Senior Manufacturing Engineer, Turbomachinery Balancing

Huntington Beach, California, United States

Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.

Our vision is to redefine the future of warfare through cutting‑edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.

Mach Industries is seeking a Senior Manufacturing Engineer, Turbo machinery Balancing to establish, qualify, and scale balancing processes for our turbo machinery hardware. This role will support turbine wheels, compressor impellers and blisks, shafts, and complete rotating assemblies, taking balancing operations from development builds through repeatable production.

You will own the balancing process, including equipment selection and commissioning, tooling development, measurement validation, balance correction, and production implementation. We are looking for someone who has personally set up balancing stations, worked directly with rotating hardware, and demonstrated that the equipment, tooling, and process can consistently meet engineering requirements.

Working closely with Design Engineering, CNC Manufacturing, Quality, Test, and Automation, you will build a reliable internal balancing capability and translate specialized technical knowledge into robust processes that technicians can execute at production rate.

• Lead the specification, selection, installation, and qualification of balancing stations and associated equipment, including supplier coordination, factory acceptance testing, and site commissioning.
• Develop and validate component‑level and assembly‑level balancing processes for turbine wheels, compressor components, shafts, and complete rotating groups.
• Design, specify, and qualify balancing arbors, mandrels, collets, supports, and related fixtures, with emphasis on alignment, datum control, and repeatable part loading.
• Establish calibration, verification, and measurement‑system evaluation methods that demonstrate the capability of the complete balancing process, including the machine, tooling, hardware, and operator.
• Partner with CNC Manufacturing to develop controlled material‑removal correction processes that meet balance requirements while preserving dimensional conformity and component integrity.
• Work with Design Engineering and Test to translate product requirements into balancing specifications, approved correction features, inspection requirements, and acceptance criteria.
• Troubleshoot inconsistent balance results and identify root causes related to component variation, tooling, runout, assembly conditions, equipment setup, and measurement repeatability.
• Create controlled setup procedures, work instructions, troubleshooting guides, and safe operating practices; train technicians and provide hands‑on production support.
• Establish traceability for balance measurements, correction operations, tooling configurations, and final acceptance results in partnership with Quality and Manufacturing Systems.
• Improve cycle time, first‑pass yield, and process consistency while supporting automation and the transfer of validated balancing processes into production facilities.

• 5+ years of relevant experience in turbo machinery…
