Senior Electrical Engineer

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

Own the design and development of electrical systems and subsystems for HaloBraid, through pilot builds and production.

Design, prototype, and validate electronics, including circuit design, schematic capture, PCB layout, board bring-up, and debugging.

Develop and integrate sensing, motor control, power distribution, and other electronics for a complex electromechanical system.

Collaborate closely with mechanical, firmware, and systems engineers to make architecture decisions and resolve integration challenges.

Build rigorous test and validation processes, using experiments and data to evaluate performance, reliability, and design tradeoffs.

Design for manufacturability, cost, reliability, and safety, supporting supplier engagement, pilot builds, and production handoff.

Troubleshoot complex hardware issues, identify root causes, and drive solutions from prototype through production.

You have

5+ years of experience designing and developing electronics for physical products, ideally with experience bringing products into production.

Strong fundamentals in analog and digital circuit design, PCB layout, board bring-up, and hardware debugging.

Experience designing electronics for electromechanical systems, including sensors, actuators, motors, and embedded controllers.

Proficiency with electrical design tools and hands-on lab equipment, including oscilloscopes, multimeters, and logic analyzers.

A track record of owning electrical designs from initial concept through prototyping, validation, and production readiness.

Strong system-level judgment and the ability to evaluate tradeoffs across electrical, mechanical, firmware, cost, and reliability requirements.

A rigorous approach to experimentation, troubleshooting, and data-driven decision-making.

Comfort working in a fast-moving hardware environment where designs evolve through testing and iteration.

Desired Skills & Experience (optional but the more, the better)

Experience with motor control, motion systems, or precision robotics.

Experience with embedded firmware development in C/C++ and microcontroller interfaces.

Familiarity with signal processing, feedback control systems, or sensor integration.

Experience with EMC/EMI, electrical safety, and product certification.

Experience with DFM/DFT, PCB assembly, contract manufacturers, and production test development.

Experience developing consumer electronics or other compact, high-reliability electromechanical products.

Experience mentoring engineers or helping establish electrical engineering best practices.

Working Style

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. You can explain complex technical decisions and work effectively across disciplines.
