analysis and complex engineering drawings.
• Ability to work effectively with limited documentation in a prototype or fast-paced manufacturing environment.
• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering or equivalent practical experience.

• CAD/CAM proficiency using Siemens NX, Mastercam or a comparable platform.
• Experience designing machining fixtures and work holding.
• Knowledge of dimensional inspection and metrology methods.
• Experience manufacturing impellers, rotors, casings or other turbo machinery components.
• Experience with large vertical turning lathe operations.
• Background working with aerospace, rotating equipment, cryogenic or high-pressure hardware.
• Experience introducing lean manufacturing or continuous-improvement practices.
• Previous experience helping build or scale a machine shop within a startup or high-growth environment.
