You thrive in a fast-paced, execution-driven setting and can drive creative mechanical design solutions with independence and sound technical judgement. You’ll work alongside a multidisciplinary team of engineers and designers to help bring innovative concepts to life, supporting prototyping, mechanical design, and testing efforts. 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. This is a great opportunity for an engineer with a solid technical foundation to grow their skills in a dynamic, fast-paced environment while contributing to impactful projects in early-stage product development.

  • Develop and present multiple design solutions for novel and complex technical challenges, articulating them clearly to cross-functional teams and documenting design process and specifications thoroughly.
  • 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 engineering requests and changes to vendors and contract manufacturers as the product development cycle progresses
  • Support planning and execution of verification and validation plans, leveraging design of experiments (DOE) methodologies to drive understanding, uncover insights, and deliver actionable results that enhance product quality, performance, and manufacturability.
  • Support and perform thorough engineering root cause analyses to identify and resolve issues
  • Collaborate with senior engineers to evaluate new technologies and manufacturing methods.
  • Up to 20% travel to contract manufacturers and suppliers internationally
  • QUALIFICATIONS:
  • Bachelor’s degree in Mechanical Engineering or related field.
  • 2+ years of experience in the design of complex mechanical products, preferably for consumer electronics, wearables, or medical devices.
  • Experience with SolidWorks CAD best practices, including advanced assemblies, complex surfacing, configuration management and applying DFx feedback.
  • Hands-on experience in operating and maintaining rapid prototyping tools to craft proof-of-concept models.
  • Strong communication skills and comfort working with cross-functional teams and external partners.
  • Experience in high-quality consumer electronics or wearable technologies preferred.
  • Familiarity with validation testing methods and statistical analysis tools preferred.
  • Experience with high-volume manufacturing processes (e.g., injection molding, sheet metal design, metal injection molding) and manual assembly preferred.
