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 Full-Stack Engineer to help build and evolve the systems powering a globally scalable EV charging platform. You’ll work on applications that connect chargers, cloud, and users — 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’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.
