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. Gritt systems are already building critical infrastructure in the harshest outdoor environments, starting with large-scale solar. The founding team https://www.gritt.ai/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. 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. Because our platform is general-purpose, you won’t be designing for one task forever. The same base robot needs to handle different end-effectors, payloads, and workflows as we expand across construction. Designing for that kind of reconfigurability - without giving up ruggedness - is a core part of the job. This is a hands-on senior role. You should be equally comfortable in CAD, on the shop floor with a torque wrench, and at a job site debugging a harness failure at 6 a.m.. What You’ll Do - Lead mechanical integration programs that mate robotic arms and payloads to skid-steer and tracked vehicle platforms - structural mounting, load paths, power/data routing, and service access. - Design and specify heavy-duty mechanical systems - mounts, brackets, enclosures, actuators, end-effectors - built to survive continuous outdoor duty cycles on active construction sites. - Architect platforms for reconfigurability so we can adapt across construction tasks (PV, rebar, block work, and future applications) without rebuilding from scratch each time. - 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. - Integrate sensor and lighting packages (cameras, LiDAR, IMUs, work lights, indicators) with attention to field-of-view, vibration isolation, cleanability, and serviceability. - Drive DFM, DFA, and DFS (design-for-service) from the first CAD review, not as an afterthought. - 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. - Work directly with machine shops, sheet metal vendors, and harness houses. Release drawings, manage ECOs, and hold vendors to spec. - Go to the field. Diagnose failures, instrument systems, and carry learnings back into the next revision. What We’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 h
