Senior Manufacturing Engineer: Scale-Up & Automation

WHOOP; Boston (MA); On-site; USD 150,000 - 195,000; Full time

Job summary

WHOOP in Boston, MA is seeking a Senior Manufacturing Engineer to translate product design into scalable manufacturing, shaping assembly strategies, fixtures, tooling, and processes. You will collaborate with Product Design, Mechanical, Electrical, and Quality teams to identify risks early and enable high-volume production.

The role requires hands-on expertise in GD&T, DFX, DFx, and fixture design, with 5+ years in manufacturing and a track record in small electromechanical devices.

Qualifications

• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or a related technical field.
• 5+ years of manufacturing engineering experience supporting product development and moderate- to high-volume manufacturing.
• Ability to operate independently in fast-paced product development and manufacturing environments with limited technical oversight.
• Strong experience applying DFM, DFA, and DFX principles during product development, with demonstrated ability to influence product designs for manufacturing.
• Strong proficiency in SolidWorks, including detailed mechanical design, assemblies, drawings, and fixture design best practices.
• Strong knowledge of GD&T, datum structures, tolerance analysis, tolerance stack-ups, and dimensional inspection methods.
• Experience developing and qualifying manufacturing processes for small electromechanical or battery-powered electronic products.
• Experience with manufacturing technologies including adhesives, heat staking, injection-molded plastics, and automated and manual assembly.

Responsibilities

• Partner closely with Product Design and Mechanical Engineering throughout product development to drive DFM, DFA, and DFX, identifying manufacturing risks and influencing product designs for assembly, quality, scalability, automation, and cost.
• Develop manufacturing concepts and assembly strategies from early prototypes through production, translating product requirements into practical manufacturing processes, tooling, and equipment.
• Design and develop fixtures, tooling, nests, gauges, and manufacturing aids used for assembly, alignment, bonding, welding, inspection, and test.
• Own fixture and tooling development from concept through detailed design, tolerance analysis, fabrication, debugging, qualification, and release to production.
• Apply GD&T, tolerance analysis, datum strategies, and mechanical design principles to ensure product and fixture designs support repeatable manufacturing and measurement.
• Work with product engineering teams to evaluate component interfaces, assembly sequences, joining methods, tolerance stack-ups, and other design characteristics that impact manufacturability.
• Develop and qualify manufacturing processes including adhesive bonding, heat staking, mechanical assembly, and other processes used in small consumer electronic devices.
• Define critical process parameters, process windows, acceptance criteria, and controls to ensure manufacturing processes consistently meet product requirements.
• Evaluate manual and automated assembly approaches and develop fixture and equipment concepts that enable appropriate levels of automation.
• Use DOEs, process characterization, capability analysis, and failure analysis to validate manufacturing designs and optimize process performance.
• Troubleshoot complex product, fixture, and process interactions during development builds and production ramp, driving issues to root cause and implementing robust engineering solutions.
• Collaborate directly with contract manufacturers, equipment vendors, and tooling suppliers to develop, review, debug, and qualify manufacturing solutions.
• Provide hands-on technical support during prototype builds, engineering validation, process qualification, and production ramp.
• Travel domestically and internationally up to 25% to support development builds, tooling and equipment qualification, and production ramp.
