- strong backend engineering track record building microservices in Java,
- solid understanding of event-driven architecture (Kafka, queues, topics), reactive patterns, at‑least‑once delivery, and idempotency,
- fluency in relational databases (ideally PostgreSQL), data modelling, SQL, migrations (preferably Flyway), and query optimization,
- hands-on experience deploying, running, and troubleshooting applications in Kubernetes (preferably EKS) and AWS tools (X-Ray, CloudWatch, OpenTelemetry),
- familiarity with GitOps and CI/CD (GitLab CI/CD, FluxCD),
- API Gateway experience — routing, policies, versioning, authentication, rate limiting
- Proven experience working in Scrum teams,
- growth mindset and willingness to adopt new technologies (e.g., GenAI-assisted coding),
- strong communication and collaboration skills.
- being a part of a fast-growing global fintech,
