Manufacturing Engineer

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.

This role will be within our Manufacturing Engineering team, reporting to the Production Engineering Manager. You will support the day‑to‑day manufacturing and mechanical/electrical assembly of our innovative energy storage machines across multiple concurrent projects and provide the communications link to and from the Engineering team and the Operations team, so that products can be manufactured in practice from the designs provided.
