You will collaborate closely with product managers, quantitative analysts, business analysts, and engineering leads to deliver scalable, resilient, low-latency, and cloud-ready solutions leveraging Java, Spring Boot, and enterprise SQL databases.
Key Responsibilities
1. Architecture, Design & Engineering
- Design, build, test, deploy, and maintain robust applications leveraging Java microservices.

- Assume end-to-end ownership of software deliverables across the full Software Development Life Cycle (SDLC)-from technical design and implementation to automated testing, deployment, and post-release support.
- Drive iterative delivery using Agile/Scrum methodologies, actively contributing to sprint planning, backlog refinement, architectural reviews, and sprint demonstrations.
- Champion Test-Driven Development (TDD) and automated testing across unit, integration, and contract testing suites using frameworks such as JUnit, Mockito.
4. DevOps, CI/CD & Platform Modernization
- Integrate automated builds, static code analysis (SonarQube), security vulnerability scanning, and automated deployment pipelines into enterprise CI/CD workflows (GitHub, TeamCity/Jenkins, Harness/uDeploy).
- Participate actively in platform modernization initiatives, including microservice containerization (Docker, Red Hat OpenShift / Kubernetes) and cloud-ready architectures.
5. Production Support & Operational Excellence
- Partner with Level 3 Application Support and DevOps teams to triage and resolve production incidents, conduct Root Cause Analyses (RCAs), and implement permanent preventive remediations.
- Integrate observability, telemetry, health metrics, and structured logging (Prometheus, Grafana, Splunk / ELK) to ensure high availability, resilience, and operational transparency.
