About the Role

We are looking for a highly skilled Senior Java Backend Developer with strong expertise in building scalable microservices and APIs. The ideal candidate will have hands-on experience with Spring Boot or Quarkus and API management using IBM API Connect (APIC). Experience in the Open Banking domain will be considered a strong advantage.

Key Responsibilities

  • Design, develop, and maintain scalable microservices using Spring Boot and/ Quarkus
  • Build, publish, and manage APIs using IBM API Connect (APIC)
  • Ensure high performance, security, and scalability of backend systems and APIs
  • Collaborate with cross-functional teams including product, QA, and DevOps
  • Troubleshoot, debug, and resolve production issues efficiently
  • Follow best practices for clean code, testing, and system design
  • Containerize applications using Docker and deploy on Kubernetes/OpenShift
  • Implement authentication/authorization using OAuth2/JWT standards
  • Write unit, integration, and contract tests
  • Collaborate with DevOps on CI/CD pipelines
  • Participate in code reviews, design discussions, Agile ceremonies
  • Monitor, troubleshoot, and optimize microservices performance in production

Requirements

  • 5+ years of experience in Java backend development
  • Strong hands-on experience with Spring Boot and Quarkus
  • Solid understanding of microservices architecture
  • Familiarity with API security and performance optimization
  • Java 11+ specifically (not just "Java backend development")
  • OpenShift alongside Kubernetes (currently only Docker/K8s is nice-to-have — should move to required)
  • Proficiency with Git and CI/CD tools (Jenkins, GitLab CI)
  • Working knowledge of SQL/NoSQL databases

Nice to Have

  • Experience in Open Banking or financial services domain
  • Knowledge of OAuth2, JWT authentication
  • Hands-on experience with Docker, Kubernetes, and cloud platforms (AWS, Azure, or GCP)
  • Apache Kafka or other messaging/event-streaming platforms
  • Observability tools — Prometheus, Grafana, ELK

  • Opportunity to work on scalable, enterprise-level systems
  • Collaborative and growth-focused environment
  • Exposure to modern technologies and architecture

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
