The Vision 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. The Role & Innovation 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. The AI-Enhanced Workflow: 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. 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. You have : C++ Craftsmanship: Deep knowledge of OO concepts, 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 . Communication: Fluency in English and the ability to collaborate effectively across different cultures and time zones. It would be nice if you also had: Domain Expertise: Knowledge of Layer 0 (DWDM) and embedded systems is highly valued. Specifically, experience or familiarity with optical components such as ROADM, WSS, DGE , and ILA is a significant advantage.
