Your role in the team

  • Help build and further develop the platform backend: You develop scalable, maintainable microservices for br.AI.n and SemReasoner, using Java and Spring Boot as the technical foundation and keeping a clear focus on architectural quality.
  • Implement agentic integrations: You integrate external services and protocols into our platform—including MCP servers, LLM APIs, and third-party systems—thereby specifically expanding the capabilities of our agent architecture.
  • Understand and extend the semantic backend: You work closely with the SemReasoner core—ontologies, knowledge graphs, and semantic reasoning aren’t just buzzwords to you; they’re building blocks you turn into production-ready services.
  • Own CI/CD & deployments: You build and maintain robust deployment pipelines (GitLab CI, GitHub Actions, or similar) and ensure that new features are released to production quickly, securely, and reproducibly.
  • Operate cloud and container environments: You deploy our services to Kubernetes and cloud environments (AWS, Azure, or GCP), ensuring they’re not just up and running, but operationally robust.
  • Take on MLOps: You integrate AI workflows into our production infrastructure—from model deployment to automating training and inference pipelines (e.g., with Kubeflow, MLflow, or Argo Workflows).
  • Drive proof of concepts forward: You test new ideas early and pragmatically, with a clear validation goal—and know when a POC is production-ready and when it isn’t.

Our expectations of you

Qualifications

  • Understanding of agentic AI: You think AI-native—you understand how LLMs, agents, and semantic reasoning work together, and can apply this understanding to backend architecture decisions.
  • DevOps expertise: CI/CD isn’t an add-on for you—it’s standard practice. You build pipelines that make the team faster, not slower.
  • MLOps affinity (a plus): If you’ve already worked with Kubeflow, MLflow, or similar tools, that’s even better. If not, you bring the curiosity and willingness to learn to get up to speed quickly.
  • Analytical depth: You love delving into complex problems—and finding solutions that not only work but will still be easy to understand six months from now.
  • Team orientation & communication: You work openly, proactively share knowledge, and contribute constructively to architecture discussions—even when things get uncomfortable.

Experience

  • Strong backend engineering skills: Several years of experience with Java and Spring Boot, microservice architectures, and designing scalable, loosely coupled systems—you know what holds up in production and what doesn’t.
  • Cloud & Kubernetes: You have already operated services in cloud environments and know how to orchestrate container workloads effectively. A vendor preference is not required—but experience is.

What we offer

  • Stay healthy and fit: We support the health of our adessi with sports benefits such as discounted gym memberships, covering court rental costs for activities like badminton, padel tennis or football, and regular preventive health check-ups.
  • Find your work-life balance: Our time-off program and flexible working arrangements help you achieve the right balance between work and personal life.
  • Time for family: Our goal is to bring the two worlds—family life and work life—together. To achieve this, we support our adessi as much as possible with a wide range of offerings, such as holiday childcare, daycare partnerships, parent-child offices, and events where the whole family is welcome.
  • Learn and grow with us: With over 400 training opportunities and our digital learning platform, we support your continuous development.
  • Experience true team spirit: Shared events, Welcome Days, company runs, and our buddy system strengthen our sense of togetherness and make you feel part of the team from day one.
