Develop automated tests using JUnit, Mockito, Cucumber, Selenium, JMeter, Gatling, WireMock, or comparable tools.

Build dashboards and operational alerts using Splunk, Kibana, AppDynamics, Instana, or Datadog.

Troubleshoot production issues by analyzing application logs, performance metrics, event flows, and database behavior.

Collaborate with product owners, architects, QA, database, security, and DevOps teams.

Drive application resiliency, performance improvement, cloud adoption, and engineering automation.

Required Skills

Advanced Java and J2EE development experience.

Strong experience with Spring Boot, Spring MVC, Spring Data, Spring Batch, and REST APIs.

Experience with microservices and event-driven architecture.

Hands-on experience with Kafka and at least one enterprise messaging technology.

Strong understanding of API security, OAuth 2.0, TLS, and encryption.

Experience with Jenkins, Maven, Gradle, GitHub, SonarQube, and CI/CD.

Experience with automated unit, integration, behavioural, and performance testing.

Production-support experience using enterprise monitoring and logging tools.

Proven ability to lead technical delivery and coordinate engineering activities.

Preferred Skills

Banking, payments, cards, digital wallets, alerts, or account-servicing experience.

Experience With Cassandra, MariaDB, Or Other NoSQL Platforms.

Experience with Apigee or another API-management platform.

Familiarity with AWS, Pivotal Cloud Foundry, or Google Cloud.

Knowledge of Autosys and enterprise batch scheduling.

AWS certification or another relevant cloud certification.

Experience using AI-assisted software-development tools.
