We are at the beginning of a global energy transformation of a scale not seen in generations. A future low-cost, low-carbon electric grid, serving a world that electrifies everything, is within our reach.   The last remaining gap is breaking the link between electricity supply and demand. The lowest-cost, most sustainable sources of energy today come from intermittent renewable generation; but our homes, businesses and industries need electricity at the flick of a switch.  That gap can be closed by energy storage: Devices that store electricity when it is plentiful, then provide power back to the grid when it is needed. Solutions, including ones using lithium-ion batteries, are being deployed in massive numbers to start filling this gap. But so far, none of those solutions have proven the ability to deliver power any time, anywhere, over decades of service: The level of reliability we’ve come 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, manufactured and delivered by our teams in Canada and the UK, Invinity’s vanadium flow batteries (or “VFBs”) can be installed anywhere and consistently deliver electricity as needed over a service life exceeding 30 years. Moreover, Invinity’s VFBs are highly recyclable, don’t rely on rare or conflict minerals, and won’t catch fire.   Invinity is a global VFB leader, with over 190 megawatt-hours of its batteries operational or in construction  for over 82 projects across 15 countries - more than any other emerging energy storage provider. We’ve deployed the largest flow battery systems in the U.S., Canada, Australia, and the UK. Along the way we’ve earned financial support from the 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. In this role, you will support the development of mechanical products by creating and maintaining detailed designs, drawings, and documentation, and by collaborating with engineers and cross-functional teams to improve product quality, manufacturability, and consistency.  RESPONSIBILITIES - 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. Invinity Energy Systems is small enough that every team member plays a critical role in our daily business, but large enough to participate in landmark clean energy projects around the world. With its exposure to our most impactful emerging products, this role will be critical in us delivering on those opportunities. If you are great at what you do, willing to engage with our dedicated, collaborative culture, and motivated by taking on and delivering against some of the biggest opportunities in energy today, we’d love to hear from you.
