About The Position

At WHOOP, we're on a mission to unlock human performance and healthspan. WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives. As a Staff Electrical Engineer on the WHOOP Hardware team, you will lead the architecture, design, and delivery of complex embedded signal acquisition and transduction subsystems within highly integrated human performance products. You will work closely with Electrical, Mechanical, Firmware, Manufacturing, Supply Chain, and Software teams to translate system-level requirements into robust, production-ready hardware. WHOOP products integrate wireless connectivity and multiple sensing modalities in a small, low-power form factor, requiring exceptional mixed-signal design and signal-chain rigor. This role emphasizes end-to-end signal-chain performanceâincluding dynamic range, timing/synchronization, noise, latency, and fidelityâplus disciplined hardware/firmware/algorithm co-design. You will be a hardware technical lead who is fluent in DSP fundamentals and data-driven debug, able to define requirements, influence architecture choices, and partner effectively through bring-up, tuning, and validation.

Requirements

BS or higher in Electrical Engineering (or related); 7+ years in relevant hardware engineering roles.
Proven ownership of embedded electronics from architecture through schematic, PCB layout/review (e.g. via Altium), bring-up, and production release (e.g. via Arena).
Strong circuit design fundamentals spanning mixed-signal design, power, and digital interfaces in low-power systems.
Demonstrated success delivering low-noise, interference-resilient signal chains, including noise budgeting, grounding/isolation, coupling mitigation, and EMI/EMC robustness.
Experience defining sampling and timing/synchronization requirements for embedded acquisition systems (clock domains, jitter sensitivity, multi-rate considerations).
Hands-on debug and characterization expertise using standard lab instrumentation (scope, logic analyzer, spectrum analyzer, etc.).
Effective cross-functional partner to firmware and modeling/DSP teams: able to translate performance goals into hardware requirements, interface/observability hooks, and validation plans.
Working fluency in DSP fundamentals (sampling/aliasing, filtering concepts, precision/fixed-point tradeoffs) sufficient to drive hardware architecture choices and end-to-end performance debugging.
Data-driven validation mindset and tooling experience (Python/MATLAB or equivalent) to analyze captured datasets, generate test vectors, and support automated characterization/regression.

Nice To Haves

Experience building miniaturized wearables or other highly integrated wireless consumer devices with challenging interference/coexistence constraints desired.
Prior experience with latency-sensitive, real-time streaming data paths in low-power devices, including cross-functional performance tuning across hardware/firmware/algorithms desired.

Responsibilities

Lead the architecture and delivery of embedded signal acquisition/transduction subsystems; own electrical specs, performance metrics, and execution plan.
Design low-power, low-noise mixed-signal hardware from component selection through system integration, including schematic capture and PCB layout/review.
Drive signal and power integrity strategy (grounding, isolation, coupling mitigation) and EMI/EMC robustness in a tightly integrated wireless wearable.
Define clocking, timing, and synchronization across domains; set and verify sampling and latency budgets.
Translate system and algorithm goals into measurable electrical requirements and verification plans (dynamic range/noise, bandwidth, power modes, calibration).
Partner with firmware and algorithm/DSP teams on latency-sensitive, real-time streaming data paths and interface contracts (buffering, timestamps, observability).
Lead bring-up, debug, and characterization using lab instrumentation; correlate bench behavior with device telemetry and end-to-end performance metrics.
Build analysis/validation workflows (Python/MATLAB) using test vectors, golden datasets, and automated characterization/regression to support tuning and production readiness.
Travel up to 15% domestically and internationally to partners, suppliers, and contract.
