MUST HAVES

• 4+ years of hands‑on backend engineering with Java and Spring Boot 3, building production microservices.
• Senior level with 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.
• Hands‑on experience with event‑driven, distributed systems using AWS SQS, Apache Kafka, or RabbitMQ.
• Strong JPA/Hibernate and Spring Data JPA experience with MySQL/Aurora, including transactional design and optimistic locking.
• Proficiency writing JUnit 5 unit tests with Mockito and integration tests against live environments.
• Experience with Gradle multi‑module builds.
• Experience with GitLab CI/CD pipelines.
• Experience with Datadog for metrics and monitors.
• Responsible use of AI coding assistants (e.g., GitHub Copilot, Claude) to accelerate development while maintaining code quality and correctness.

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

WHAT YOU WILL DO

• Develop and maintain backend Java/Spring Boot services, contributing feature development, bug fixes, and reliability improvements across billing and account management services.
• Solve problems involving transactional consistency, event-driven correctness, notification reliability at scale, and safe multi‑entity migrations for advertisers globally.
• Keep advertiser billing accounts accurate, compliant, and synchronized across multiple datastores (MySQL, DynamoDB, MongoDB) and external platforms (Zuora).
• Deliver production‑ready features and bug fixes through GitLab CI, ensuring unit and integration test coverage meets JaCoCo quality gates.
• Strengthen system reliability through improved observability, resilience patterns, and safe canary and production deployments gated by Datadog monitors.
