Job Summary

In this role, you will develop scalable microservices using Java and Spring Boot, integrate external systems, and manage CI/CD pipelines for automating AI workflows in cloud environments.

Job Technologies

Your role in the team

  • Contribute to building and further developing the platform backend: You will develop scalable, maintainable microservices for br.AI.n and SemReasoner - using Java & Spring Boot as the technical foundation with a clear focus on architectural quality.
  • Implementing Agentic Integrations: You integrate external services and protocols into our platform — including MCP servers, LLM APIs, and third-party systems — thereby purposefully expanding the capabilities of our agent architecture.
  • Understand & Extend Semantic Backend: You work closely with the SemReasoner core - ontologies, knowledge graphs, and semantic reasoning are not just buzzwords for you, but building blocks that you translate into production-ready services.
  • Responsible for CI/CD & Deployments: You build and maintain robust deployment pipelines (GitLab CI, GitHub Actions, etc.) and ensure that new features are deployed to production quickly, securely, and reproducibly.
  • Operate Cloud & Containers: You bring our services into Kubernetes and cloud environments (AWS, Azure, or GCP) — with the aim of not only making them operational but also ensuring they are robust and reliable.
  • Tackle 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).
  • Driving Proof-of-Concepts forward: You test new ideas early, pragmatically, and with clear validation goals — and you know when a POC is production-ready and when it is not.

Our expectations of you

Qualifications

  • Agentic AI understanding: You think AI-native — you understand how LLMs, agents, and semantic reasoning interact, and you can incorporate this understanding into backend architecture decisions.
  • DevOps competence: CI/CD is not an add-on for you, but standard. You build pipelines that make the team faster - not slower.
  • MLOps affinity (plus point): If you have already worked with Kubeflow, MLflow, or similar tools, even better — if not, you bring curiosity and willingness to learn to quickly get up to speed.
  • Analytical depth: You love to delve into complex problems - and find solutions that not only work but are also understandable six months later.
  • Team orientation & communication: You work openly, share knowledge proactively, and contribute constructively to architecture discussions — even when it becomes uncomfortable.

Experience

  • Solid backend craftsmanship: Several years of experience in Java and Spring Boot, microservice architectures, and designing scalable, loosely coupled systems - you know what works in production and what doesn't.
  • Cloud & Kubernetes: You have already operated services in cloud environments and know how to orchestrate container workloads cleanly. Vendor preference is not a must - experience is.
