Python jobs in Germany

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 work across backend services that connect our mobile apps, web tools, and on-site hardware — designing secure, efficient, and reliable systems that keep chargers running smoothly, even offline.

This is not a “backend silo” role — you’ll collaborate across teams to shape architecture, streamline APIs, and automate processes end-to-end. From designing distributed systems on Google Cloud to optimizing data flow between devices and users, you’ll help ensure HeyCharge’s platform scales with our rapidly growing customer base.

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.

• Design, build, and maintain scalable, secure backend systems running on Google Cloud Platform.
• Develop and optimize APIs and data pipelines connecting chargers, mobile apps, and web dashboards.
• You’ll touch everything from user-facing frontend, billing and invoicing, reporting and analytics pipelines, to the magic that ****powers ****our underlying, patented SecureCharge technology.
• Collaborate with product, frontend, and hardware teams to deliver reliable, high-performance solutions.
• Implement best practices in security, testing, and observability across all backend services.
• Contribute to system architecture, code reviews, and continuous integration/deployment processes.
• Troubleshoot and resolve production issues, ensuring uptime and resilience.

• Strong experience in backend development using TypeScript.
• Experience with Python and/or Rust is a plus.
• Solid understanding of cloud-native architectures, ideally with Google Cloud Platform and especially Firebase.
• Experience with databases (SQL and NoSQL), event-driven systems, and microservice design.
• Knowledge of API security, encryption, and authentication patterns.
• Focus on automation, scalability, and maintainability.
• Excellent analytical and communication skills, with a hands-on, collaborative mindset.

• Experience with IoT, Bluetooth, or Zigbee ecosystems.
• Familiarity with EV charging, energy systems, or connected consumer products.
• Knowledge of real-time telemetry, fleet management, or device provisioning.

• Builder mindset: You create order, structure, and systems that make life easier.
• Ownership mentality: You take responsibility and see things through without being asked twice.
• Automation-first: You seek out ways to streamline repetitive tasks and free up time for higher-value work.
• Relationship builder: You inspire trust, build strong relationships, and represent HeyCharge with warmth and professionalism.
• Adaptable: You’re comfortable in a high-growth, ever-changing environment, and not afraid to jump into finance or ops tasks when needed.

• Work directly with the founding team of a Y Combinator-backed, award-winning startup building the future of EV charging.
• Shape strategy, processes, and decisions that have an immediate impact on company trajectory.
• Gain first-hand exposure to fundraising, product development, and international expansion.
• Be part of a small, ambitious team that values clarity, ownership, and clever solutions (and knows when to laugh at itself).
