Senior Mechanical Engineer (Advanced Development)

At WHOOP, we're on a mission to unlock human performance and health span. WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives. By delivering actionable insights and innovative hardware, WHOOP helps members achieve their goals and push the boundaries of human potential. As a Senior Mechanical Engineer at WHOOP, you will play a pivotal role in advancing the design and development of WHOOP’s innovative hardware solutions. You will push the boundaries of technology by driving product innovation from conceptual prototypes to manufacturing-ready designs. With a strong foundation in prototyping, mechanical fabrication, and advanced experimentation techniques, you will directly influence the future of WHOOP hardware and its ability to unlock human performance. The ideal candidate is a leader in early-stage new product development that draws from a foundation of experience from established electro-mechanical product companies. In this role, you will have the opportunity to shape cutting-edge hardware solutions while growing your technical expertise and leadership skills in a dynamic, fast-paced environment. Lead the mechanical design and development of advanced projects to shape the future of WHOOP hardware. Design and analyze complex mechanical components around microelectronics, meeting stringent technical, performance, and industrial design requirements to guide projects from concept through manufacturing release. Develop and present multiple design solutions for novel and complex technical challenges, articulating them clearly to cross-functional teams and documenting design process and specifications thoroughly. Design and execute comprehensive testing and validation plans, employing advanced design of experiments (DOE) methodologies to drive understanding, uncover insights, and deliver actionable results that enhance product quality, performance, and manufacturability. Partner with the Hardware Product Team to lead engineering evaluation of new technologies, addressing risks that ensure the success of future NPI programs. Operate and maintain in-house prototyping tools, including CNC machines, to create proof-of-concept prototypes and support early-stage development. Mentor colleagues by demonstrating exemplary engineering analysis, clear communication, and full lifecycle project ownership. Up to 10% travel internationally to contract manufacturers and suppliers. Bachelor’s degree in Mechanical Engineering or related field. 5+ years of experience in the design and product release of complex mechanical products for medium to high volume consumer electronics. Experience with SolidWorks CAD best practices, including advanced assemblies, complex surfacing, configuration management and applying DFx feedback. Proven expertise in operating and maintaining rapid prototyping machinery to craft proof-of-concept models. Excellent communication skills with the confidence to distill complex technical concepts into language that can be understood by a wide variety of teams. Prior experience in high-quality consumer electronics or wearable technologies preferred. Familiarity with advanced testing methods and statistical analysis tools preferred. Experience with optical sensing technologies and/or other projects in the physiological monitoring space preferred. Some experience with high-volume manufacturing processes (e.g., injection molding, die casting, metal injection molding) and manual assembly preferred. Strong project management skills in fast-paced, cross-functional environments preferred. This role is based in the WHOOP office located in Boston, MA. The successful candidate must be prepared to relocate if necessary to work out of the Boston, MA office. Interested in the role, but don’t meet every qualification? We encourage you to still apply! At WHOOP, we believe there is much more to a candidate than what is written on paper, and we value character as much as experience. As
