Jobbeschreibung

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.

About the Role

We are looking for a hands‑on backend engineer with a strong technical foundation and a passion for building systems that bridge hardware and software. You will architect, implement and optimise distributed systems that connect thousands of chargers and users globally.

This role sits at the intersection of backend development, systems architecture and product engineering – ideal for someone who enjoys solving complex real‑world problems with elegant and scalable solutions.

Work closely with hardware and mobile teams to integrate physical interactions into seamless digital experiences.

Build and maintain secure, efficient data pipelines that support real‑time operations.

Scalability, Security & Observability

Implement fault‑tolerant designs, monitoring tools and alerting systems.

Champion best practices in data privacy, encryption and authentication.

Continuously improve system performance and reliability through automation and CI/CD pipelines.

Collaboration & Technical Leadership

Partner with product and design teams to translate technical capabilities into customer value.

Lead by example through code reviews, documentation and mentorship.

Contribute to long‑term architectural strategy and roadmap.

Essential knowledge, skills & experience

5 years of experience in backend development with TypeScript / NestJS.

Strong understanding of Google Cloud Platform (GCP) – particularly Firebase.

Proven experience designing microservices, event‑driven architectures and distributed systems.

Solid background in SQL and NoSQL database design.

Experience with API security, encryption and authentication protocols.

Hands‑on approach able to move from architecture to implementation with speed and precision.

Excellent communication skills and ability to collaborate across technical and non‑technical teams.

Fluency in English (German is a plus).

Nice‑to‑have

Experience with IoT messaging protocols (MQTT, WebSockets, BLE).

Background in connected devices, mobility or energy systems.

Familiarity with Rust or Angular.

Passion for embedded systems and products that connect the digital and physical worlds.

Previous experience in EV charging, smart home or hardware‑integrated platforms.

Soft Skills

Ownership mindset – takes initiative and drives projects independently.

Clear communication – collaborates effectively across technical and product teams.
