Senior Systems Engineer

About the role

You will own the end-to-end systems engineering lifecycle for WHOOP's next-generation wearable hardware programs, acting as the central technical integrator across Electrical, Mechanical, Firmware, Signal Processing, and Product teams. You will define and shepherd system architecture decisions that balance performance, reliability, and manufacturability while ensuring strict alignment with product requirements and user value. In this leadership role, you will guide critical technical trade-offs, influence product direction, and drive the resolution of complex system-level problems that span the entire development stack. You will mentor engineers by providing hands-on technical guidance and taking on organizational impact as the team scales. Your work will directly shape the future of wearable technology by pushing the boundaries of what is possible in health and performance sensing. You will translate abstract product goals into concrete system specifications and validation strategies that de-risk development and accelerate delivery. This is a unique opportunity for an electrical engineering expert who thrives in fast-paced, cross-functional environments and is passionate about building hardware that changes how people understand their bodies.
