Mechanical Engineer I — Early-Stage Wearable Hardware

WHOOP; Boston (MA); On-site; USD 70,000 - 95,000; Full time

Job summary

WHOOP is seeking a Mechanical Engineer to design and develop early-stage hardware, moving concepts from prototype toward manufacturable products. You will contribute to mechanical design around microelectronics and collaborate with a multidisciplinary team to bring innovative concepts to life.

You’ll prototype with 3D printing and CNC, run validations, and apply DOE methodologies to improve quality, performance, and manufacturability while engaging cross-functional teams.

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.
• 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.

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.
