Senior Full Stack Developer

In a world where digital technologies are advancing at a rapid pace, changing the way we communicate and altering consumer behavior, we are looking for Developers passionate about software development and continuous learning and sharing. You will work in a cross-functional agile DevOps team with fellow Developers to solve complex technical problems and enhance our customers' online experience.

Job Description
This vacancy is to join a product development team dedicated to Customer Recognition, Identity & Access Management, and Solution-based account management.
You will work closely with product owners, designers, and back-end developers to build and optimize secure and intuitive login flows, improve trust-level-based authentication, and support multi-user account scenarios for solutions like EV charging, solar panels, and home energy management.

Your work will directly contribute to:

• Expanding authentication methods (e.g., SMS, passkey, PIN code).
• Implementing and optimizing Trust Levels and session management.
• Running A/B tests to improve IAM flows and UX.
• Ensuring compliance with accessibility standards for all users.

Your main responsibilities are:

• Develop high-quality, accessible, and responsive front-end experiences in Angular for our App and web touchpoints.
• Integrate front-end features with SAP, WSO2, and .NET back-end services.
• Contribute to secure and user-friendly authentication and authorization flows.
• Collaborate with UX, security, and product teams to refine customer journeys.
• Participate in A/B-testing experiments to validate UX and security enhancements.
• Ensure cross-platform consistency and accessibility compliance (including European Accessibility Act requirements).

Some Developers in the team focus more on front-end, some more on the back-end. In this role you would focus more on the front-end, but you are not afraid to touch the back-end!

We are only considering applications from people already living and working near Amsterdam!

Are you looking for complex coding challenges allowing you to contribute to our purpose? And do you enjoy switching between front-and back-end technologies? Are you naturally staying updated with the latest technology, just as we do?

Apply today if you meet the following requirements:

• You have a Bachelor or University degree and experience in back end development
• You are fully skilled in Angular (version 19+) and have experience or interest in:
• Modern front-end development with Angular, including component-based architecture and reactive programming;
• NX/Nrwl and mono-repo architectures for scalable application management;
• TailwindCSS, Signals, NGXS, Cypress, Jest and other related tools
• Capacitor hybrid development for mobile development

You also have working knowledge of or exposure to:

• .NET 8 for API integration and back-end support;
• Microsoft Azure services such as Web Apps, API Management, App Configuration, Container Apps, and Cosmos DB — especially where they intersect with front-end concerns (e.g., authentication, environment configuration, and API consumption).

On top of that our tech stack contains:

• Yaml pipelines; Azure DevOps repo; Capacitor
• ASP.NET (Core); Microservice architecture
• SAP as a back-end, with several other db's
