• Lead mechanical troubleshooting and root cause analysis for product and process issues.

• Review and optimize designs for manufacturability (DFM), assembly (DFA), and reliability.

• Create and evaluate 2D drawings, identifying critical dimensions and key tolerances.

What You Bring

• BS or MS in Mechanical Engineering (or related field) and 5+ years of experience.

• Proven design experience with wearable consumer electronics, ideally with a focus on user comfort (earbud experience a plus).

• Experience designing products from prototype to mass production.

• Advanced proficiency with parametric 3D CAD tools (SolidWorks preferred) including complex surfacing.

• Strong understanding of tolerance analysis (max/min and RSS).

• Deep knowledge of DFM principles across injection molding, stamping, and rapid prototyping.

• Experience collaborating with global contract manufacturers to bring consumer products to market.

Location & Travel

• Hybrid role based in New York, NY or Marlborough, MA
