Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond. We operate at the cutting edge of embodied AI, applying our expertise across the full robotics stack to solve some of society's most important problems.

You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better. JOB SUMMARY As a Senior Wire Harness Engineer, you are a core technical contributor responsible for the "nervous system" of our humanoid platform. You will design, route, and validate the complex wire harnesses that enable Apollo to move, sense, and think.

This role requires a strong blend of electrical system knowledge and mechanical integration. You will execute critical power and data distribution designs, ensuring our interconnect systems are robust, manufacturable, and optimized for high reliability in a dynamic electromechanical machine.

RESPONSIBILITIES

or KEY ACCOUNTABILITIEs Harness Design & Routing: Design, route, and document complex wire harness assemblies, developing detailed 2D/3D drawings, schematics, and full Bills of Materials (BoMs) using enterprise E-CAD software. Dynamic Joint Routing: Apply best practices for routing cables across high-DOF (Degree of Freedom) joints. Select wire types, jackets, and shielding materials that survive extreme dynamic environments and high-cycle fatigue.

Cross-Functional Collaboration: Act as a key technical bridge between Electrical Engineering, Mechanical Engineering, and Manufacturing. Optimize harness placement within tight spaces while balancing connector density, serviceability, and thermal constraints. Design for Excellence (DfX): Drive Design for Manufacturability (DfM) and Assembly (DfA) initiatives to reduce harness complexity, part count, and assembly time.

Support the integration of advanced techniques like overmolding and custom backshells. Testing & Failure Analysis: Conduct root cause analysis on harness and interconnect failures. , continuity, Hi-Pot, and pull-force tests) to identify and mitigate hidden failure modes.
