WHOOP is looking for a Senior Mechanical Engineer to lead critical design, validation, and development for next generation biometric wearable products. You are a proactive, highly organized engineer with strong problem-solving skills and a sharp eye for detail. You thrive in a fast-paced, execution-driven setting and can drive creative mechanical design solutions with independence and sound technical judgement. You will mentor junior mechanical engineers and collaborate with cross-functional stakeholders (Electrical Engineering, Embedded Engineering, Manufacturing, Product, and Program Management). You will work closely with our suppliers and contract manufacturers around the world to execute engineering validation builds with a focus on high quality deliverables, sharp engineering risk management, clear technical communication upwards and externally, and commitment to product excellence. WHOOP operates with urgency because our mission demands it. We build products for people who push their limits—and we hold ourselves to the same standard. If you’re energized by complex challenges, cross-functional collaboration, and the opportunity to ship hardware at scale, this role will push you—and reward you.

  • Create SolidWorks CAD models to bring up design concepts that enable simulation exercises, prototyping, and mass production qualification 

  • Generate technical documentation such as 3D files, 2D drawings, bills of material (BOM’s), and Engineering Change Orders (ECO’s) following product development cycle timeline

  • Communicate engineering changes to vendors and contract manufacturers as the product development cycle progresses 

  • Design testing protocols and validation plans, managing testing processes

  • Perform thorough engineering root cause analyses to identify and resolve issues

  • Mentorship, engineering best practices

  • Willingness to travel internationally up to 20% of the time

QUALIFICATIONS:

  • BS or MS in Mechanical Engineering or a related field

  • 4+ years of experience in the design, documentation and validation of complex mechanical parts for medium to high volume consumer electronics

  • 4+ years SolidWorks CAD experience with best practices for part design/ feature architecture, advanced assemblies, complex configuration management and integrating DFx feedback efficiently

  • 2+ years working with Tier 1 and 2 contract manufacturers in Asia and North America

  • Extensive experience in mechanical design concepts and the manufacture of products utilizing high volume, automated manufacturing processes as well as manual assembly

  • Well-versed in design, prototyping, and evaluation of advanced injection molded plastic components, die castings, metal injection molding, packaging, and material selection

  • Strong organization and communication skills and the ability to work well within teams in a fast-paced environment

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.
