What are the responsibilities and job description for the founding mechanical engineer position at Stealth Robotics Startup?
About us
We’re building the next generation of human-machine connection: a humanoid robotics platform that isn’t We’re developing a lifelike robotic face - a platform for emotional expression and human-robot connection. Think of it as the “emotive layer” that lets humanoid robots feel more alive and relatable.
We’re looking for a founding mechanical engineer who can turn expressive motion into precise, manufacturable mechanisms. Someone who enjoys working close to hardware, iterating quickly, and helping shape both the product and the culture from the beginning.
- Design and prototype high-fidelity facial mechanisms - small-scale linkages, actuator systems, compliant structures - that can convey humanlike motion
- Build and test physical prototypes: from CAD and 3D prints to silicone assemblies and final test rigs
- Collaborate closely with the rest of the team to integrate sensors, drivers, and motion control into a unified system
- Own the mechanical stack: materials, tolerances, manufacturability, assembly, and test plans
- Support early manufacturing decisions - DFM/DFA, vendor coordination, and rapid iteration cycles
- Help establish engineering practices and documentation standards as we scale
- 5 years in mechanical design, robotics, mechatronics, or similar
- Strong CAD and prototyping skills
- Experience with fine-scale actuation, compliant mechanisms, or motion systems for expressive or compact applications (animatronics, medical devices, precision robotics, etc.)
- Hands-on experience taking designs from concept to prototype and through iteration
- Comfortable working in a small, fast-moving team - and wearing multiple hats when needed
- Curiosity and creativity - you enjoy building, testing, and making ideas work in the real world
- Practical problem-solving - you can design for today while keeping an eye on scalability
- Collaboration - you work well across disciplines and communicate clearly
- Bias for action - you enjoy early-stage ambiguity and like to figure things out by doing
- Integrity and care - we’re building technology meant to connect with people, so empathy matters
This is an opportunity to join as a founding engineer — shaping not only the hardware architecture but also the DNA of the company. Your work will define how lifelike expression is engineered, and you’ll be part of the earliest team translating emotion into motion.
