Shall we meet? 
You don't have to meet every single technical requirement. We are primarily curious about what you have built, what choices you have made, and where you want to grow. 
 
A CV or LinkedIn profile is enough to start the conversation. This will be followed by an introduction, a technical interview, and a practical case. 
 
At adesso, you don't just work on the technology of tomorrow. You also get the space to help determine how we build it.

Will you help build the next generation of software, where Java, AI, and autonomous agents converge?

At adesso Netherlands, we are developing ourselves into an AI First organization. We believe that AI is fundamentally changing the way we design, build, and use software. That is why we are looking for experienced Java Developers who look beyond traditional software development and get enthusiastic about AI-first and agentic software.

No isolated AI experiments or chatbots for the sake of chatbots. We build smart, scalable applications in which AI actually becomes part of the software and business processes.

And you can play an important role in that.

As a Senior Fullstack Java Developer, you will work on complex software solutions for organizations such as Rabobank, NS, Ahold, Alliander, EDSN, and bol.

You combine strong Java and fullstack knowledge with modern technologies and new possibilities surrounding AI. You develop robust backends, modern frontends, and smart integrations, but also look at how AI and autonomous agents can improve existing applications.

Think of applications in which AI agents independently perform tasks, combine information from different systems, and automate processes. Or integrating LLMs into existing Java applications, where security, reliability, and scalability are central.

You contribute to thinking about architecture and technical choices and get the space to research and actually apply new technologies.

• Developing scalable applications with Java, Spring Boot, Angular, and TypeScript.

• Building AI-first applications and integrating LLMs and AI agents into existing software systems.

• Developing APIs, microservices, and integrations that allow AI agents to collaborate securely with systems and data.

• Exploring and applying technologies such as Spring AI, LangChain4j, and agentic frameworks.

• Deploying AI within your own development process, for example for code analysis, testing, and documentation.

• Contributing to thinking about software architecture, security, cloud, and the step from AI prototype to production.

• Collaborating with experienced engineers and contributing to the development of our AI First Software Engineering proposition.

You are an experienced software engineer with a strong technical foundation. You follow new developments, dare to challenge existing ways of working, and enjoy developing new solutions together with colleagues.

You don't need to be an expert in Agentic AI yet. We are primarily looking for a strong engineer who understands how to build reliable software and is enthusiastic about giving AI an increasingly large role in it.
