Mechanical Engineer
Proxxi
Job Description
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.
ABOUT THE ROLE
We're hiring a Mechanical Engineer to own all mechanical aspects of every Proxxi product, current and future. This is a handsâon individual contributor role: you'll be our only fullâtime 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 ID contractor to translate the industrial design concept into productionâready 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.
WHAT YOU'LL OWN
- Translate ID concept into productionâready CAD: parting lines, draft angles, wall thickness, rib and boss design, snap fits
- Tolerance stackâup analysis across the full device assembly
- IP67 waterproofing systems (gaskets, Oârings, adhesive bonding, ultrasonic welding)
- Integration of acoustic components, optical components, and userâinterface mechanisms (buttons, band attachment) into sealed enclosures
- Accessory and charger mechanical systems: alignment, retention, cable management
- Mechanical design for future products
Tooling & manufacturing
- Mold tool drawings for all injectionâmolded parts: gate location, ejector layout, cooling channels, cosmetic finishing specs
- DFM review, GD&T, assembly sequence definition, and errorâproofing
- Jig and fixture design for assembly, testing, and QC
- Manufacturing process design and yield improvement
- Mold maintenance and toolâlife management
- NPI support at our contract manufacturer: EVT and DVT builds, FAI, and yield ramp
Test, quality & workshop
- 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 wellâorganized workspaces
WHAT YOU BRING
- 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 injectionâmolded 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 SolidWorks (we primarily use Fusion, but we'll work with you on the decision if you prefer SolidWorks)
- Deep DFM skills: injection molding, assembly design, tolerance analysis, GD&T
- Handsâon waterproofing experience for IP67 or IP68 products
- Comfort working with North American (Canada, US, Mexico) and Asiaâbased contract manufacturers
- Selfâdirected and curious. You spot what needs doing, dig into what you donât yet know, and prefer making over meeting
BONUS POINTS
- Wristâworn or watchâformâfactor 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 twoâshot molding (softâtouch grips, sealed buttons, bumpers)
- Background in industrial or safety product development (PPE, hazard detection)
- Prototyping shop setup and management
WHAT WE OFFER
- CA$110,000â$150,000, commensurate with experience
- Stock options in Proxxi Technology Corporation
- Fusion 360 and SolidWorks 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
