Senior Full Stack Engineer

Project overview

Organizational Context

The COA (Central Agency for the Reception of Asylum Seekers) is responsible for the reception and guidance of asylum seekers in the Netherlands. Our services require reliable, transparent, and well-organized information provision. The ICT department plays a central role in this by structuring systems and processes to effectively contribute to our societal task.

Goal of the Assignment

The COA is an organization that constantly adapts to the political and societal reality. This requires IT that can switch gears quickly. This is only possible if we tackle it seriously: with reusable building blocks, with tests that prove a solution does what it should do, and with frameworks for privacy and information security that are integrated from the first line of code. This is exactly the work you will be doing at the COA. Technically, you will build on .NET, TypeScript, cloud native, and in containers.

You will ensure that the whole is testable and automatically rolls through the development pipeline, so that speed does not compromise quality. You will make choices that extend beyond this application. The contractor will realize transferable technical solutions and document the applied working methods, so that other development teams can apply them independently. Where necessary, the contractor will provide technical demonstrations and knowledge transfer, aimed at the reuse and independent application of the delivered building blocks.

This assignment contributes to sustainable and high-quality ICT support for the reception and guidance of asylum seekers.

Results

Team Context

The Opvang en Keten (TOK) Team is part of COA ICT. TOK develops and manages applications that are essential for the daily operations of the COA, from systems for employees at reception locations to information exchange with municipalities and chain partners. The assignment will be carried out largely independently and hybrid. Physical presence on location will occur when necessary for technical coordination, knowledge exchange, or collaboration with stakeholders, based on the content of the assignment.

Based on their expertise, the contractor can contribute to technical knowledge sharing sessions and working groups and advise on the application of development standards and architectural choices. Responsibility for the daily management of teams and employees falls outside the scope of this assignment.

Why this assignment?

What makes you a good fit for this assignment?

You are, first and foremost, a solid engineer. You write good software, you think about maintainability, and you know that a demo is different from something that runs in production. AI is a tool for you that makes you faster, not a replacement for your craftsmanship. You are curious about what comes up weekly, but sober enough to see what remains of it. Furthermore, you are entrepreneurial and patient at the same time. You don't wait for someone to give you an assignment: you see an opportunity, make it small enough to demonstrate, and seek out the people you need.

And if a team isn't ready for it yet, you take a step back instead of pushing harder. You enjoy making others better at something you already know how to do.

You possess:

Additional Information

• You will design and build the application in .NET and TypeScript, cloud native and in containers, from the initial concept to production and beyond.
• You will determine the architecture and monitor quality: only code that meets the standard will pass.
• You will set up the development pipeline with automated tests, reviews, and checks, so that speed does not compromise quality.
• You will document conventions and working agreements, so that what works here becomes the pattern for the next application.
• You will translate the frameworks for privacy and information security into guardrails and automated controls, together with our security and privacy colleagues.
• You will involve other development teams in this way of working: you will build along, explain, and transfer knowledge.
• You will explore new developments in the field, assess what has value for the COA, and justify why we do or do not adopt something.
• You start at the beginning. There is no legacy to work around; you will co-determine how we develop from now on.
• Your work impacts people. The systems you build are used by colleagues at reception locations and contribute to the reception of residents.
• The context is substantively challenging, which makes it interesting: sensitive data, strict frameworks, and an organization that is constantly in motion.
• You will establish a way of working that will be adopted by the entire ICT department thereafter.
• Minimum HBO (higher professional education) work and thinking level, with a relevant study background.
• Minimum 5 years of experience as a software engineer.
• Extensive experience with .NET and TypeScript, and with building applications that are actually in production.
• Experience with cloud-native development and containers.
• Experience with CI/CD and with automating the software development lifecycle (SDLC), from commit to delivery.
• Experience with AI-native development: working with coding agents like Claude Code, including critically reviewing generated code.
• Experience with setting up skills, conventions, and context for coding agents, and with evaluations that demonstrate that the result remains good.
• Experience with translating frameworks for privacy, information security, and responsible use of AI, including the AI regulation, into guardrails and automated controls.
• Transferability: you explain complex technology to colleagues who are not yet familiar with it, without simplifying it beyond recognition.
• Experience in a public or otherwise highly regulated environment is a plus.
• Experience in guiding or coaching development teams is a plus.
• A Certificate of Conduct (VOG) is required before the start of the assignment.
