Senior Backend Engineer
Summary
We’re looking for a Senior Backend Engineer to join HeyCharge and help build the systems powering our globally scalable EV charging platform. You’ll architect and build the systems that bridge digital and physical worlds — connecting chargers, cloud, and user interfaces into one seamless platform. From low-level communication protocols to the APIs that power mobile and web experiences, you’ll help define how HeyCharge operates at global scale — online or offline. This role sits at the intersection of backend, systems, and product architecture — ideal for engineers who love building elegant, scalable systems that power real-world devices, not just web apps.
About HeyCharge
HeyCharge is a Munich-based startup on a mission to make EV charging more accessible, reliable, and affordable. While hardware is required for EV charging, it’s incidental to our core offering: our powerful platform simplifies the entire lifecycle of EV charger management. From installation and billing to monitoring and load management, HeyCharge enables property operators to offer EV charging as an amenity without the complexity. As a full-service Charge Point Operator (CPO) in Germany, we work with leading property owners and asset managers to deliver turnkey charging solutions. At the same time, our patented SecureCharge technology powers a global platform, allowing other CPOs and OEMs to build their own services with offline-capable, cost-effective, and secure charging infrastructure. With backing from leading investors (including Y Combinator) and a growing international footprint, HeyCharge is scaling rapidly across Europe and beyond.
Responsibilities
- Architect and implement core backend systems for a distributed, real-world platform connecting thousands of real estate sites, chargers, and users.
- Design data and messaging flows between chargers, apps, and cloud services with resilience and efficiency at the forefront.
- Drive architectural decisions for APIs, databases, and event pipelines that scale globally.
- Champion best practices in security, observability, and fault-tolerant design — balancing pragmatism with rigor.
- Collaborate with hardware, mobile, and product teams to translate physical interactions into digital experiences.
- Lead by example in code reviews, CI/CD, and automation — helping the team move fast without breaking reliability.
Qualifications
- Strong background in TypeScript/NestJS/Node.js.
- Experience with Google Cloud Platform (GCP) and especially Firebase.
- Experience with databases (SQL and NoSQL), event-driven systems, and microservice design.
- Demonstrated track record of designing and delivering complex systems.
- Knowledge of API security, encryption, and authentication patterns.
- Focus on automation, scalability, and maintainability.
- Proven ability to move from architecture to implementation — not just drawing boxes, but making them real.
Bonus Points (or, “What Makes You a Great Fit”)
Experiences with:
- Understanding of IoT messaging protocols (MQTT, WebSockets, BLE, etc.) and secure device onboarding.
- You’ve built or scaled systems that connect the physical and digital worlds (IoT, smart home, energy, mobility, etc.). In particular Zigbee and/or Bluetooth-based products.
- You thrive in early-stage environments where architecture, automation, and shipping coexist.
- Development with Rust, front end in Angular
- Familiarity with EV charging, energy systems, or connected consumer products.
- Deep curiosity about connected products, embedded systems,...
HeyCharge offers offline-first Bluetooth EV charging technology enabling secure authentication and billing without internet, providing reliable and cost-effective EV charging solutions primarily for apartment residents and commercial sites.
