Test 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.

As a Battery Test Engineer in Unit Cell R&D, reporting to the Manager, Unit Cell R&D in the Technology Team, you will work with an international, collaborative team to research, develop and verify new unit cell technologies. You are familiar with testing requirements from flow batteries or other relevant electrochemical devices such as PEM fuel cells or electrolyzers. You have a solid understanding of engineering and DOE principles, data analysis, and accelerated lifetime test methodologies and can effectively present your work with strong communication and interpersonal skills. You enjoy hands‑on work and apply strong structured problem‑solving and troubleshooting skills.

Purpose of the Role

• Support the testing team in all aspects of the process, from mechanical to electrical, and concept through execution. Your goal will be to ensure the quality, accuracy, and repeatability of test data to help drive data‑based decisions.
• Support the testing team in design, fabrication, calibration, and commissioning of test equipment to ensure it is safe and fit for purpose.
• Procure all necessary tools and materials required for fabrication, assembly, and testing processes.
• Execute assigned tests, ensuring all procedures and safety practices are followed while delivering quality data to the internal customers in a timely manner.
• Maintain and make available proper documentation of test equipment, results, and data in the correct locations.
• Troubleshoot any issues that arise with test equipment and perform preventive maintenance tasks. This includes identifying and resolving equipment malfunctions, calibrating instruments, and ensuring proper function of the testing apparatus.
• Contribute to the development of new test equipment and collaborate with the engineering team to provide input, suggest improvements, and help validate the effectiveness of new testing systems.
• Share your ideas, suggestions, and efforts to enhance efficiency, optimize processes, reduce waste.

Required Skills and Qualifications

• 3+ years experience working hands‑on in product / R&D laboratory or test facility (flow battery or fuel cell test experience a plus).
• Understanding of instrumentation, control automation, and data acquisition systems.
• Hands‑on experience in test station design and modification or similar.
• You develop good relationships with team members and managers.
• Applied knowledge and basic problem‑solving techniques to define and resolve problems.
• Bachelor’s degree in Mechanical Engineering, Mechatronics or similar subject.
• Electrical engineering knowledge and hands‑on skills (e.g. test station wiring) an asset.
