Senior Electomechanical Engineer

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.

WHOOP is hiring an Electromechanical Engineer (Manufacturing Test) to develop the electrical fixtures and systems that enable reliable, scalable testing of WHOOP products throughout product development and mass production. You will develop board-level and assembly-level test fixtures, fixture wiring, and electrical interfaces that connect WHOOP products with automated test equipment and instrumentation. Working closely with Hardware Test, Mechanical, Electrical, Firmware, and Manufacturing Engineering teams and our contract manufacturing partners, you'll help deliver robust production test solutions.

• Develop electrical and electromechanical fixtures for manufacturing test applications, from early engineering prototypes through mass-production solutions
• Develop board-level test fixtures and interfaces for PCBAs, including pogo-pin and bed-of-nails systems, test-point interfaces, interconnects, signal routing, power delivery, and integration with automated test equipment
• Define requirements for fixture electronics and interface hardware, and review designs developed by internal and external partners for compatibility with product and test requirements
• Design and document fixture electrical systems including wiring, harnesses, connectors, signal routing, instrumentation, and assembly-level electrical interfaces
• Collaborate with Hardware Test, Electrical, and Mechanical Engineering to develop reliable fixture solutions considering signal integrity, measurement quality, repeatability, robustness, serviceability, and cost
• Partner with contract manufacturers throughout fixture development, including design reviews, sourcing, fabrication, assembly, qualification, and production deployment
• Build, bring up, and debug electrical fixtures using schematics, instrumentation, software tools, and structured root-cause analysis; support fixture qualification and production troubleshooting
• Create and maintain accurate wiring diagrams, BOMs, assembly instructions, and other production documentation through established PLM and change-control processes
• Own scoped fixture-development projects or work streams within larger product programs, communicating progress and identifying technical risks and dependencies

• Bachelor's degree in Electrical Engineering, Electromechanical Engineering, Mechatronics, or a related technical discipline
• 2+ years of experience developing electrical test fixtures, automated test equipment, electronics, automation systems, or similar electromechanical hardware
• Strong electrical fundamentals including circuit analysis, power distribution, grounding, signal integrity, and common analog and digital interfaces
• Experience developing, integrating, or debugging board-level test solutions; experience with pogo-pin, bed-of-nails, ICT, functional test, or other PCBA test systems is preferred but not required
• Experience defining fixture-electronics requirements and reviewing schematics and PCBAs for integration with test equipment and DUTs
• Experience designing and debugging wiring, harnesses, connectors, and electrical interfaces for test or automation equipment
• Hands-on experience with laboratory instrumentation such as digital multimeters, oscilloscopes, power supplies, electronic loads, and data-acquisition equipment
• Familiarity with communication protocols such as UART, I²C, SPI, USB, or similar hardware interfaces
• Understanding of basic metrology concepts including measurement accuracy, repeatability, calibration, and common sources of measurement error
• Ability to navigate and review…
