Gritt
Senior Mechanical Engineer - Robotic Platforms
South San Francisco. Posted 6 months ago
The role
You will lead mechanical integration programs to mate robotic arms and payloads to heavy mobile base platforms. You will design heavy-duty mechanical systems and architect reconfigurable platforms for construction environments.
What you will do
- Lead mechanical integration programs for robotic arms and payloads on skid-steer and tracked vehicle platforms
- Design and specify heavy-duty mechanical systems like mounts, brackets, enclosures, actuators, and end-effectors
- Architect platforms for reconfigurability across construction tasks
- Own environmental strategy including IP67-rated enclosures, thermal management, and ingress protection
- Design, route, and validate wire harnesses and cable assemblies
- Integrate sensor and lighting packages
- Drive DFM, DFA, and DFS from the first CAD review
- Run structural analysis and own the validation plan for vibration, shock, thermal, ingress, and EMI
- Work with machine shops, sheet metal vendors, and harness houses
- Go to the field to diagnose failures and instrument systems
Required qualifications
- 7+ years of mechanical engineering experience
- Experience 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
- Proven track record designing to IP67 or stricter and shipping systems for outdoor deployments
- Strong hands-on cabling and harness design experience
- Expert CAD proficiency (OnShape/SolidWorks)
- Comfort with GD&T, tolerance stacks, and production-quality drawings
- Structural analysis chops on heavy systems
- Comfort moving fast in a scale-up
- Willingness to travel to field sites (~15–25%)
Nice to have
- Experience specifically with construction equipment, agricultural equipment, mining robotics, or defense ground vehicles
- Experience designing platforms intended to support multiple end-effectors, payloads, or task configurations
- Background integrating perception stacks
- Familiarity with hydraulics, pneumatics, or high-current DC power distribution on mobile platforms
- Experience owning supplier relationships for castings, weldments, or large machined parts
- Prior work on systems operating in desert Southwest or northern-climate conditions specifically
