Machining Enginer

Mach Industries • Huntington Beach, CA

95d

About The Position

Mach Industries is seeking a Machining Engineer to own the industrialization, optimization, and scaling of precision machining processes. You will collaborate closely with design engineering, prototype build teams, machinists, and quality to ensure that our parts are manufacturable, cost-effective, and robust under high volumes. You’re as comfortable in the CAM software as you are on the shop floor. At Mach Industries, we are building decentralized, autonomous systems to maintain an allied American edge in modern warfare. As a Machining Engineer, you will play a pivotal role in turning design concepts into hardware at scale. Working with a world-class engineering team, you will bridge the gap between design and manufacturing, delivering solutions that ensure manufacturability, cost-efficiency, and mission-critical reliability.

Requirements

• Bachelor’s degree in mechanical, aerospace, manufacturing engineering, or equivalent experience.
• 3+ years of hands-on machining / process engineering experience in a high-precision environment (internship and school projects experience qualifies).
• Deep understanding of machining fundamentals: cutting mechanics, tool life, feeds & speeds, material removal, thermal effects.
• Proficiency with CAM tools (e.g. Mastercam, Fusion360, etc.).
• Experience interpreting and applying GD&T, tolerancing, dimensional control, and inspection methods.
• Track record of process qualification, process control, and root-cause problem-solving.
• Strong communication skills; able to work cross-functionally across design, quality, and manufacturing teams.
• Ability to work on the shop floor, lead troubleshooting in real time, and engage with machinist feedback.

Nice To Haves

• Experience in aerospace, defense, automotive, or other high-rate production environments.
• Exposure to exotic materials (Inconel, titanium, high-strength alloys, stainless steels).
• Experience ramping prototypes into production, handing off processes to scalable manufacturing teams.
• Ability to write automation scripts or tool path optimization routines.

Responsibilities

• Develop, qualify, and optimize machining processes (turning, milling, multi-axis, etc.) for critical components.
• Translate design geometry and tolerances into robust, repeatable manufacturing methods.
• Work with design engineers early to influence design for manufacturability (DFM) tradeoffs and avoid costly designs.
• Design, validate, and improve CNC program files, fixturing, tool selection, setups, and process flows.
• Generate and maintain process documentation: operation plans, work instructions, inspection checklists, CNC program files.
• Implement process control strategies (SPC, capability studies, control charts) to monitor stability.
• Troubleshoot process issues: dimensional drift, tool wear, chatter, thermal effects, fixture instability, etc.
• Partner with prototype/build teams to transition successful processes into production.
• Drive continuous improvement: cycle time reduction, yield increase, cost-down initiatives.
• Partner with machinists and operators to ensure compliance, quality, and standard work execution.
• Support change control and process change implementation as part geometries or design evolve.

Benefits

• Health insurance
• Retirement plans
• Opportunities for professional development
