Senior Mechatronic/
Mechanical Engineer

Transform the world as we catalyse the adoption of renewable energy.
The Job
EnergyBank is an early-stage start-up seeking high performing, pioneering and enthusiastic spirits to drive the rapid growth that we must achieve.

We are looking for a senior engineer to join us in the development of our deep-sea energy storage systems. You will be assisting with the successful conceptual development, prototyping, and testing of devices including a deep-sea mass handling system and an ultra-low-wear traction system. You will be based within our workshop spaces at Outset Ventures in Parnell, Auckland.

This role will include mentoring and guidance of less experienced engineers working on the project.

Building a thriving, diverse team is our priority, so even if you think you might not exactly meet our requirements, we would 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 four and eight kilometres. 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 for you to join us as well!
