Junior C++ Software Engineer

Location: Germany Department: Applied R&D

You will be an integral part of the software organization that develops the embedded software for large-scale optical telecommunication systems. To support the needs of our customers we operate complex ASICs and FPGAs, run software in an embedded computer network of multicore CPUs, provide board support packages and carrier-grade application code, and maintain a CI/CD pipeline.

We empower our engineers to be proactive problem-solvers: If you identify a bottleneck or a potential system improvement, you are encouraged to bring it forward and learn how to contribute to its resolution. In this role, you will utilize AI-driven Development Life Cycle (DLC) tools in your daily workflow. By leveraging advanced AI coding assistants and LLM-based utilities, we automate boilerplate tasks, accelerate unit test generation, and enhance code analysis. We want our engineers focused on high-level architecture and complex logic while utilizing the latest tooling to streamline execution.
