About Bracket Bot

Bracket Bot is building low-cost, general-purpose robots that developers can program and deploy in days.

We’re transforming the world’s ~50 million software engineers into robotics engineers by building a full-stack platform—hardware, software, and ML—designed from first principles for performance, usability, and cost. Low expense is a design goal, not a constraint.

By transforming commodity, mass-manufactured components through disciplined engineering, we deliver robots that are reliable, high-performance, and inexpensive to build and operate. We believe fewer than 1,000 engineers globally can reason about robotics as a true vertically-integrated system, and we’re assembling a small team of them to build an accessible, developer-first robotics platform.

We’re backed by an amazing group of investors, co-led by Fifty Years (Scott Phoenix) and BoxGroup, with participation from Betaworks and Pace Capital, plus standout angels including Logan Kilpatrick (Google AI), Mohith Mothukuri (Physical Intelligence), and Guillermo Rauch (CEO of Vercel).

Bracket Bot is building a low-expense, high-performance robotics platform ready for real-world deployment.

About the role

We’re building the next version of our robot. We need a Founding Mechanical Engineer to own mechanical and electromechanical design from day one.

You’ll be responsible for designing the robot’s physical architecture—mechanisms, structure, packaging, and integration—while working closely with EE and robotics software to ship complete, working systems.

This is a hands-on builder role: you’ll prototype, assemble, debug, and iterate quickly alongside the team.

What you’ll do

•

Lead mechanical design for next-gen robot hardware

•

Design electromechanical systems:

•

Motors, gears, encoders

•

BLDC motors, FOC interfaces

•

Work hands-on with assembly and iteration

•

Collaborate tightly with EE and robotics SWE

What we’re looking for

•

Strong mechanical engineering fundamentals

•

Experience building electromechanical systems

•

High ownership + hands-on “builder” mentality

•

Strong candidates often have backgrounds like:

•

FSAE / Motorsports

•

Robotics teams / research labs

•

Robot arms, humanoids, or complex mechanisms

Nice to Have

•

Experience with:

•

Hardware prototyping, 3D printing, CNC machining

•

SOLIDWORKS and/or Onshape

•

DFMA / DFM / DFA

•

Thermal constraints (airflow, conduction, heatsinks, fan integration)

•

Cable routing + strain relief + connectorization

•

Tolerance stack-ups / GD&T

•

Familiarity with:

•

Control loops at a conceptual level (you don’t need to be a controls engineer)

•

Sensors (IMUs, force/torque, encoders) and sensor mounting best practices

•

Comfort working cross-functionally with EE:

•

PCB placement constraints

•

harness / routing / grounding considerations

•

Prior robotics startup experience (or a track record of shipping hardware fast)

Important notes

•

This is a founding team role: you’ll have significant influence over mechanical architecture and long-term standards.

•

You will be expected to do hands-on assembly and debugging, especially early on.

•

We care more about shipping + iteration speed than credentials.

•

In-person collaboration matters — we move fastest as a tightly integrated hardware & software team.

•

You should be excited about building developer-first robots — not just “a robot”.
