Freelance Hardware Integration Engineer Jobs (NOW HIRING)

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.

Apptronik is building Apollo, one of the world’s most advanced humanoid robots. As we scale from prototype to fleet deployment, we need a high-level technical leader to ensure our hardware remains resilient in the real world.

As a Staff Integration Engineer, you are the "Connective Tissue" of our engineering organization. You will lead a high-stakes, cross-disciplinary task force—spanning Mechanical (ME), Electrical (EE), and Wire Harness engineering—to diagnose systemic issues, drive rigorous Root Cause Analysis (RCA), and implement permanent corrective actions across our Apollo fleet.

• Cross-Disciplinary Leadership: Lead a dedicated team of ME, EE, and Harness engineers. You aren't just managing tasks; you are providing the technical vision to solve problems that sit at the intersection of these disciplines.
• Systemic Root Cause Analysis: Spearhead deep-dive investigations into fleet-wide failures. Whether it’s a signal integrity issue in a high-density harness or a thermal fatigue failure in a joint actuator, you drive the path to 'Why.'
• Corrective Action & Implementation: Own the lifecycle of hardware improvements. This includes drafting Engineering Change Orders (ECOs), validating fixes in the lab, pushing design to production, and overseeing the rollout of retrofits to the Apollo fleet.
• Fleet Telemetry & Diagnostics: Partner with software and data teams to utilize robot telemetry. You will define the monitors and error codes needed to catch integration 'drift' before it leads to downtime.
• Design Feedback Loop: Act as the primary bridge between Field Operations and R&D. You will translate field failures into actionable design requirements for the next generation of humanoid hardware.
• Reliability: Proactively initiate and lead improvement initiatives to enhance system reliability and increased uptime.

• Education: B.S. or M.S. in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field.
• Experience: 8+ years in hardware integration, systems engineering, or robotics. You have a proven track record of bringing order to chaos in complex electromechanical systems.
• The 'Generalist' Edge: You are an expert in one field but can speak the 'language' of all three (ME, EE, Harness).
• Problem Solving: Expert-level experience with RCA methodologies (Fishbone, 5 Whys, 8D, FMEA).
• Proven experience sustaining hardware products throughout their lifecycle, including failure analysis, board-level debugging, and collaboration with manufacturing and quality teams. Proven ability to identify recurring issues, drive root cause analysis, and implement design or process improvements to enhance system reliability and reduce field failures.

• Ability to perform physical tasks throughout the workday, including extended periods of sitting, and some standing, walking, bending, kneeling, climbing, and reaching.
• Ability to lift, carry, push, or pull up to 15 pounds as required.
• Ability to work in mechanical rooms, warehouses, offices, and other facility spaces.
• Vision and hearing sufficient to safely perform job duties and communicate effectively.
