About RMT Labs

RMT Labs SA is a Luxembourg-based research and technology company building the future of hiring in Europe. We operate two complementary brands: Talent Quanta, a profitable recruitment and ICT-consulting business serving clients across Europe since 2022, and Skillbourg, an AI-powered talent platform born from that real-world recruitment intelligence.

About the role

As a Java Developer in our consulting engineering team, you will build and maintain backend services for international clients, working in our distributed Luxembourg and Bucharest team. You will work on real production systems in regulated environments, where reliability, security and clean code matter. You will be part of a delivery team with senior developers, QA and a project lead, and you will work directly with client stakeholders.

What you will do

• Build and maintain Java services and REST APIs with Spring Boot

• Develop microservices that integrate with client systems, databases and message queues

• Write clean, well-tested code and take part in code reviews

• Investigate production issues and improve the performance and stability of existing services

• Work in agile sprints with colleagues in Luxembourg and Bucharest and with client teams

• Document your work so client teams can run and maintain it

What you bring

• 3+ years of professional experience with Java (Java 17 or newer)

• Hands-on experience with Spring Boot, REST APIs and microservices

• Good knowledge of SQL and relational databases such as PostgreSQL or Oracle

• Experience with Git, CI/CD pipelines and automated testing (JUnit, Mockito)

• Working knowledge of Docker; Kubernetes is a plus

• You work well remotely: you communicate clearly, plan your own work and ask when something is unclear

Nice to have

• Experience with Kafka or other messaging systems

• Previous projects for EU institutions, banks or other regulated sectors

• Curiosity about AI and LLM-based tools in software development
