Vacatures engineer Rotterdam

Every secure login is a moment of trust. As a Senior Fullstack DevOps Engineer in our Customer Identity and Access Management (CIAM) B2B team, you'll shape the authentication experiences that welcome thousands of business customers and advisors into NN's digital ecosystem every day. Your work directly impacts how users authenticate, feel safe, and move effortlessly through their online journey. Backed by modern technology and a team deeply committed to delivering top-tier authentication flows, you'll sharpen your craft across the full stack — while contributing to one of NN's most essential digital touchpoints.

• Build and improve end-to-end authentication journeys for NN's business customers and advisors
• Translate UX and security requirements into clean, accessible, and high-quality frontend and backend implementations
• Design, develop, and maintain robust CIAM services that scale with our growing B2B landscape
• Own your work end-to-end: from idea and code to deployment and monitoring, fully automated through modern CI/CD practices
• Collaborate closely with fellow engineers, sharing knowledge and exchanging feedback through code reviews and pairing sessions
• Proactively seek collaboration beyond your team — with security, architecture, product, and other engineering teams — to ensure our authentication experiences fit seamlessly into the broader NN ecosystem
• Contribute to a healthy engineering culture where quality, security, and maintainability are non-negotiable

• You ship beautiful frontends in a modern framework like React or Vue.js and create rock-solid backends in a mainstream tech stack. JavaScript/TypeScript runs through your veins, and that's exactly what we need

• You understand CI/CD inside out and can set up pipelines that deploy applications safely and repeatedly to the cloud
