About Gritt

Gritt is an intelligent system that combines robotics and AI to build the infrastructure that pulls society forward. Doing real work on real jobsites, today. Backed by USV.

About the role

You will play a critical hands-on role in the mechanical integration of our robots onto heavy mobile base platforms - skid-steers and tracked vehicles in the 10,000 lb class - and design and support 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.

What they're looking for

  • 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
  • Demonstrated initiative, creative problem-solving skills, and a self-starter mindset in an environment with ambiguous technical problems
  • Direct experience integrating robotic arms, actuators, or heavy payloads onto mobile platforms - skid-steers, tracked vehicles, AGVs, off-road equipment, or equivalent heavy machinery
  • 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
  • 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
More about this role

Gritt 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. Gritt systems are already building critical infrastructure in the harshest outdoor environments, starting with large-scale solar. The founding team includes experts in robotics and AI from Carnegie Mellon, Stanford, and MIT. Gritt is backed by Obvious Ventures, Union Square Ventures, First Round Capital, Climactic, Congruent Ventures, and other leading firms.

You will play a critical hands-on role in the mechanical integration of our robots onto heavy mobile base platforms - skid-steers and tracked vehicles in the 10,000 lb class - and design and support 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 tradeoffs on structure, mounting, sealing, thermal, and serviceability, and you’ll make them fast.
