Responsibilities
- Drive mechanical fixture development for complex manufacturing test applications from early concept through validation, production deployment, and sustaining, partnering closely with contract manufacturers on design and execution
- Translate test and product requirements into robust fixture designs, making appropriate tradeoffs between performance, repeatability, complexity, cost, cycle time, and maintainability
- Design fixtures directly where appropriate and provide technical direction and design review for solutions co-developed with manufacturing partners
- Apply strong mechanical engineering principles including tolerance analysis, GD&T, material selection, datum strategy, alignment, DFM, and manufacturing process selection to review and validate fixture designs
- Lead fixture debugging and root-cause investigations, using structured problem solving and data to resolve issues related to tolerance, alignment, wear, loading, repeatability, and fixture performance
- Collaborate across engineering teams to define fixture requirements and drive improvements to fixture design, qualification, maintenance, and development practices
- WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives.
- WHOOP is hiring a Senior Mechanical Engineer (Manufacturing Test) to develop the mechanical test fixtures and systems that enable reliable, scalable testing of WHOOP products throughout product development and mass production.
- You will drive fixture development from early concepts through production deployment, co-developing solutions with our contract manufacturing partners and translating test requirements into robust mechanical designs.

- Working knowledge of electrical systems, wiring, instrumentation, and PCBAs sufficient to integrate and debug electromechanical test fixtures
- Ability to travel up to 15%, both domestically and internationally
- Strong mechanical design fundamentals including tolerance analysis, GD&T, material selection, manufacturing processes, fastening methods, and DFM
- Advanced proficiency with 3D CAD and engineering drawings; SolidWorks experience is strongly preferred
- Experience developing mechanical fixtures or equipment from requirements through prototype, validation, release, and production support
- Experience co-developing mechanical systems with contract manufacturers, suppliers, or external engineering partners, including technical direction and design review
- Strong mechanical debugging and root-cause analysis skills, with experience using data to characterize and improve fixture performance
- Experience using manufacturing data and statistical methods to evaluate repeatability, variation, and fixture capability; familiarity with SPC is preferred
- Strong project ownership, communication, and cross-functional collaboration skills, with the ability to independently drive complex fixture-development projects
- Strong commitment to leveraging AI tools in day-to-day tasks, ensuring AI-assisted work aligns with the same high-quality standards as personal contributions
Nice to have
- SolidWorks experience is strongly preferred
- Advanced proficiency with 3D CAD and engineering drawings
- Experience using manufacturing data and statistical methods to evaluate repeatability, variation, and fixture capability
- familiarity with SPC is preferred
- Familiarity with Python or other scripting languages for engineering analysis, automation, or debugging is a plus
