  • Support and enhance CI/CD pipelines for automated building, testing, and deployment.
  • Contribute to technical design discussions and ensure solutions align with platform and compliance requirements.
  • Create and maintain required technical documentation for developed components and system changes.
Required Qualifications

  • Bachelor's degree in Computer Science, Information Technology, or a related field (or equivalent professional experience).
  • Minimum of 7 years of experience as a programmer/analyst developing software in accordance with the Software Development Life Cycle (SDLC).
  • Proven experience developing cloud-based applications using Python.
  • Experience implementing Infrastructure as Code using AWS CDK (preferred) or Terraform.
  • Strong experience with AWS Step Functions for business process modeling and orchestration.
  • Experience developing modern front-end applications using Angular (TypeScript) (React acceptable as well).
  • Experience building container-based solutions using Docker.
  • Hands-on experience with CI/CD tools and Git-based workflows.
Preferred Technical Skills

  • Python
  • Angular Web UI (TypeScript)
  • AWS Lambda
  • AWS Step Functions
  • AWS DynamoDB
