Mechanical Engineer

Proxxi Technology Corporation builds wearable electrical hazard alerting devices that protect industrial workers. Our flagship product, Proxxi Voltage, is a wrist-worn device distributed worldwide to major utilities and industrial companies. When you ship work here, it ends up on the wrists of people doing some of the world's most dangerous jobs.

We're hiring a Mechanical Engineer to own all mechanical aspects of every Proxxi product, current and future. This is a hands‑on individual contributor role: you'll be our only full‑time ME, responsible for everything from enclosure detailing and DFM through injection mold tooling, assembly process design, and manufacturing engineering.

You won't be working in isolation. Our CTO (EE lead) and Head of Manufacturing both have hands in mechanical work and will be your closest collaborators. You'll also work with an external  to translate the industrial design concept into production‑ready mechanical designs. The ME function is yours to own, fully.

Expect to be in our Gastown office most days. The physical nature of the work (prototypes, builds, test rigs, CM coordination) rewards being there in person. This is not a role for someone who needs direction.

• Translate  into production‑ready CAD: parting lines, draft angles, wall thickness, rib and boss design, snap fits
• Tolerance stack‑up analysis across the full device assembly
• IP67 waterproofing systems (gaskets, O‑rings, adhesive bonding, ultrasonic welding)
• Integration of acoustic components, optical components, and user‑interface mechanisms (buttons, band attachment) into sealed enclosures
• Accessory and charger mechanical systems: alignment, retention, cable management
• Mechanical design for future products

• Mold tool drawings for all injection‑molded parts: gate location, ejector layout, cooling channels, cosmetic finishing specs
• DFM review, GD&T, assembly sequence definition, and error‑proofing
• Jig and fixture design for assembly, testing, and QC
• Manufacturing process design and yield improvement
• Mold maintenance and tool‑life management
• NPI support at our contract manufacturer: EVT and DVT builds, FAI, and yield ramp

• Define and execute the mechanical test plan: drop, vibration, IP67 water ingress, UV, chemical resistance, abrasion
• Mechanical quality standards and IQC/OQC criteria
• FMEA maintenance from field return data
• Prototyping workshop setup and ongoing management: 3D printers, CNC, hand tools, safe and well‑organized work spaces

• BSME or equivalent (MSME preferred but not required for strong candidates)
• 7+ years of mechanical engineering experience in consumer electronics or wearable device development
• You've taken injection‑molded products from design through tooling to mass production: not just designed parts, but owned the tooling process
• NPI (New Product Introduction) experience at contract manufacturers: pilot builds, first article inspection, process validation, and the transition to mass production
• Strong proficiency in Fusion 360 or Solid Works (we primarily use Fusion, but we'll work with you on the decision if you prefer Solid Works)
• Deep DFM skills: injection molding, assembly design, tolerance analysis, GD&T
• Hands‑on waterproofing experience for IP67 or IP68 products
• Comfort working with North American (Canada, US, Mexico) and Asia‑based contract manufacturers
• Self‑directed and curious. You spot what needs doing, dig into what you don’t yet know, and prefer making over meeting

• Wrist‑worn or watch‑form‑factor devices specifically
• Flex PCB integration within enclosures
• Injection mold tool design knowledge (not just DFM)
• FEA experience
• Acoustic component integration in sealed enclosures
• FMEA, SPC, and formal quality methodology
• Magnetic alignment or retention mechanism design
• Softgoods design (silicone, TPU, or textile watch bands)
• Overmolding and two‑shot molding (soft‑touch grips, sealed buttons, bumpers)
• Background in industrial or safety product development (PPE, hazard detection)
• Prototyping shop setup and management

• CA $110,000–$150,000, commensurate with experience
• Stock options in Proxxi Technology Corporation
• Fusion 360 and Solid Works licenses, 3D printer access, and prototyping tools provided
• Travel to contract manufacturers covered
• Hybrid schedule based in our Gastown office, with flexibility based on program phase
