We are hiring a Backend Engineer to join our payments platform team. You will design and build scalable REST APIs using Java Spring Boot and Python FastAPI services that process millions of transactions per day. You will own end-to-end feature delivery from API design through database schema design and production rollout.
- Design and implement RESTful APIs and microservices in Java Spring Boot following clean architecture principles
- Design PostgreSQL schemas, write optimized queries, create and maintain Alembic database migrations
- Implement authentication, OAuth 2.0 / JWT token flows, request validation, and structured error handling
- Integrate with Kafka for async event-driven processing of transaction events and webhook deliveries
- Optimize query performance through indexing, connection pooling, and Redis caching strategies
- Write comprehensive unit tests with JUnit and integration tests against ephemeral PostgreSQL instances
- Perform code reviews, mentor junior engineers, and contribute to engineering standards documentation
- Instrument services with structured logging, Prometheus metrics, and OpenTelemetry distributed tracing
- 4+ years of backend engineering experience in Java Spring Boot or Python FastAPI
- Strong knowledge of PostgreSQL, SQL query optimization, and relational data modeling
- Experience with Kafka, Redis, REST API design, and microservices architecture
- Hands-on Docker containerization and Kubernetes deployment
- Familiar with CI/CD pipelines (GitHub Actions or Jenkins)
