MUST HAVES

• 4+ years of backend engineering with Java and Spring Boot (Boot 3 preferred) in production microservices.

• Demonstrated ownership of production services in a distributed systems environment.

• Experience with GraphQL — either building APIs with Netflix DGS or consuming them via the Apollo Java/Kotlin client ( Apollo GraphQL client experience required ).

• Hands-on experience with AWS SQS, Apache Kafka, or RabbitMQ in event-driven, distributed systems.

• Strong JPA/Hibernate experience with MySQL/Aurora (Spring Data JPA), including transactional design and optimistic locking.

• Experience writing JUnit 5 unit tests with Mockito and integration tests against live environments.

• Proficiency with Gradle multi-module builds .

• Experience with GitLab CI/CD pipelines and Datadog (metrics and monitors).

• Comfortable using AI coding assistants (e.g., GitHub Copilot, Claude) responsibly to accelerate development while maintaining code quality and correctness.

• Experience with financial-grade backend systems where correctness, idempotency, and consistency are non-negotiable.

• Ability to reason clearly about transactional boundaries across external systems (e.g., a third-party billing platform plus a local metadata store).

• Have built or maintained a production Spring Boot service that consumes events from SQS, Kafka, or RabbitMQ.

• Have designed idempotent event handlers for workflows.

• Have written JPA entities and managed schema migrations against a production MySQL/Aurora database.

• Have integrated with an external REST- or SDK-based third-party platform.

• Have set up or worked with Datadog monitors as deploy quality gates in a CI/CD pipeline.

• Upper-intermediate English level.

NICE TO HAVES

• Prior experience in the Billing or Payments domain.

• Experience with DynamoDB (AWS SDK v2) and/or MongoDB (Spring Data) in a multi-store architecture.

• Experience with Netflix DGS.

WHAT YOU WILL DO

• Develop and maintain backend Java/Spring Boot services across the Payments platform.

• Add new payment methods to the platform's existing capabilities.

• Contribute to feature development, bug fixes, and reliability improvements across these services.

• Deliver production-ready feature work and bug fixes through GitLab CI, with unit and integration test coverage that meets Jacoco gates.

• Strengthen system reliability through improved observability, resilience patterns, and safe canary and production deploys gated by Datadog monitors.
