## About the Role

* A degree in Computer Science, Software Engineering, or a comparable qualification, or sound professional experience in professional software development
 * Strong programming skills in Golang (Go) (ideally in a cloud and microservices context) as well as practical experience in the Lua scripting language (e.g., for embedded / edge applications)
 * Solid understanding of cloud technologies (AWS, GCP, or Azure), containerization (Docker, Kubernetes), and CI/CD pipelines
 * Experience in developing IoT solutions or edge computing applications, preferably on Linux-based systems (e.g., Raspberry Pi, industrial PCs)
 * Confident handling of common network and IoT protocols (such as MQTT, REST) and ideally experience with industrial communication (Modbus)
 * A structured, solution-oriented mindset and the motivation to actively contribute to building Europe's largest decentralized Virtual Power Plant
 * Business-fluent German and English skills, both written and spoken

## Description

* Gateway Programming (Go & Lua): You write high-performance code for our edge controllers. With Golang, you build robust system services and communication layers; with Lua, you create lightweight, dynamically adaptable control scripts and protocol drivers for inverters, BESS, and HVAC systems
 * Cloud Services & Microservices: You design and program scalable microservices in Go within the cloud backend to process time-series data, telemetry, and manage fleet operations across hundreds of customer sites
 * Interfaces & Protocols: You implement communication protocols for the IoT ecosystem (MQTT, REST/gRPC) as well as for local equipment communication (Modbus TCP/RTU)
 * VPP & Trading Integration: You enable seamless data flow between local systems (meter readings, flexibilities) and our Virtual Power Plant for automated control based on spot market prices
 * Agile Collaboration: You work closely in a cross-functional team with system architects, PLC developers, and product management to swiftly bring new commercial energy management features to the platform
