Role overview

WHOOP is seeking a Mechanical Engineer II to join the Hardware New Product Introduction (NPI) team in Boston. In this role, you will design and develop innovative rechargeable energy accessories and other hardware solutions that help WHOOP members understand their bodies and optimize their performance. You’ll work in a fast-paced, execution-driven environment where you’ll drive creative mechanical design solutions with technical independence while collaborating across a multidisciplinary team.

Key responsibilities

Own critical mechanical design components for next-generation WHOOP hardware products, taking concepts from design through manufacturing release.
Design, prototype, and test complex mechanical components that integrate with microelectronics while meeting technical, performance, and industrial design specifications.
Develop and present multiple design solutions for novel technical challenges, communicating them clearly to cross-functional teams and thoroughly documenting design processes and specifications.
Generate technical documentation including 3D CAD files, 2D drawings, bills of materials, and engineering change orders according to product development timelines.
Support planning and execution of verification and validation testing, using design of experiments methodologies to improve product quality, performance, and manufacturability.
Communicate engineering requests and changes to international vendors and contract manufacturers throughout the product development cycle.
Conduct engineering root cause analyses to identify and resolve issues, and collaborate with senior engineers to evaluate new technologies and manufacturing methods.

Requirements

Bachelor’s degree in Mechanical Engineering or a related field.
At least two years of experience designing complex mechanical products, ideally in consumer electronics, wearables, or medical devices.
Proficiency with SolidWorks CAD including advanced assemblies, complex surfacing, configuration management, and design for manufacturability feedback.
Hands-on experience operating rapid prototyping tools to create proof-of-concept models.
Strong communication skills and demonstrated ability to work effectively with cross-functional teams and external partners.
Preferred experience includes high-quality consumer electronics or wearable technologies, validation testing methods, statistical analysis tools, high-volume manufacturing processes such as injection molding and sheet metal design, and working in fast-paced or startup environments.

What makes this role worth considering

You’ll be part of WHOOP’s mission-driven hardware team in Boston, working on early-stage product development with urgency and impact. This role offers the opportunity to grow your mechanical engineering skills while contributing to products designed for people who push their limits, with up to 20% travel to contract manufacturers and suppliers globally. WHOOP offers competitive base salary ranging from $110,000 to $150,000, meaningful equity that aligns you with the company’s long-term success, and comprehensive benefits.
