Principal Mechanical Engineer / Systems Engineer

Understand the full HaloBraid machine and its architecture: identify design, tolerance, assembly, serviceability, and dependency issues, and drive them to resolution.

Personally deliver IC engineering: own a subassembly from 3D CAD through pilot and toward production-ready parts.

Review design work across the team to reduce complexity and raise design standards.

Build strong test/experiment/decision frameworks

Apply DFM/DFA judgment and prepare for pilot builds, supplier engagement, and contract-manufacturer handoff.

Mentor engineers, set practical best practices and standards, and strengthen our engineering culture without becoming process-heavy.

Collaborate with electrical, industrial design, manufacturing, and suppliers.

10+ years, or equivalent depth, in electromechanical product development

Strong mechanical architecture and product-design judgment: you can see the whole system and its tradeoffs.

A track record of delivering designs that made it through pilot or production.

An ability to review CAD and identify design, assembly, and serviceability issues.

A strong experiment / test / decision-making framework

Fluency with control drawings, tolerances, assemblies, and manufacturability.

Taken a product or a major subsystem from prototype toward production.

A desire to mentor other engineers without adding bureaucracy

User-centric. You want to build things people actually use and love.

Low ego, adaptable, collaborative.

A fast, honest iterator. You learn through testing and user feedback, and you follow through on what you suggest.

Driven by the mission. A hard, unsolved robotics problem that gives millions of people their time back is your idea of a good challenge.

A clear communicator
