Manufacturing Engineer, Vehicle Assembly Huntington , California,

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 Manufacturing Engineers to develop and launch the Vehicle Assembly processes for our autonomous defense vehicles. You will own the processes, stations, and tooling for an assigned area of the assembly line. You'll take that area from late-stage prototype builds to full-rate production at Mach's Forge factories, with high first-pass yield at target cycle times.

You will own launch readiness for your area. Your stations, tooling, work instructions, parts, and equipment must be ready for each build. You'll work directly with Design Engineering, Supply Chain, Packaging Engineering, Material Flow, and Automation and Equipment Engineering to close gaps before they affect production. You'll also work closely with the Lead Manufacturing Engineer, Vehicle Assembly, and with Build Engineering, Manufacturing Operations, Quality, and Factory Design.

Launch Readiness for Your Area

• Own launch readiness for your assigned stations or line section, from late-stage prototype builds through full-rate production. Track open items against the launch schedule, and report status to the Lead Manufacturing Engineer.
• Work directly with partner teams to make sure your area is ready for each build:
• Design Engineering: resolve manufacturability issues and track engineering changes that affect your stations.
• Supply Chain: confirm part availability and supplier quality for your area.
• Packaging Engineering and Material Flow: confirm that containers, lineside part presentation, and part delivery are in place.
• Automation and Equipment Engineering: confirm that equipment and tooling for your area are built, installed, and accepted on schedule.
• Raise risks early and elevate them with a proposed solution. Put temporary workarounds in place when needed to protect the build.

Design for Assembly and Virtual Builds

• Review parts and assemblies for manufacturability (DFM/A), and recommend changes that reduce part count, simplify assembly, and prevent errors.
• Prepare and present your area's content in virtual builds, including assembly sequence, hand and tool clearance, tolerance concerns, and part presentation.

Process, Stations, and Equipment

• Develop the process for your area, including build sequence, station content, line balance, and cycle time.
• Estimate cycle times using predetermined motion time systems (e.g. MODAPTS).
• Design or specify fixtures, hand tools, lift assists, and fastening equipment. Define process requirements for the conveyance and automated cells in your area.
• Update station layouts with Factory Design, and set lineside part-presentation requirements with Packaging Engineering and Material Flow.
• Support equipment cost estimates and requests for quote (RFQs). Take part in vendor design reviews, factory acceptance testing (FAT), and site acceptance testing (SAT) for equipment in your area.

Builds, Ramp, and Production

• Support prototype builds and manufacturing trials, including prototype tooling, and apply lessons learned to the production process.
• Write and release work instructions and quality gates in the manufacturing execution system (MES), and help train technicians on new processes.
• Provide daily floor support during builds and ramp. Track first-pass yield, OEE, and cycle time for your area, and fix issues quickly.
• Use SPC, PFMEA, and structured problem-solving (8D, DMAIC, 5 Whys) to improve quality and throughput.

Additional Scope at the Senior Level

• Own launch readiness for a full line section or subassembly line, and give go/no-go input for each build.
• Lead DFM/A reviews and virtual builds for your section.
• Lead equipment projects for your section from requirements through SAT, working with Automation and…
