Senior Mechanical Engineer (Brooklyn)

Senior Mechanical Engineer – Humanoid Robotics

NYC/Brooklyn | $150K–$300K Base + Meaningful Equity | Early-Stage Start-Up

We’re working with an early-stage robotics company building highly capable humanoid robots designed to perform real-world physical work across manufacturing — including manipulation, assembly and other tasks traditionally performed by people.

You'll be joining a 5-person engineering team at the point where the product is moving from early prototypes into a much more sophisticated hardware platform. Following a significant funding round, they’re now scaling the core engineering team with 4–5+ hires across mechanical, electrical, controls and robotics.

As their Senior Mechanical Engineer, this is an opportunity to have real ownership of the physical architecture of the robot rather than owning one small part of an established product.

What you'll be doing

You’ll own the mechanical design of the robot, taking systems from concept through prototyping, testing and iteration.

• Designing mechanisms, joints, linkages and actuator systems
• Developing mechanical architectures for dynamic robotic systems
• CAD, prototyping and hands-on hardware testing
• Designing around motors, gearboxes, bearings and other electromechanical components
• Structural design, tolerancing, materials and mechanical analysis
• Designing for manufacturability, assembly and reliability
• Working closely with electrical, controls and robotics engineers
• Helping shape the mechanical architecture as the team scales

What they're looking for

• Mechanical Engineers with strong hands-on experience designing and building complex electromechanical systems.
• Experience with robotics, robotic arms, automation, actuators, mechanisms or other advanced hardware would be highly relevant.
• Strong CAD and mechanical design experience, with a track record of taking hardware from concept through prototyping and testing.
• You don't necessarily need previous humanoid robotics experience — they're interested in engineers who have worked on sophisticated moving hardware and enjoy solving difficult mechanical problems.

They’re looking to hire multiple engineers, with salaries ranging from $180,000–$300,000 base + meaningful equity .

If you've been waiting for the opportunity to join before the team and product are fully built, with a huge level of ownership over the mechanical design of the platform, this is exactly that.
