  • Collaborate with Product Owners, Architects, DevOps, QA, and other cross-functional partners.
  • Work within Agile delivery practices and contribute to engineering best practices.
  • Support CI/CD efforts and application modernization initiatives.
  • Design and optimize database structures, queries, and stored procedures for relational database environments.

  • Proven background designing and developing microservices-based solutions.
  • Experience creating and supporting REST APIs.
  • Strong database skills with Oracle or SQL Server, including SQL, schema design, query optimization, stored procedures, and performance tuning.
  • Experience with Git, Maven or Gradle, Jenkins, and SonarQube.
  • Ability to collaborate effectively, solve problems proactively, and communicate clearly across technical and non-technical teams.
Preferred Skills
  • Exposure to Azure services such as Azure Kubernetes Service, Azure Functions, Azure Service Bus, Azure App Services, Azure DevOps, or Azure Key Vault.
  • Experience with Docker and Kubernetes.
  • Familiarity with Kafka, RabbitMQ, or other messaging technologies.
  • Knowledge of API gateways and event-driven architectures.
  • Understanding of OAuth and JWT-based security practices.
  • Experience with cloud-native or distributed system development.
  • Background supporting enterprise applications in modern engineering environments.
