Fast deployment timeline

Job summary

Calder Search is seeking a Senior Mechanical Engineer to own a complete subsystem from concept through field deployment. You will lead CAD, analysis, prototyping, testing and production, ensuring seamless integration with other subsystems.

You’ll design for manufacturability, run FEA/CFD in-house, and drive fast but sound trade-offs to hit a functional 80% early. This on-site role targets rapid field deployment in the Los Angeles area.

Qualifications

• 5–7 years designing mechanical hardware from concept through production.
• Experience architecting and delivering a full subsystem, not contributing to one part of a larger program.
• Deep expertise in at least one area: exterior body design, structures, mechanisms, energy storage, or propulsion.
• Expert-level CAD (NX ideal; SolidWorks or CATIA considered) managing complex assemblies.
• Runs own analysis (FEA/CFD) rather than handing it to a dedicated analyst.
• Design for manufacturing experience working directly with machine shops and fabrication partners.
• Backgrounds in automotive or EV body design, aerospace fuselage/airframe, UAVs, robotics or marine systems.

Responsibilities

• Own a full mechanical subsystem from requirements and concept through CAD, analysis, prototyping, test and production.
• Coordinate integration so your subsystem works with the rest of the platform.
• Make fast, sound trade-offs to reach a working 80% solution while challenging requirements.
• Lead end-to-end development including validation, supplier interaction and field deployment.
