Work Model: Hybrid (Warsaw)
Work Authorization: Must already hold valid Polish work documentation (TRC, Karta Pobytu, or EU/Polish citizenship). Sponsorship is not available for this role.
About the Role
We are building a new engineering team for a global tier-1 financial institution to strengthen its deployment security platform. You will design and build backend microservices (Java 17+, Spring Boot) that secure internal software delivery pipelines—automating vulnerability detection, policy enforcement, and secrets management at enterprise scale. This is a long-term, multi-year program. You will work in a high-autonomy squad alongside SREs and DevOps engineers.
Key Responsibilities
- Design, develop, and optimize resilient microservices using Java 17+ and Spring Boot.
- Deploy and manage applications on Kubernetes (OpenShift) in AWS cloud environments.
- Build integrations with CI/CD pipelines (GitHub Actions) to enforce security gates.
- Own the full lifecycle: coding, testing, deployment, and production monitoring.
- Mentor 3–4 mid-level engineers and drive technical decisions within the squad.
Required Skills
- 8+ years of professional Java development (Java 11/17+).
- Deep expertise in Spring Boot, microservices, and RESTful API design.
- Hands-on experience with Kubernetes or OpenShift.
- Strong understanding of distributed systems (retries, circuit-breakers, observability).
- Excellent communication skills and comfort working in a large enterprise environment.
Nice to Have
- Experience with CI/CD tools (GitHub Actions, Jenkins, or GitLab CI).
- Familiarity with security protocols (OAuth2, OIDC, mTLS).
- Event-driven architecture (Kafka, RabbitMQ, or AWS SQS/SNS).
