Hardware Engineer

About Crewline

Crewline is building autonomous construction vehicles to transform how the world builds. Our mission is to tackle the inefficiencies in construction by deploying real robotics systems into real job sites. We are a team of builders who thrive in fast-paced, hands‑on environments and believe deeply in shipping hardware that directly impacts the physical world.

We are looking for a Hardware Engineer with 2–10 years of experience to help design and deploy the core hardware systems that power Crewline’s autonomous construction vehicles. This role is ideal for someone who is deeply passionate about robotics, excited to build from the ground up, and driven by seeing their work operate on heavy machinery in the field.

You will work across power, compute, sensing, control, and communication systems, supporting everything from early prototyping to full vehicle integration and deployment. This is a highly hands‑on role with direct ownership of real‑world systems.

• Design and develop teleoperation hardware systems, including power, compute, and control modules for heavy machinery retrofits
• Integrate and calibrate sensors including cameras, LiDAR, radar, GNSS, and IMUs
• Create wiring harnesses and mounting systems for sensors, actuators, and control electronics
• Implement and validate communication protocols including CAN, LIN, J1939, Ethernet, and Serial
• Support system bring‑up and hardware‑in‑the-loop (HIL) testing alongside software engineers

• 2–10 years of experience in hardware engineering
• Background in robotics, autonomous vehicles, heavy machinery, industrial automation, or other high‑reliability electromechanical systems
• Experience building from 0 to 1 in a startup, side project, or similar environment
• BS/MS/PhD in Electrical Engineering, Mechanical Engineering, Mechatronics, Robotics, or a related field
• Strong experience with electrical and mechanical integration, including wiring harnesses, power systems, sensor and actuator mounting, DFM, prototyping, and reliability testing
• Experience integrating sensors such as LiDAR, radar, GNSS/RTK, IMU, and stereo/mono cameras
• Familiarity with interfaces such as GMSL, Ethernet, CAN, LIN, J1939, and Serial
• Strong sense of ownership, grit, and a willingness to do what it takes to get systems working in the field

• Willingness to travel up to 50% of the time to active construction sites
• Ability to work on-site in San Francisco, CA
