Mechanical Designer (Contract)

We are at the beginning of aglobal energy transformationof a scalenot seenin generations.A future low-cost, low-carbonelectricgrid, serving a world thatelectrifies everything,is within our reach.
The last remaining gap is breaking the link between electricity supplyand demand. Thelowest-cost, most sustainablesources ofenergytoday come from intermittent renewablegeneration;
But our homes, businesses and industries needelectricity at the flick of a switch.
That gap can be closed by energy storage: Devices that store electricity when it is plentiful, thenprovide powerback to the grid when it is needed.Solutions, includingones usinglithium-ion batteries,are being deployed in massive numberstostart filling thisgap. But so far,none of those solutionshave proventhe abilityto deliverpowerany time, anywhere, over decades of service: The level of reliabilitywe’vecome to expect, and that the future grid will need.
This is the biggest challenge in energy today. Invinity is at the forefront of finding a solution. And we need you to help us deliver it.
Developed,manufacturedand delivered by our teams in Canada and the UK,Invinity’svanadium flow batteries(or “VFBs”)can be installed anywhere andconsistently deliver electricityasneeded over a service life exceeding30years.Moreover,Invinity’sVFBs are highly recyclable,don’trely on rare or conflict minerals, andwon’tcatch fire.
Invinityis a globalVFBleader, with over 190 megawatt-hours of its batteriesoperational or inconstructionforover82 projects across 15 countries - more than any otheremergingenergy storage provider.We’vedeployed the largest flow battery systems in the U.S., Canada, Australia, and the UK. Along the waywe’veearned financial support fromthe UK Infrastructure Bank, the U.S. Department of Energy, and some of the world’s leading institutional investors.
Invinity is seeking an experienced Mechanical Designer to join its product development organization on the hardware design team.

Support the design of mechanical products, including system layout, packaging, and overall product configuration.
Create and maintain 3D CAD models, part and assembly drawings, bills of materials, and design documentation for components and subsystems.
Support prototype builds, review first articles, and incorporate feedback into design updates.
Assist with verification testing by preparing test hardware, documenting results, and updating designs as needed.
Provide technical documentation and design support for component sourcing and supplier coordination.
Maintain product lifecycle data, including drawings, bills of materials, specifications, and revision-controlled design records.
Qualifications
Diploma, degree, or equivalent training in mechanical design, mechanical engineering technology, or a related field.
Advanced proficiency in SolidWorks, Onshape, or a similar CAD system, including sheet metal design, electrical harness routing, and management of large assemblies.
Strong understanding of design for manufacturing, tolerance stack-up, GD&T, and practical mechanical design principles.
Ability to interpret and work from engineering calculations, test results, and design requirements to support detailed mechanical design.
5+ years of experience creating designs for fabricated components and assemblies using a range of manufacturing processes, including welding, forming, molding, and related techniques.
Safety-focused, with an understanding of applicable regulatory and product design requirements.
Nice to Have
Experience with DFMEA and fault tree analysis (FTA).
Experience designing fuel cells, flow batteries, or other electrochemical systems.
Experience supporting supplier coordination and contract manufacturing activities.
Experience with injection molding, rotomolding, and thermoforming.
