Job summary

AgileEngine, LLC. is seeking a Senior Java Engineer to build and maintain Java and Spring Boot services for a high-stakes distributed payments platform. The role emphasizes production-ready delivery and strong ownership of microservices in a distributed, event-driven environment.

You will work on GraphQL APIs, integrate with SQS, Kafka, or RabbitMQ, and ensure transactional integrity with MySQL/Aurora. The team values in-depth observability, CI/CD discipline, and the use of modern tooling.

Qualifications

• 4+ years of backend engineering with Java and Spring Boot (Boot 3 preferred).
• Experience with GraphQL — either building APIs with Netflix DGS or consuming via Apollo GraphQL client.
• Hands-on experience with AWS SQS, Apache Kafka, or RabbitMQ in distributed systems.
• Strong JPA/Hibernate experience with MySQL/Aurora (Spring Data JPA).
• Writing JUnit 5 tests with Mockito and integration tests against live environments.
• Proficiency with Gradle multi-module builds.
• Experience with GitLab CI/CD pipelines and Datadog.
• Comfort using AI coding assistants to accelerate development while maintaining code quality.
• Experience with financial-grade backend systems requiring correctness and idempotency.
• Ability to reason about transactional boundaries across external systems.

Responsibilities

• 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 (Jacoco).
• Strengthen system reliability through observability, resilience patterns, and safe canary/production deploys gated by Datadog.

Job description

We are looking for a Senior Java Engineer to build and maintain Java and Spring Boot services for a high-stakes, distributed payments platform.

The mandatory requirements are 4+ years of backend engineering with Java and Spring Boot, Apollo GraphQL client and Aurora MySQL with JPA/Hibernate experience, event-driven systems, and experience with financial-grade systems.

WHAT YOU’LL GAIN

• Remote work — Work from where you feel most productive.
• Local presence in India — Work in a structured and compliant environment aligned with Indian regulations.
• Competitive compensation in INR — Receive compensation in INR, plus support for learning, education, and wellness.
• Exciting projects — Work with modern technologies for global clients and fast-growing companies.

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.
