Location: Long Beach, CA

You will own the mechanisms that customers touch every day. Hoods, liftgates, doors, fuel and charge port doors, running boards, tonneau systems and the exterior accessories that hang off them. This is a clean sheet program, not a carryover, which means you will define kinematics, effort targets and hardware architecture rather than inherit them. You will personally build and drive the CAD, run the studies that prove the motion works, and stay with the component through DV, PV and launch.

The team is small and flat, so the engineer who owns the design also owns the supplier, the build issues and the fix.

• Own exterior mechanism components end to end, from concept and packaging through design, validation and production launch.
• Design and release hinges, latches, strikers, check links, gas struts and spindle drives, actuators, cables and linkage systems, working to opening and closing effort targets, cycle life and load cases.
• Build and maintain your own CAD in 3DX and CATIA. Develop kinematic studies, motion envelopes, swing paths, tolerance stacks and clearance to surrounding structure, sheet metal and trim.
• Define and drive DFMEA, DVP&R, and test plans. Work with test and validation teams to close open items and document compliance evidence.
• Apply design for manufacturing across injection molded, sheet metal and stamped components, including draft, gate and parting line strategy, tooling feasibility, and forming and weld constraints.
• Source and manage suppliers through the full development cycle: technical reviews, design gates, tooling kickoff, PPAP support, and issue resolution on their side and ours.
• Support prototype and pilot builds hands on. Be at the vehicle, find the root cause, and drive the change through release.
• Coordinate with Studio, Body, Closures, Interiors, Electrical and Manufacturing to hold design intent while resolving competing requirements.
• Manage part release, change actions and BOM accuracy through the program’s PLM and change control process.

• Bachelor's degree in Mechanical Engineering or a related discipline.
• 5 or more years of automotive or comparable product development experience owning mechanical components through launch.
• Direct design and release experience on mechanisms, linkages, hinges, latches, struts or similar motion hardware.
• Demonstrated hands on CAD ownership. You built the geometry yourself and can walk through the decisions in it.
• Working knowledge of injection molding and sheet metal manufacturing processes and their design constraints.
• Experience with GD&T, tolerance stack analysis, DFMEA and DVP&R.
• Supplier facing experience through tooling, build and launch.
• Ability to work onsite in Long Beach.

• Experience on a clean sheet or startup vehicle program where the process was still being defined.
