introWe are looking for a talented Platform Engineer (Full Stack) to join our Internal Developer Platform (IDP) team at NN and help us achieve our goal of becoming a socially responsible tech company that delivers digital products our customers love.   

Wat ga je doen?

Wat je gaat doen

As a Platform Engineer within our IDP team, you will be responsible for enhancing the Engineering Experience for all engineers at NN. By delivering the Internal Developer Platform as a new product, you aim to enhance Flow State, reduce Cognitive Load and improve Feedback Loops for developers across the company.


Based on user research within NN’s developer community, we have identified a top three of challenges that engineers are facing within NN:

  • Knowing how to get stuff done in NN is hard
  • Our test environments make it impossible to have confidence in shipping software
  • Our road-to-production processes are unclear and ambiguous


The Internal Developer Platform team aims to resolve these challenges by delivering a more integrated and frictionless engineering experience. The following features are part of the platform:

  • Software Catalog: catalog of NN software and teams behind it
  • Paved Roads: batteries included scaffolding for a new service
  • Templates: productized building blocks you can use in your projects
  • DevOps Metrics: how well your DevOps team is performing
  • Tech Radar: tracking adoption and maturity of technologies
  • Tech Docs: publish and discover documentation
  • Architecture Decision Records: discover and publish architecture decision records
  • Day 2 Operations: dashboards for 2nd day operations


These features will be delivered through a GUI and GIT based interface using Backstage (open source) technology, hosted on Kubernetes and with integrations towards an extended package of back-end systems for orchestration mostly based on REST APIs and serverless.


To be successful, the team has identified six Internal Developer Platform design principles that will drive your engineering work daily:

  • The platform offers meaningful abstractions
  • The platform is thin
  • The platform centers around productized standards
  • The platform is secure and transparent
  • The platform supports self-service and is fully automated
  • The platform is composable and open


As a member of the team, you will navigate groundbreaking terrain. Leveraging technologies like serverless, Kubernetes, Typescript, Node.js, React, AWS and Backstage to deliver the Internal Developer Platform and optimize the NN engineering experience. Your responsibilities include:

  • Build & Run our Backstage based Internal Developer Portal:
    • TypeScript, Node.js, AWS, Kubernetes, PostgreSQL, OpenSearch
  • Understand and apply API-first approach (MACH architecture)
  • Understand and apply Domain Driven Design
  • Authentication / RBAC / OAuth2 / IAM
  • Work on CI/CD pipelines and automated tests
  • Write great documentation ( and Wiki)
  • Introduce InnerSource mechanisms to co-create selected platform features
  • Security mindset (SAST/DAST and Threat Modeling)

Je zal samenwerken met

Met wie je werkt

The Internal Developer Platform team is part of the Engineering Experience & Platforms domain. This domain is responsible for optimizing the NN engineering experience by delivering a frictionless and integrated engineering journey through the Internal Developer Platform and supporting the software delivery lifecycle with CI/CD solutions. While also offering several reliable platforms that provide integration or hosting solutions (e.g. API Gateway and Kubernetes). We serve DevOps teams within NN globally and we can measure our success using the DORA metrics (amongst others). We are successful when DevOps teams optimize their performance on deployment frequency, change lead time, change failure rate, mean time to recover. Aside of course from delivering a positive impact to developer happiness across the company.


The domain has a scale-up type of culture and consists of a group of energetic and empowered engineers and product teams. We strive to make Cloud-Native technology successful across the entire company (including our international units). We really value our culture and nourish it at every opportunity. Team events are regularly organized. Last year we did airsofting, go-karting, game days, had a Christmas event and did several dinners with the teams.


The IDP team has a strong product mindset. They work according to the double diamond model (design thinking) as they have a UX designer and User Researcher within the team that empathize with the end user and clearly identify problems to resolve. The skilled engineers within the team work closely together with them to develop and deliver features that help resolve these problems and deliver value to the end users. Via this way of working the outcome (value) is maximized and the team helps enhance the engineering experience for NN globally.
