The Role

At WHOOP, we’re on a mission to unlock human performance and healthspan. Our technology empowers users to perform at a higher level through a deeper understanding of their bodies and daily lives.

As a Senior Test Development Engineer, you will play a key role in developing and deploying automated test equipment and tools for mass production, engineering validation, and supplier testing of cutting-edge wearable technology. You'll work closely with cross-functional teams—including Manufacturing, Electrical, Firmware, Mechanical, and Sensor Intelligence—to ensure robust and efficient test solutions throughout the product lifecycle.

RESPONSIBILITIES:

Define overall test strategies and lead design-for-test (DFT) efforts throughout the product development cycle.
Design and develop electrical and control systems for Automated Test Equipment (ATE) used in mass production.
Develop test fixtures for subsystem- or component-level validation during new product introduction (NPI).
Improve test coverage and optimize fixtures to enhance reliability and reduce test cycle time.
Create and maintain procedures for manufacturing testing, including fixture qualification, calibration, maintenance, and Design of Experiments (DOE).
Collaborate with internal engineering teams and external factory partners to support test fixture bring-up, troubleshoot issues, drive yield improvements, and analyze results.
Perform root cause analysis and apply data analytics to implement corrective actions across test systems.
Coordinate contingency plans for high-risk milestones via parallel path development.

QUALIFICATIONS:

Bachelor’s degree in Electrical Engineering or a related technical discipline.
5+ years of experience in electrical design or test system development.
Strong understanding of communication protocols such as UART, I2C, USB, Bluetooth, and NFC.
Proficiency in Altium for schematic design, PCB layout, and simulation.
Proficient in programming languages such as Python, LabVIEW, or C/C++.
Experience working with contract manufacturers (CMs) and joint development manufacturers (JDMs), both domestically and internationally.
Experience in consumer electronics or wearable technology is preferred.
Ability to travel up to 15%, both domestically and internationally.

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 we continue to build a diverse and inclusive environment, we encourage anyone who is interested in this role to apply.
