What you’ll be doing
Engineering Delivery
- Design, build, test, and release Java microservices using Spring Boot for enterprise-scale platforms.

- Help resolve technical risks, dependencies, and blockers across multiple workstreams.
AI-Enabled SDLC & Engineering Governance
- Use AI-assisted tools responsibly to accelerate development cycles while applying governance and guardrails for security, IP control, and compliance.
- Apply GenAI techniques such as LLM-assisted development and prompt engineering under strict controls.
- Contribute to safe usage patterns for retrieval-augmented generation (RAG) and agent-based workflows with human-in-the-loop validation.
Quality, Security & Operational Readiness
- Implement unit, integration, and contract tests with strong coverage metrics (JUnit, Mockito, TestContainers).
- Ensure secure coding practices, vulnerability management, and observability (logs, metrics, traces).
- Deliver production-ready services supporting reliability and compliance requirements.
Collaboration
- Work closely with Tech Leads, QA, SRE, architects, and platform teams to integrate microservices across business-critical systems.
- Foster a culture of continuous improvement and inclusive team collaboration.

- CI/CD pipelines and tooling (Jenkins/GitLab, Sonar, SAST/DAST).
- Strong test automation experience (JUnit, Mockito, TestContainers).
- Hands-on experience with cloud (GCP) deployment models.
✔ Familiarity with GenAI concepts, LLM use cases, RAG/agent-based patterns, and governance principles.
✔ Ability to make pragmatic decisions under tight deadlines while maintaining quality standards.
Desirable
- Exposure to regulated financial services environments with strict controls.
- Experience with containerized deployment, Kubernetes, and modern observability stacks.
- Prior work implementing AI-enabled SDLC practices responsibly with governance.
