At WHOOP, we're on a mission to unlock human performance. 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 Mechanical Engineer on the Hardware Advanced Development Team at WHOOP, you will contribute to 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. You’ll work alongside a multidisciplinary team of engineers and designers to help bring innovative concepts to life, supporting prototyping, mechanical design, and testing efforts. This is a great opportunity for an engineer with a solid technical foundation to grow their skills in a dynamic, fast-paced environment while contributing to impactful projects in early-stage product development.

RESPONSIBILITIES:

  • Contribute to mechanical design and development of early-stage projects to shape the future of WHOOP hardware.

  • Design, prototype, and test 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.

  • Support the design and execution of 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 build confidence in NPI readiness.

  • Operate and maintain in-house prototyping tools, including 3D printers and CNC machines, to create proof-of-concept prototypes and support early-stage development.

  • Collaborate with senior engineers to evaluate new technologies and manufacturing methods.

  • Up to 10% travel to contract manufacturers and suppliers.

QUALIFICATIONS:

  • Bachelor’s degree in Mechanical Engineering or related field.

  • 0-3 years of experience in the design of complex mechanical products, preferably for consumer electronics, wearables, or medical devices.

  • Experience with SolidWorks, or transferable CAD program

  • Hands-on experience with rapid prototyping tools to craft proof-of-concept models.

  • Strong communication skills and comfort working on cross-functional teams.

  • Working understanding of SolidWorks best practices, including advanced assemblies, surfacing, configuration management and applying DFx feedback.

  • Familiarity with validation testing methods and statistical analysis tools.

  • Experience with high-volume manufacturing processes (e.g., injection molding, sheet metal design, metal injection molding) and manual assembly.

  • Prior experience in high-quality consumer electronics or wearable technologies is preferred.
