GT Overview

GT was founded in 2019 by a former Apple, Nest, and Google executive. GT’s mission is to connect the world’s best talent with product careers offered by high-growth companies in the UK, USA, Canada, Germany, and the Netherlands.

On behalf of HeyCharge , GT is seeking a Senior Backend Engineer to take ownership of the core backend systems powering a globally scalable EV charging platform. You will help design and build the backbone that connects chargers, cloud, and user interfaces — ensuring HeyCharge products work seamlessly online and offline.

About HeyCharge

HeyCharge is a Munich-based startup on a mission to make electric vehicle (EV) charging more accessible, reliable, and affordable.

Their platform focuses on software and connectivity rather than hardware — simplifying the entire lifecycle of charger management, from installation and billing to monitoring and load control.

In Germany, HeyCharge operates as a full-service Charge Point Operator (CPO), while their patented SecureCharge technology powers a global platform used by other CPOs and manufacturers to build offline-capable, secure, and cost-efficient charging solutions.
Backed by Y Combinator and expanding rapidly across Europe, HeyCharge is redefining how EV charging infrastructure is deployed and managed.
