• 3-6 years of experience in DevOps, DevSecOps, or Platform Engineering, with a strong focus on CI/CD pipeline development for application delivery
• Hands-on experience with Terraform for provisioning and managing infrastructure
• Experience integrating automated testing (unit, integration, API) and security/quality checks (e.g., SAST, DAST) into CI/CD workflows
• Experience working across multi-stack environments (backend, frontend, data pipelines)
• Experience collaborating with engineering teams in Agile environments
• Proficiency in scripting (Python, Bash, or similar)
• Experience with CI/CD tools (GitLab CI/CD, Jenkins, AWS CodePipeline, or similar)
• Working knowledge of AWS cloud-native architectures (e.g., Fargate, Lambda, API Gateway)
