Senior Mechanical Engineer

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.

JOB SUMMARY:

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.

SKILLS AND REQUIREMENTS:

Proven ability to independently own and deliver mechanical subsystems or features

Strong experience with DFMA, manufacturing processes, and production support

Proficiency in mechanical analysis methods, including FEA and analytical calculations

Hands-on experience with prototyping, verification, and validation testing

Solid understanding of materials selection, GD&T, and tolerance stack-up analysis

Experience integrating mechanical designs with electronics, software, and motion systems

Familiarity with tooling, fixtures, automation, or test equipment design is a plus

Knowledge of regulatory, safety, and compliance considerations

Strong communication skills and ability to collaborate across disciplines

Demonstrated ability to mentor junior engineers and contribute to team technical standards

EDUCATION and/or EXPERIENCE

Bachelor’s degree in Mechanical Engineering

5+ years of experience in a related mechanical engineering role

PHYSICAL REQUIREMENTS
