Redwood City, California, United States Stealth Robotics Startup Full time

About us

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 mechatronics 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.

What you'll do

  • 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

What you bring

  • 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

What we value

  • 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

Why this matters

This is an opportunity to join as a founding member — 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.

Compensation

Competitive salary + meaningful equity

We're early - your impact will be direct and visible

If you're driven by curiosity, care about human-centered robotics, and want to build something that's never existed before, we'd love to hear from you.
