Mechanical Engineer

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

WHOOP is looking for a Staff Mechanical Engineer to lead critical design, validation, and development execution 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.

• Complete technical ownership (at system level) of a next generation product from design concept to manufacturing release, ensuring performance, reliability, cost, and schedule targets are met
• Lead mechanical design, analysis and development of mechanical components around micro‑electronics, and exact industrial design visions and specifications, product requirements, and manufacturing constraints
• Create Solid Works 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 and collaborate effectively across cross‑functional teams to align requirements, drive decisions, and resolve issues quickly
• Drive organized, end‑to‑end DFM coordination across multiple vendors and manufacturing methods, aligning requirements, timelines, and technical decisions to deliver scalable, high‑yield production
• Partner with suppliers to explore and carry multiple material and design concepts in parallel
• 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

• BS or MS in Mechanical Engineering or a related field
• 10+ years of experience in the design, documentation and validation of complex mechanical parts for medium to high volume consumer electronics
