Mechanical Design Engineer

We don't buy our factory off the shelf - we design and build the machines, fixtures, and tooling that make automated harness production possible. That's what this role does.

The role

This is a role where you own whole machines, not just parts. You'll design the mechanical systems that build harnesses - mechanisms, end effectors, fixtures, tooling - and then integrate motion, controls, and our vision/robotics systems into a machine that actually runs on the floor. You'll take problems from a blank Onshape document through prototyping, bring-up, and debugging, working shoulder-to-shoulder with robotics, controls, and the technicians running the line.

We're hiring for hunger, fundamentals, and a track record of building real things - not years on a resume. Whether you're a recent grad who's been building robots in your garage or a seasoned machine builder who wants more ownership, what matters is that you've actually built things and want to own machines end-to-end. Everyone here gets real mentorship and a steep growth curve.

Problems you'll get to solve

A few of the problems you'd actually work on

-

Design machines and end effectors that handle limp, variable wire and tiny connectors: the parts the industry still says can't be automated

-

Build fixtures and tooling that turn fiddly manual steps (routing, strain relief, seating) into fast, repeatable operations

-

Integrate mechanical, motion, and vision into a machine that runs reliably on the floor, not just on the bench

-

Hit tight tolerances and cycle times while keeping machines buildable, serviceable, and cheap enough to replicate

-

Get from a blank Onshape doc to a working, production-grade machine fast, then make the next one better

What you'll do

-

Design mechanisms, end effectors, fixtures, and tooling for the automated line in Onshape

-

Own machines end-to-end: concept → CAD → prototype → bring-up → debugging → running in production

-

Integrate your mechanical designs with motion, actuators, controls, and our vision/robotics systems into working machines

-

Prototype fast with 3D printing, machining, and off-the-shelf parts; iterate on real hardware

-

Apply DFM/DFA and sound tolerancing; spec materials, hardware, and fits

-

Source parts and work with machine shops and vendors

-

Be on the floor when your machine runs - measure cycle time, yield, and reliability, and make it better

You are

-

A mechanical engineer at any level who has built real things - robots, machines, mechanisms, projects (school, internships, FRC/FSAE, personal builds, or years of professional machine design all count)

-

Hands-on and resourceful: happy in CAD and at a workbench with a wrench

-

Hungry for ownership and able to learn fast

-

Comfortable with ambiguity and rapid iteration

-

Excited to work across mechanical, controls, and robotics rather than stay in one lane

-

Happier when the machine is running on the floor than when the CAD looks clean

Minimum qualifications

-

Mechanical engineering degree or equivalent hands-on experience - open to all experience levels, from new grad to seasoned

-

Demonstrated experience designing and building real mechanisms or machines (projects, internships, competitions, personal builds, or professional work)

-

Proficiency in Onshape or another parametric CAD tool (you can pick up Onshape fast if you know SolidWorks/Fusion)

-

Solid mechanical fundamentals: mechanism design, tolerancing/GD&T basics, materials, fasteners

-

Comfortable working on-site in Austin, TX with physical hardware (or relocating there - see relocation note above)

-

Legally authorized to work in the U.S. or Canada

Nice to have

-

Onshape specifically

-

Automation, robotics, or special-purpose machine building

-
