Mechanical Engineer

About the role

Proxxi Technology Corporation is seeking a hands‑on Mechanical Engineer to own all mechanical aspects of its wearable safety devices. This is a solo, full‑time contributor role responsible for everything from enclosure design to tooling and manufacturing, working closely with the CTO, Head of Manufacturing and an external industrial design contractor.

Key responsibilities

• Translate industrial‑design concepts into production‑ready CAD models, defining parting lines, draft angles, wall thickness, ribs, bosses and snap‑fits.
• Perform tolerance stack‑up analysis and ensure IP67 waterproofing using gaskets, O‑rings, adhesives or ultrasonic welding.
• Create mold tool drawings, specify gate locations, ejector layouts, cooling channels and cosmetic finishes.
• Lead DFM reviews, GD&T application, assembly sequence definition and error‑proofing.
• Design jigs, fixtures and test rigs for assembly, testing and quality control.
• Develop manufacturing processes, manage mold maintenance, tool‑life and yield improvement.
• Support NPI at contract manufacturers, including EVT/DVT builds, first‑article inspection and yield ramp‑up.
• Define and execute mechanical test plans (drop, vibration, water ingress, UV, chemical resistance, abrasion) and maintain FMEA based on field data.
• Set up and manage a prototyping workshop equipped with 3D printers, CNC machines and hand tools.

Required profile

• Bachelor’s degree in Mechanical Engineering or equivalent (MSME preferred).
• 7+ years of experience in consumer electronics or wearable device development.
• Proven track record taking injection‑molded products from design through tooling to mass production.
• Hands‑on NPI experience with contract manufacturers, including pilot builds and first‑article inspection.

Required skills

• CAD (solid modeling) and GD&T.
• Injection molding design and tooling.
• Design for Manufacture (DFM) and tolerance analysis.
• IP67 waterproofing techniques.
• Jig and fixture design.
• Manufacturing process design and yield improvement.
• New Product Introduction (NPI) at contract manufacturers.
• FMEA and reliability testing (drop, vibration, water ingress, UV, chemical, abrasion).
• Prototyping tools: 3D printing, CNC machining.
