About the Job

Requirements

  • A bachelor's degree or higher in Electrical Engineering or a related technical field, or equivalent practical experience.
  • At least 8 years of relevant electrical engineering experience, with demonstrated technical leadership and ownership of complex electrical or embedded systems.
  • Deep electrical engineering fundamentals across mixed-signal circuit design, power management, digital interfaces, signal integrity, and debugging of highly integrated systems.
  • Exceptional hands-on test, characterization, and debugging skills, with the ability to use experimentation and data to understand complex system behavior and drive meaningful design changes.
  • Strong experience with schematic capture and PCB design or review using ECAD tools such as Altium or equivalent.
  • Demonstrated ability to lead ambiguous, cross-functional technical investigations, mentor other engineers, and drive complex engineering decisions to closure.
  • Strong commitment to embracing and leveraging AI tools in day-to-day tasks, ensuring AI-assisted work aligns with the same high-quality standards as personal contributions.

Responsibilities

  • Lead electrical system characterization and technical investigations, developing a deep understanding of system behavior across power, mixed-signal circuitry, digital interfaces, sensing, noise, timing, and other critical performance areas.
  • Define and execute experiments that efficiently answer complex engineering questions, isolate variables, identify root causes, and expose interactions across electrical subsystems and the broader product.
  • Translate characterization results and system insights into actionable architecture, schematic, component, layout, firmware, and system-level design improvements.
  • Drive resolution of complex electrical and cross-functional technical issues using first-principles analysis, bench measurements, device telemetry, and structured experimentation to move from symptoms to root cause.
  • Build scalable characterization and analysis methods using Python, MATLAB, or equivalent tools to improve test coverage, automate analysis, identify trends, and accelerate engineering learning cycles.
  • Partner with Electrical, Firmware, Mechanical, Systems, Software, and Manufacturing teams to define requirements, evaluate tradeoffs, and improve end-to-end system performance, reliability, and manufacturability.
  • Manage and develop a small team of electrical engineers by setting technical priorities, creating clear ownership, providing mentorship and design review, and helping engineers grow while maintaining a high bar for technical execution.
  • Remain hands-on with schematic and circuit design, prototype bring-up, debugging, and design iteration, directly contributing to critical design changes where needed.
  • Establish rigorous validation approaches and success criteria that build confidence in electrical system performance across operating conditions, unit-to-unit variation, and product use cases.
  • Travel up to 15% domestically and internationally to collaborate with partners, suppliers, and contract manufacturers.

About the Company

Whoop

Makes screenless trackers for sleep and recovery

Whoop makes a screenless wristband that tracks sleep, exercise strain, and recovery around the clock, and it sells the band to athletes and everyday users only as part of a membership. In 2020, the PGA Tour gave Whoop straps to players and caddies after one golfer's data flagged his COVID-19 infection before he had symptoms. The band records heart rate, the variation between beats, skin temperature, and blood oxygen, and the app turns those readings into daily scores and advice on when to push or rest. Members pay a yearly fee that covers the band, with pricier tiers adding heart-rhythm and blood pressure readings, and Whoop also sells blood tests. Whoop was founded in 2012 at Harvard's startup lab and is based in Boston.
