JOB SUMMARY

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 Applied 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.

We are seeking a Senior Mechanical Engineer to design and develop our Apollo humanoid robots across the full product lifecycle—from concept through production and sustaining.

In this role, you will apply strong engineering fundamentals and practical experience to solve well-defined and moderately ambiguous technical problems. You will collaborate closely with cross-functional partners in electrical, software, manufacturing, quality, and operations to deliver designs that meet performance, reliability, cost, safety, and manufacturability requirements.

Senior engineers are expected to own significant subsystems or features, execute with minimal supervision, and contribute meaningfully to technical discussions and design reviews. This role includes informal mentorship of junior engineers and participation in team technical standards, but does not require org-wide technical leadership.
