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’re looking for a full-stack engineer with strong Angular expertise and solid backend experience.

While you’ll work across the stack, your main focus will be the frontend layer, developing feature-rich Angular applications that include not only UI but also significant business logic, data flow, and real-time interactions.

This role is ideal for someone who enjoys working on technically challenging frontends that integrate closely with APIs and cloud services.

Key Responsibilities

• Develop and maintain complex Angular applications with robust business logic and real-time data flows.
• Contribute to backend development and API integration using Node.js and GCP/Firebase.
• Ensure scalability, performance, and security of applications across the stack.
• Collaborate closely with product, design, and engineering teams to deliver reliable, high-quality features.
• Write clean, testable, and maintainable code following best practices.

Essential knowledge, skills & experience:

• 5+ years of experience in full-stack or frontend-focused development.
• Expertise in Angular and TypeScript (components, services, RxJS, state management).
• Experience with Node.js for backend development and API integration.
• Familiarity with Google Cloud Platform (GCP) and/or Firebase.
• Strong understanding of web application architecture, data flow, and performance optimization.
• Experience working with SQL/NoSQL databases.
• Solid grasp of security principles and authentication mechanisms.
• Fluent English (German is a plus).

Nice-to-have

• Experience with IoT protocols (MQTT, WebSockets, BLE).
• Background in connected devices, mobility, or energy systems.
• Familiarity with Rust or other backend languages.
• Experience with offline-first applications or PWAs.
• Passion for building products that connect hardware and software seamlessly.

Personal Characteristics

• 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 whatever task is needed.

Impact

• Your work will directly shape how millions of EV drivers interact with charging infrastructure.
• You’ll influence the system design of one of the most secure, offline-capable platforms in the energy transition.
• You’ll help define the future of connected energy systems — not maintain what already exists.
