Job description

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.

As a Manufacturing Design Engineer II on the NPI team, you will develop and troubleshoot manufacturing processes, support prototype and pre‑production builds (prototype, EVT, DVT, PVT), and ensure high quality and efficiency from early development through mass production. You will partner closely with Mechanical, Electrical, Supply Chain, and external manufacturing teams to deliver DFX feedback and drive designs that are manufacturable, scalable through automation, and optimized for performance, cost, and speed at high volume. You bring experience in DFX, process design and validation, and fixture development, along with a strong interest in supporting build execution in factory environments.

RESPONSIBILITIES:

• Drive manufacturing technical readiness across NPI builds (prototype, EVT, DVT, PVT) through process development, documentation, and validation
• Partner with internal engineering teams and contract manufacturing partners to deliver DFX feedback, with a focus on highly automated assembly systems
• Support in‑house prototype build preparation and execution, including development of assembly procedures, fixtures, and build documentation
• Coordinate with factory teams and manufacturing partners on the design, build, and qualification of fixtures, equipment, and highly automated manufacturing processes to support scalable production
• Develop, maintain, and release manufacturing documentation, including drawings, SOPs, PFMEAs, work instructions, qualification protocols, and root cause reports
• Define and execute DOEs, conduct failure analysis, and apply structured problem‑solving methodologies (DMAIC, 8D) to identify root causes and drive corrective and preventive actions
• Define manufacturing requirements for automation and MES integration, including part traceability and data collection to support quality, yield, and process control
• Ensure manufacturing processes meet product specifications and quality requirements through data‑driven process controls, verification, and analysis
• Communicate manufacturing status, risks, issues, and build readiness across cross‑functional stakeholders
• Support parallel‑path and contingency efforts for high‑risk milestones and build phases
• Willingness to travel up to 25% globally

QUALIFICATIONS:

• Bachelor’s degree in Mechanical, Manufacturing, Electrical Engineering, or a related technical field
• 3+ years of manufacturing engineering experience supporting moderate to high‑volume consumer electronics products with an emphasis on automated assembly systems
• Working knowledge of injection molding, metals, ceramics, and related materials used in precision electromechanical assemblies
• Hands‑on experience with adhesive bonding, heat staking, glue dispensing, and battery assembly
• Experience developing, validating, and ramping manufacturing processes across manual and highly automated assembly operations
• Solid understanding of tolerance stack‑up analysis for high‑volume manufacturing and applying appropriate dimensioning strategies to evaluate process capability
• Familiarity with MES systems and manufacturing data infrastructure, including part traceability, process data collection, and statistical process control (SPC)
• Demonstrated ability to qualify manufacturing processes, troubleshoot issues on the factory floor, and drive corrective actions to closure
• Proficiency in SolidWorks with best practices for fixture, tooling, and equipment design
• Strong organizational and prioritization skills in a fast‑paced, cross‑functional environment
• Experience working effectively with internal engineering teams and external manufacturing partners within a CM/JDM operating model

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.
