Real-Time Robotics Controls Engineer (Safety-Critical)

Lever, Inc.; Massachusetts; Hybrid; USD 150,000 - 300,000; Full time

Job summary

Tutor is seeking a controls engineer to own safety-critical control code for robotic arms deployed in customer facilities. You will implement the loop that converts motion commands to torque, set limits, manage stopping distances, and build hardware‑in‑the‑loop testing against real arms and safety hardware.

You will document decisions, monitor stopping times, and help grow a safety‑minded codebase written in C++ and Python on Linux.

Qualifications

• Real-time control on physical systems.
• Experience in mission-critical codebases with safety considerations.
• Comfort with physics: dynamics, inertia, stopping distances.
• Strong systems software skills: C++ and Python, Linux RT.
• Experience with hardware-in-the-loop testing.

Responsibilities

• Own the safety-critical control code for robot arms.
• Work on the control loop: timing, stability, failures.
• Organize code to be trusted: small, tested, reviewable.
• Build hardware-in-the-loop testing bench.
• Keep evidence current: stopping times and tests.
• Document the design and decisions.
