Backend Engineer - Java and Kotlin (FinTech)

• Design, develop, and maintain backend services and APIs using Java and Kotlin. • Build and optimize services for performance, reliability, and scale. • Write clean, testable code and contribute to engineering best practices. • Develop and maintain data access layers and integrations with databases. • Implement and support microservices and/or service-oriented architectures. • Create and maintain automated tests (unit/integration) and participate in CI/CD. • Diagnose production issues, perform root-cause analysis, and help drive improvements. • Collaborate with frontend, mobile, DevOps/SRE, and QA to deliver end-to-end features. • Document system behavior, design decisions, and operational procedures. • Continuously improve observability (logging, metrics, tracing) and developer productivity.

• Experience with microservices, event-driven systems, or distributed systems. • Familiarity with messaging/streaming technologies (e.g., Kafka, RabbitMQ). • Experience with AWS/GCP/Azure services and cloud-native patterns. • Knowledge of observability tooling (e.g., Prometheus, Grafana, ELK, OpenTelemetry). • Experience with performance tuning, reliability engineering, and automated incident response. • Familiarity with security practices (authn/authz, OWASP principles, secrets management).
