Location: Portugal (Hybrid)
Division: Optical Networks (Nokia)
In an increasingly connected world powered by AI-driven data centers and global telecom infrastructure, optical networks are more critical than ever.
By joining our Optical Networks division—recently boosted by the acquisition of Infinera—you’ll be part of an industry-leading team pushing the boundaries of ultra-fast, high-capacity network technology worldwide.
Whether you are a passionate junior engineer / recent graduate looking to accelerate your career under expert mentorship, or a mid-level software engineer ready to take ownership of complex systems and influence architectural decisions, this role offers an ideal environment to grow and thrive.
We operate in a high-trust, international, and collaborative environment where clean code, continuous learning, and software craftsmanship are our North Star. We don’t expect you to know everything on day one—we are looking for curious problem-solvers who are excited to grow alongside top industry experts.
Why You’ll Love Working With Us
- Real-World Global Impact: Write high-performance code that directly powers mission-critical global connectivity from day one.
- Mentorship & Ownership: Enjoy structured guidance to navigate your learning curve as a junior, or technical autonomy to drive features and design choices as a mid-level engineer.
