Join us as a Full Stack Developer and build our Data Portal and ecosystem: the central platform where our data and AI experts manage and provision projects, data products and workspaces. You work with Python, Next.js, typescript, AWS and Databricks to create clear, compliant, reliable and user-friendly solutions that help others do their work better.
Uitdagingen
In this role, you will design and develop the Data Portal: our central web application that connects all data and AI platforms and services, forming a core part of PostNL’s data ecosystem. You’ll focus primarily on the backend, building scalable database structures, secure APIs, and integrating systems such as AWS services, Databricks workflows, and identity management. You’ll manage database migrations using Alembic and ensure processes around projects, users, and data access run smoothly.
In addition, you’ll work on the frontend with Next.js, building clear and simple interfaces. We already have a design system in place, so this is not about pixel-perfect UI work — the focus remains on backend functionality and integrations. You’ll integrate systems such as Ontos, handle lifecycle notifications, and support automations for our data professionals.
Je verantwoordelijkheden
Visible work: The Data Portal is the starting point for hundreds of data and AI professionals. You make their work smoother by building and improving features in Python and Next.js, and by connecting platforms such as Databricks and Ontos. Every change you make helps our colleagues work with data faster and more easily.
Challenge: You work with a modern and varied tech stack. On the backend you use Python, SQLAlchemy and Alembic to design and migrate databases. You build and connect REST APIs with AWS services such as Lambda, Step Functions and SDKs. You integrate with Databricks (Unity Catalog, APIs, workspaces) and Ontos as our data product catalog. Your challenge is to keep all these parts working together in a stable and scalable way.
Good atmosphere: You’ll be working with co-workers who are eager to seize opportunities and help each other move forward.
Flexibility: You'll work from home and at a flex spot in our bustling, state-of-the-art office in the historic Stationspostgebouw (next to Holland Spoor station).
Responsibility: You’ll have a big say in your work and working hours.
Development opportunities: You’ll have plenty of opportunities to take courses and grow into other positions or departments.
Wat breng jij mee?
You work meticulously, think logically, and enjoy making complex systems clear and scalable. You switch easily between different tech stacks and teams. You can translate architectural requirements and the needs of architects and the Platform Owner into clear, maintainable solutions. You place a high value on technical quality: you write testable code, design robust APIs, and build systems that other colleagues can confidently build upon. You combine strong full-stack skills with a platform mindset and take pride in clean database design and scalable systems.
You Also Recognize Yourself In The Following
An innovative position and work that affects literally every street in the country.
