The posting

Halo is a technology company building the future of haircare for all textures. We create category-defining products built for the complexities others overlook.

We're building HaloBraid, the world's first braid-assist device. It helps stylists finish braids five times faster, flawlessly and gently. This is one of the hardest unsolved problems in robotics, applied to a $270B salon services industry, and integrating computer vision, compliant fiber manipulation, and novel mechanisms.

Billions of hours are spent braiding hair each year; HaloBraid gives that time back. We're moving from R&D into deployment with salons, and we're backed by leading investors.

YOU WILL

- 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.

YOU HAVE

- 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

DESIRED SKILLS (OPTIONAL)

- BOM ownership

- Supplier searches with technical and cost recommendations: CM / supplier interface experience.

- Product roadmap input

- Production-transfer experience.

- People-management experience.

- Robotics or mechatronics experience.

- Production embedded / electrical interface awareness.

WHO YOU ARE

- 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

BENEFITS OF WORKING WITH US

- 100% medical premium coverage, comprehensive dental and vision benefits.

- Meaningful equity.

- 12 company holidays and unlimited PTO.

- Free parking onsite.

ONSITE WORK

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
