Software Engineer - Optical Networks
Portugal
(Hybrid)
In an increasingly connected world, telecom networks are the backbone of global connectivity—and in the AI-driven data center era, optical networks are more critical than ever.
By joining the Optical Networks division, you’ll be part of an industry-leading team (recently boosted by the acquisition of Infinera) pushing the boundaries of fast, high-capacity network technology worldwide.
We operate in a high-trust, international, and collaborative environment where clean code, continuous learning, and engineering excellence are our North Star. We don't expect you to know everything on day one—we are looking for passionate problem-solvers who are excited to grow their careers alongside top industry experts.
Real-World Impact: You’ll contribute to real production code powering global connectivity from day one.
Mentorship & Autonomy: Work alongside senior architects in a culture that supports your learning curve, while giving you the space to take ownership of your ideas.
AI-Enhanced Workflow: Learn to use modern AI coding assistants and LLM utilities integrated directly into our Development Life Cycle (DLC) to automate boilerplate tasks, generate tests, and focus on high-level logic.
Your responsibilities
Architect & Code: Build high-performance applications for modern hardware architectures using Modern C++.
Modernize: Work with STL, Boost, and asynchronous programming to solve real-world system challenges.
Quality First: Learn and apply best practices in software robustness through comprehensive unit, E2E, and stress testing.
Collaborate & Learn: Participate in design discussions, code reviews, and cross-functional projects within a global, distributed team.
Your skills and experience
Core Essentials:
C++ Fundamentals: A solid grasp of Object-Oriented Programming (OOP), basic data structures, and memory management.
Growth Mindset: Strong curiosity for modern C++ standards, eagerness to learn, and a passion for technology.
Tooling Basics: Familiarity with Git, Linux environments, or scripting languages like Python (academic projects or internships count!).
Communication: Fluency in English and eagerness to collaborate across international teams.
Education: BSc or MSc in Computer Science, Electrical/Computer Engineering, or a related field (recently graduated or final-year students welcome).
Nice-to-Haves (Not mandatory – you’ll learn this with us!):
Exposure to embedded systems, multi-threading, or operating systems fundamentals.
Basic understanding of Optical Networks, Layer 0, or hardware components (e.g., ROADM, WSS, DWDM).
Experience with testing frameworks like GTest.
We offer:
A structured onboarding process to help you settle in and learn our tech stack.
A hybrid, flexible working environment in Portugal.
Exposure to cutting-edge AI and Optical Networking tech.
