Junior Software Engineer C++

Job Description

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.

How You Will Contribute And What You Will Learn

• 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.
  
  

Key Skills And Experience

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.
