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. BENEFITS OF WORKING WITH US - 100% medical premium coverage, comprehensive dental and vision benefits. - Meaningful equity. - 12 company holidays and unlimited PTO. - Onsite parking ONSITE WORK This is an onsite position at our office/lab in Cambridge, MA. You must have authorization to work in the US. DON'T MEET EVERY REQUIREMENT?
