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.
ABOUT THE ROLEWe'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 ID contractor 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.
WHAT YOU'LL OWNTranslate ID concept 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
Tooling & manufacturing
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
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 well-organized workspaces
WHAT YOU BRINGBSME 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 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
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
BONUS POINTSWrist-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
WHAT WE OFFERCA$120,000–$165,000, 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
