Composites Engineer

Transform the world as we catalyse the adoption of renewable energy.
The Job
We are looking for an engineer or materials scientist to develop a composite deep-sea tethering system with unprecedented strength, fatigue and cost characteristics.

EnergyBank is an early-stage startup, seeking high performing, pioneering and enthusiastic spirits to drive the rapid growth that we must achieve.

This role will be based within our workshop spaces at Outset Ventures in Parnell, Auckland.

As we scale, building a thriving, diverse team is our priority, so even if you think you might not exactly meet our requirements, we'd still appreciate your application—we are hiring for many roles over the next few months.


EnergyBank was founded to capitalise on the opportunity of a lifetime while also accelerating society's decarbonisation. To do this, we are developing the next generation of energy storage technology.

Energy storage boosts the value of renewables by creating artificial demand during periods of renewable oversupply. Storage then displaces fossil-fuelled generation by supplying that energy back to the grid during renewable supply shortages.

Our technology works by moving multiple thousand-tonne masses back and forth between the ocean floor and its surface over vertical distances of between 4 and 8km. This process leverages the depth of the ocean and gravitational potential to store energy with radically improved economics.

To achieve our mission, EnergyBank has been joined by five venture capital funds that have supported success stories like Coinbase, Rocketlab and Canva. So if you are a collaborative high-performer with a passion for innovative problem solving, we would love you to join us as well!
