Description In an increasingly connected world, the pandemic has highlighted just how essential telecom networks are to keeping society running. The Network Infrastructure group is at the heart of a revolution to connectivity, pushing the boundaries to deliver more and faster network capacity to people worldwide through our ambition, innovation, and technical expertise. Join Optical Networks division, where innovation meets scale in the AI-driven data center era. With the recent acquisition of Infinera, we have united two industry leaders to create an optical networking powerhouse—combining cutting-edge technology with proven leadership to redefine the future of connectivity. In Nokia, we are building the backbone of global connectivity. As a C++ Software Engineer, you will architect the future of Optical Networks technologies. We operate in a high-trust, international environment where clean code, decoupled architecture, and engineering excellence are our North Star. You will be an integral part of a cross-functional team, owning the full lifecycle from conceptual design to deployment. We empower our engineers to be proactive problem-solvers: If you identify a bottleneck or a potential system improvement, you have the autonomy to lead that change. We are committed to engineering efficiency. In this role, you will integrate AI-driven Development Life Cycle (DLC) tools into 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. Responsibilities Architect & Code: Build high-performance embedded applications for Intel and ARM architectures using Modern C++. Modernize: Utilize STL, Boost, and asynchronous programming to solve complex concurrency challenges. Quality First: Lead the charge on robustness by writing comprehensive unit, E2E, and stress tests. Collaborate: Engage in high-signal code reviews and contribute to team-wide design decisions in a global, distributed environment. Qualifications Professional Background: Master’s / Bachelor’s degree in Computer Science, Electrical Engineering, or a related field, and 5 years of relevant work experience. C++ Craftsmanship: Deep knowledge of OO concepts, inter-process communication, multi-threading, and data structures. Growth Mindset: A passion for exploring modern C++ standards and staying ahead of industry trends. Tooling Mastery: Familiarity with Git, Python, and GTest. Domain Expertise: Knowledge of DWDM, OTN, and embedded systems is highly valued. Specifically, experience or familiarity with optical components such as ROADM, WSS, DGE, and ILA is a significant advantage. Collaborative Excellence: Strong English communication skills and ability to collaborate effectively across different cultures and time zones. Professional experience in telecommunications (L0-L3 transport technologies). Fluency in German or willingness to learn. It would be nice if you also had: Professional experience in telecommunications (L0-L3 transport technologies). Fluency in German or willingness to learn.
