The role
You will perform mechanical integration of robots onto heavy mobile base platforms. You will design heavy-duty mechanical systems and architect reconfigurable platforms for construction environments.
What you will do
- Execute mechanical integration programs mating robotic arms and payloads to 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, gasketing, and thermal management.
- 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
- 3+ years of hands-on mechanical engineering experience with a focus on robotics, autonomous systems, or heavy equipment.
- Demonstrated initiative, creative problem-solving skills, and a self-starter mindset.
- Direct experience integrating robotic arms, actuators, or heavy payloads onto mobile platforms.
- Experience designing to IP67 or stricter and familiarity with shipping systems that survived real 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%) including active construction environments.
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.
