Panel Wirer / Wireman

Where grids are constrained, we create capacity. Our intelligent battery storage technology delivers power and flexibility in on-grid and off-grid applications -  cheaper than alternatives, easier to deploy, with smart power control and grid-forming capabilities that enable seamless synchronisation with the grid and other power sources. Today we deploy these as off-grid solutions for construction, film & TV and to the energy utilities to replace diesel generators, or we put them behind the meter for C&I users and to solve grid constraints for EV charging. We empower businesses and communities with more power, lower bills, and electric freedom.

We are seeking a skilled Panel Wirer to join our production team, dedicated to the assembly and wiring of AC control panels for our MAX energy storage systems. This role is integral to ensuring our products are built to the highest standards of safety, performance, and quality.

As a Panel Wirer, you'll work in our manufacturing environment, transforming electrical schematics and engineering drawings into fully functional control panels that power our innovative battery storage solutions. Your craftsmanship and attention to detail will directly contribute to delivering reliable, safe, and compliant electrical systems for commercial and grid-scale applications.
