  • Implement automated testing frameworks using TDD, BDD, JUnit, Cucumber, and mocking libraries.
  • Collaborate with cross-functional teams (cloud engineering, data engineering, architecture, QA, and product) to deliver secure, compliant financial systems.
  • Enhance system reliability through observability, logging, metrics, and performance tuning.
  • Participate in code reviews, architectural discussions, and continuous improvement initiatives.
  • Ensure adherence to financial‑industry standards for security, auditability, and operational excellence.

 

Required Qualifications

  • 5–7+ years professional experience as a Software Engineer or Backend Engineer.
  • Strong proficiency in Java 21, Spring Boot, RESTful APIs, and microservices.
  • Hands-on experience with AWS, including EMR, Spark, S3, Lambda, CloudWatch, or related services.

  • Demonstrated experience with TDD, BDD, Cucumber, and automated testing frameworks.
  • Experience working in regulated environments or large-scale enterprise systems.
  • Familiarity with CI/CD pipelines, Git, Jenkins, GitLab, or similar tooling.

 

Preferred Qualifications

  • Experience in financial services, fintech, risk systems, or high‑throughput transaction platforms.
  • Knowledge of Kafka, Kinesis, or other streaming technologies.
  • Exposure to DevOps practices, infrastructure-as-code, or containerization (Docker, Kubernetes).
  • Understanding of domain-driven design (DDD) and event-driven architectures.
  • Performance tuning experience for low-latency, high-volume systems.
