The role
Will you help build the next generation of software, where Java, Kotlin, and Agentic AI converge?
At adesso Nederland, we are developing ourselves into an AI First organization. We believe that AI is fundamentally changing the way we design, build, and use software. Therefore, we are looking for experienced Java/Kotlin Developers who look beyond traditional backend development and get enthusiastic about AI-first and agentic software.
No isolated AI experiments or chatbots without a clear purpose. We build smart, scalable applications in which AI truly becomes part of business processes and existing IT systems.
And you can play an important role in that.
What you'll do
As a Senior Java/Kotlin Developer, you will work on complex software solutions for organizations such as Rabobank, NS, Ahold, Alliander, EDSN, and bol.
You develop robust backend applications, APIs, and integrations that support business-critical processes. At the same time, you research how AI and autonomous agents can make existing applications smarter.
Think of integrating LLMs into Java or Kotlin applications, developing agentic workflows, and building systems in which AI agents independently plan tasks, process information, and execute actions within clear frameworks.
You contribute to thinking about architecture, technical choices, security, and scalability. In doing so, you combine proven software engineering principles with the possibilities of new AI technology.
Designing and developing scalable backend applications with Java, Kotlin, and Spring Boot.
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 discussions on software architecture, cloud, security, and reliably bringing AI solutions into production.
Mentoring other developers and contributing to code reviews, knowledge sharing, and our AI First Software Engineering proposition.
Requirements
You are an experienced software engineer who looks beyond just code. You understand how complex systems work, think critically about technical choices, and enjoy discovering new technologies.
You don't need to be an Agentic AI expert 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 that.
Hiring process
Shall we meet?
You don't have to meet every 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.
About adesso Netherlands
In their own words
About the company & team
You will join a team of about 25 driven medior and senior developers. We are large enough to deliver serious projects and small enough to know one another. Everyone has influence, and good ideas are not just heard, but also tested.
We deploy our development expertise at renowned companies in the Netherlands. There, we build solutions that matter using Java and Kotlin, and we use AI to achieve the best possible results. We continuously investigate how AI can make our work and that of our clients smarter.
Development comes first. During our knowledge evenings, we share what we learn, and we visit international (inter)national conferences annually to stay sharp. Additionally, we meet regularly for informal activities, because good collaboration begins with truly knowing each other.
Why adesso? Because with us, you can truly help build.
At adesso Netherlands, it is about more than just technology. We build smart solutions that actually add value for our clients. No endless experiments or AI just because it's hip, but technology that works and makes an impact.
We are part of the international adesso Group, with over 11,500 colleagues in more than 60 locations. At the same time, we are a relatively small and personal team in the Netherlands, with short lines, a lot of freedom, and room for individual initiative.
Large enough to make an impact, small enough to feel the difference.
AI First: building the future together
At adesso Netherlands, we are developing into an AI First organization. We believe that AI fundamentally changes the way we develop software, work with data, and help clients.
That is why we look beyond isolated AI experiments. We build smart data platforms, AI-first applications, and agentic solutions that truly become part of business processes.
That also means we continue to innovate our own way of working. We embrace new technology, but remain critical: not everything needs AI. The best solution always comes first.
And perhaps most importantly: the people
We love colleagues who are curious, share knowledge, and help each other forward. People who are good at their craft, but also enjoy collaborating. With us, you get trust, responsibility, and the freedom to actually execute ideas.
