About the role

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 tradeoffs on structure, mounting, sealing, thermal, and serviceability, and you'll make them fast.
Because our platform is general-purpose, you won't be designing for one task forever.

We encourage you to bring creative, high-impact design solutions to the team.
Design and specify heavy-duty mechanical systems - mounts, brackets, enclosures, actuators, end-effectors - built to survive continuous outdoor duty cycles on active construction sites.
Own the environmental strategy: IP67-rated enclosures, gasketing, connector selection, thermal management across roughly -20°F to 120°F+, and ingress protection against dust, mud, rain, and snow.
Design, route, and validate wire harnesses and cable assemblies - strain relief, chafe protection, connector selection, service loops, and harness documentation a contract manufacturer can actually build.
Drive DFM, DFA, and DFS (design-for-service) from the first CAD review, not as an afterthought.
own the validation plan - vibration, shock, thermal, ingress, EMI - and see it through test.
Work directly with machine shops, sheet metal vendors, and harness houses. Release drawings, manage ECOs, and hold vendors to spec.
Run structural analysis (hand calcs and FEA) on critical load-bearing components; own the validation plan - vibration, shock, thermal, ingress, EMI - and see it through test.
Gritt https://www.gritt.ai/ is an intelligent system that combines robotics and AI to build the infrastructure that pulls society forward.
Gritt deploys via simple attachments to common equipment found on construction sites and autonomously performs labor-intensive tasks, verification, and planning.

3+ years of hands-on mechanical engineering experience, with a focus on robotics, autonomous systems, or heavy equipment, and an eagerness to move quickly from prototype to deployment.
Experience designing to IP67 (or stricter) and familiarity with shipping systems that have survived real outdoor deployments across rain, snow, sub-zero cold, and high-heat/high-dust environments.
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.
Comfort moving fast in a scale-up: you've lived through the transition from one-off prototypes to low-volume production and know where the landmines are.
Experience specifically with construction equipment, agricultural equipment, mining robotics, or defense ground vehicles.
Familiarity with hydraulics, pneumatics, or high-current DC power distribution on mobile platforms.
Experience owning supplier relationships for castings, weldments, or large machined parts.

What We're Looking For
Designing for that kind of reconfigurability -without giving up ruggedness - is a core part of the job.
