## About the role

You’ll own the mechanical integration of our robots onto heavy mobile base platforms - skid-steers and tracked vehicles in the 10,000 lb class - and lead programs that take systems from prototype to repeatable field deployment across construction environments. Our arms are heavy, our payloads are heavier, and our operating conditions run from Arizona desert heat to sub-zero winter cold. You’ll make hard trade-offs on structure, mounting, sealing, thermal, and serviceability, and you’ll make them fast.

## What they're looking for

- 7+ years of mechanical engineering experience, with meaningful time at a robotics, autonomous systems, or heavy equipment company that scaled real hardware into the field
- Direct experience integrating robotic arms, actuators, or heavy payloads onto mobile platforms - skid-steers, tracked vehicles, AGVs, off-road equipment, or equivalent heavy machinery
- Proven track record designing to IP67 (or stricter) and shipping systems that have survived real outdoor deployments across rain, snow, sub-zero cold, and high-heat/high-dust environments
- Strong hands-on cabling and harness design experience - you’ve specified connectors, drawn harness diagrams, and debugged the problems that come back from the field
- Expert CAD proficiency (OnShape/SolidWorks) and comfort with GD&T, tolerance stacks, and production-quality drawings
- Structural analysis chops on heavy systems - you can size a weldment, pick a bearing, and know when to run FEA vs. when hand calcs are enough
