Backend Engineer – Access Routing & Trust; ART

What you are going to do

• Build, evolve, and operate a platform that processes millions of incoming requests and ensures they are securely and reliably routed to the right destinations
• Work on connecting applications across a complex landscape that spans cloud, private cloud, and existing systems, solving integration challenges along the way
• Design and implement routing and traffic management solutions that are both secure and highly performant under real‑world conditions
• Contribute to the transition from legacy systems to a modern, cloud‑native platform, helping make key architectural and operational decisions
• Help move the platform toward smarter, more automated operations by exploring AI‑supported workflows and enabling self‑service capabilities for internal teams
• Continuously improve reliability by strengthening observability, monitoring, and alerting so issues are detected and resolved before users are impacted
• Collaborate closely with application teams, architects, and other platform teams to integrate new services and reduce friction in how traffic flows through the organization
• Take ownership end‑to‑end: from design and implementation to deployment, operations, and incident response

• Salary between €4,527 and €6.036 based on 36 hours and depending on your knowledge and experience
• 13th month and holiday allowance are paid with your monthly salary
• 27 vacation days for a 5‑day working week and three Diversity Days
• A modern pension administered by Be Frank

• Travel allowance for using your own transport (you can declare the kilometres travelled)
• Allowances for setting up your home office and for internet use

You are a natural collaborator who enjoys working across team boundaries and understands that the best solutions emerge from strong alignment and shared ownership. You bring at least 3 years of hands‑on experience with Kubernetes and are comfortable deploying, operating, and troubleshooting containerised workloads in production environments. You have experience with CI/CD pipelines and strongly believe in automation as the foundation for reliable software delivery.

You have a solid understanding of networking fundamentals, and you are interested in how traffic flows through systems  enjoy working with open‑source tools and are not afraid to dive into their configuration and behaviour to make them work in a specific context. You care about observability and understand the importance of metrics, logs, and traces in running reliable platforms. You are comfortable working in complex environments where modern and legacy systems coexist, and you enjoy solving problems that don't have a straightforward answer.

You take initiative, explore unfamiliar territory when needed, and are motivated to continuously improve systems and reduce manual effort. You value well‑structured, secure, and maintainable configurations and code, and you gravitate toward modern engineering practices.

You will join a small, international team consisting of four engineers, a product owner, and an engineering manager. The team is intentionally small, which means every voice matters and your impact is immediately visible. At the same time, the scope is large: every request entering NN flows through what we build. We work closely together, challenge each other, and take pride in both our engineering craft and the platform we run.

Collaboration extends beyond the team as well — we actively engage with other teams and architects across the organisation to ensure our platform fits seamlessly into the bigger picture. If you enjoy working in a focused, high‑impact team where ownership, collaboration, and continuous improvement are key, you will feel right at home.
