We are looking for a Senior Mechanical Engineer with 5+ years of experience to own core mechanical subsystems end-to-end at a fast-moving robotics startup building autonomous robots for the AI data center buildout. You'll be a generalist who can do everything from FEA and hand calcs to machining your own parts, working at the heart of the product on the end effector. This is a role for someone who thrives on small teams, loves taking a system from first principles to deployed hardware, and wants true autonomy with real decision-making power and budget access. You'll interface closely with software and electrical teams to build precision electromechanical systems that scale AI infrastructure worldwide.
What will you be doing?
Own the end effector subsystem end-to-end: design, analysis, fabrication, assembly, and validation, the core of the product.
Integrate electromechanical systems including sensing, load cells, and precision linear motion components with tight tolerance requirements.
Drive design decisions with FEA, hand calculations, and trade studies. The cost of mistakes is high, so strong analysis before building is critical.
Interface closely with software and electrical teams to build systems that meet their requirements for sensing and control.
Work hands-on in the in-house machine shop with steel and aluminum-based construction, iterating hardware from months to days.
- 5-10 years of experience designing precision electromechanical systems (robotics, aerospace, or automotive)
- Owned a mechanical subsystem end-to-end at a fast-moving hardware company
- Experience integrating electromechanical systems with sensing (load cells, force sensors) and precision linear motion
- Deep knowledge of precision motion components: ball screws, linear stages, bearings, tolerance stack-ups
- System-level thinker who interfaces cross-functionally with software, electrical, and controls teams
- Proficiency with SolidWorks/CAD, ANSYS/FEA, hand calculations, GD&T, tolerance stack-ups, and CNC machining
- Mechanical engineering degree
- Nice-to-have: startup or small-team experience designing full sub-assemblies with resource constraints
- Nice-to-have: experience designing with steel and aluminum fabrication processes
- Nice-to-have: strong FEA and hand-calc fluency, with designs validated analytically before simulation
