Profile match
Nokia is a Finnish telecommunications equipment company founded in 1865 as a paper mill, which became the world's largest mobile phone maker in the 1990s before selling that business to Microsoft in 2014. It now supplies network infrastructure to operators and enterprises, covering radio access equipment for mobile networks, optical and IP routing for transport networks, fixed broadband access, and a technologies division that licenses its cellular patent portfolio. Headquartered in Espoo and listed in Helsinki and New York, it runs Nokia Bell Labs as its research arm and has been expanding into data centre networking as operator spending has slowed.

We are looking for an experienced and highly skilled software engineer who thrives on solving complex technical challenges, designing scalable architectures, and delivering carrier-grade software solutions. In this role, you will take ownership of critical software components, drive technical decisions, and contribute to the evolution of high-performance networking platforms that operate at global scale.

You will collaborate with international teams of experts, influence product architecture, mentor engineers, and play a key role in shaping the future of optical networking technologies. This is an opportunity to combine deep technical expertise with technical leadership while contributing to some of the industry's most advanced networking solutions.

  • Drive software architecture and technical design decisions for networking and systems applications.
  • Develop scalable, resilient, and maintainable software solutions that meet demanding performance, availability, and reliability requirements.
  • Lead the resolution of complex technical challenges related to multi-threaded, distributed, and real-time systems.
  • Review architecture, design, and code to ensure alignment with engineering best practices, quality standards, and long-term maintainability.
  • Collaborate closely with Systems Engineering, Product Management, Hardware Engineering, and global R&D teams to define and deliver innovative solutions.
  • Troubleshoot and resolve critical software issues across multiple layers of the platform.
  • Drive adoption of modern software development methodologies, CI/CD practices, automation, and observability tools.
  • Mentor and coach junior and mid-level engineers, fostering technical excellence and knowledge sharing.
  • Contribute to strategic technology roadmaps and influence future product and platform evolution.
  • Lead technical initiatives and cross-functional projects from concept through delivery.
  • Act as a technical expert and trusted advisor within the organization.

Required:

  • 8+ years of professional software development experience with C++ in complex commercial, embedded, distributed, or networking environments.
  • Strong expertise in Modern C++ (C++11/14/17/20), including advanced language features, STL, design patterns, and performance optimization.
  • Deep understanding of object-oriented design, software architecture, data structures, algorithms, and design principles.
  • Strong experience with Linux-based development environments and software lifecycle management.
  • Proven experience designing and developing multi-threaded, concurrent, and distributed systems.
  • Experience leading software architecture discussions and making critical technical decisions.
  • Excellent debugging, troubleshooting, and performance analysis skills.
  • Experience with Git and modern software engineering practices, including code reviews and automated testing.
  • Strong communication and stakeholder management skills with the ability to collaborate effectively across global teams.
  • BSc or MSc in Computer Science, Telecommunications, Electrical Engineering, Software Engineering, or a related discipline.

Preferred:

  • Proven experience designing software architectures for distributed, real-time, or high-availability systems.
  • Strong understanding of CI/CD pipelines, automated testing frameworks, and software quality engineering practices.
  • Experience in telecommunications, networking, or optical transport technologies.
  • Knowledge of Optical Networks, DWDM, Layer 0/1 technologies, ROADM, WSS, coherent optics, or related domains.
  • Experience with system performance optimization, profiling, and scalability improvements.
  • Proficiency in Python, Bash, or similar scripting languages for automation and tooling.
