The Back-End Developer establishes the web development activities that are done at the back end of programs. The Back-End Developer covers server-side web application logic and integration and activities, like writing APIs, creating libraries, and working with system components instead of frontend development, which focuses on customer-facing services and programs. The Back-End Developer focuses on the design of effective and efficient solutions by analysing the website's performance demands and goals; development and administration of Application Programming Interfaces (APIs); develops data acceptance and storage solutions for websites; writes, tests, and maintains development solutions for code-related problems; identifies new features with developers, designers, and system administrators; creates a website architecture by utilizing correct product lifecycle approaches, such as Agile Scrum and frameworks; organizes the system logic; provides remedies to difficulties with the system; debugs and troubleshoots apps.
Introduction
Are you ready to play a key role in building solutions that accelerate and simplify our business processes or improve customer experience? Our GenAI Incubator team has one goal: create value by applying generative AI. We do this by quickly building prototypes and proof-of-concepts to demonstrate value and iterate from there on. In 2025 we focussed on small-scale experiments. In 2026 we will focus on high value and scalable solutions in production — and for that we need you.
What will you do?
As a Senior Backend Developer in our Business Development team, you will play a key role in driving digital solutions that help us create value for our customers and accelerate progress towards fossil freedom. Your expertise in building enterprise-grade production ready solutions with .NET and Azure will be central to developing and maintaining robust backend applications, enabling innovative customer solutions with lasting impact. Working alongside other backend and front-end developers, as well as business stakeholders, you will apply your experience to take a variety of applications into production, ranging from event-driven and messaging-based systems (e.g., Kafka) to cloud-native services on Azure, bringing a flexible, hands-on mindset and the versatility to contribute across different parts of the stack as needed.
Your daily responsibilities include:
•
• Designing, building and maintaining production-ready backend services using .NET on Azure
• Produce clean, maintainable code with strong tests, documentation, and sensible patterns
• Drive technical decision-making (trade-offs, performance, reliability, cost)
• Implementing event-driven architectures that support efficient communication between systems
• Collaborating closely with developers and stakeholders to deliver complete solutions, and own features end-to-end: discovery, design, implementation, testing, deployment, monitoring
You will contribute to architectural decisions by applying your technical insight and experience, always considering the needs of both the business unit and our customers. Success in this role means creating secure, high-performing systems that support new business opportunities while helping colleagues grow through open collaboration. By championing quality standards and sharing knowledge openly, you help shape an environment where every solution is stronger because it’s built together.
Who are you
You thrive in a collaborative environment, where sharing knowledge and learning from others comes naturally. With at least five years of experience as a backend developer, you bring deep expertise in .NET Core and C#, enabling you to design and maintain robust applications that drive business development forward. Your hands-on experience with Microsoft Azure, including Functions, Key Vaults, App Insights, Container Apps, Service Bus and Event Grid, means you are comfortable working with cloud technologies to deliver scalable solutions.
You have worked with event-driven architectures and are familiar with messaging systems such as Kafka or similar platforms. Experience with Infrastructure as Code (IaC), CI/CD pipelines and container technologies like Docker or Kubernetes is essential for ensuring high-quality deployments. You approach challenges thoughtfully, combining technical skill with an open mindset to explore new ideas.
We believe your strengths include:
•
• Communicating clearly and proactively across teams to deliver integrated solutions
• Championing best practices in code quality, security and performance by supporting your colleagues
• Engaging creatively with new technologies to find practical ways forward
• Working together closely with DevOps and frontend specialists to achieve common goals
• Sharing your expertise while remaining receptive to diverse perspectives
Education: Work experience in the energy sector is preferred but not mandatory.
Practical information:
•
• Office presence (Amsterdam) is needed on 1 or 2 days per week. This is often on Wednesday but can be discussed within the team.
• CV's can be submitted in Dutch and English.
• Dutch speaking is required for this position.
