Cloud & Backend Engineer (Python/Kubernetes/DevOps) - Hybrid Porto (3 days/week office)

ABOUT THE OPPORTUNITY

Join a delivery team assembled for a Belgian Telecommunications client, working on cloud infrastructure, backend services, and DevOps in a modern, technically ambitious environment. This is a role for a mid-to-senior engineer who is equally comfortable writing backend code and operating containerised workloads in production - someone with an ownership mindset from commit to deployment.

Language: English B2 minimum | Level: Mid-Senior | Location: Porto (hybrid, 3 days/week in office)

PROJECT & CONTEXT

You'll be part of a cross-functional team building and operating a cloud-native platform for a Telco client in Belgium. The work spans backend service development, Kubernetes-based container orchestration, CI/CD pipelines, networking and security, and observability tooling. The stack is broad and modern - and you won't be expected to know everything on day one. The team values engineers who learn fast, collaborate openly, and take pride in delivering reliable, high-quality systems.

Stack: Python, Node.js, TypeScript, JavaScript, Go, C, SQL, React - Kubernetes, Docker, LXC - GitLab CI/CD, Ansible, PyTest, Jest, Robot Framework - Prometheus, Grafana, Loki, Tempo - Nginx, Kong, Keycloak, IP networking, firewalling

WHAT WE'RE LOOKING FOR

• Up to 5 years of hands-on experience in software development and DevOps roles
• Strong command of at least one backend programming language - Python and/or Node.js preferred - with willingness to work across others as needed
• Practical experience building, deploying, and operating containerised workloads on Kubernetes in production environments
• Solid understanding of Linux environments and confident use of the command line
• Good grasp of networking fundamentals - TCP/IP, HTTP, DNS, firewalls, and reverse proxies
• Experience with CI/CD pipelines, preferably GitLab CI/CD, and a strong automation mindset
• Ability to troubleshoot production issues, drive defects to root cause, and deliver lasting resolutions
• Experience participating in code reviews and sharing knowledge constructively within a team
• Degree in Computer Science, Engineering, or a related field - or equivalent practical experience
• Proactive approach to continuous improvement of development processes, tooling, and automation
• English B2 or above - required for daily collaboration with Belgian client and cross-functional teams
• Available for hybrid work in Porto, 3 days/week

NICE TO HAVE

• Experience with observability tooling: Prometheus, Grafana, Loki, Tempo
• Familiarity with security and identity tooling: Keycloak, Kong, Nginx, Aikido
• Exposure to Go or C in backend or systems programming contexts
• Experience with Ansible for infrastructure automation
• Working knowledge of React for occasional frontend contributions
• Proficiency in French or Dutch - a meaningful advantage given the Belgian client context

Compensation: €1700- €2300/month net, depending on experience and seniority level.
