• Develop Jenkins pipelines and automation using Groovy where required.
• Work with container technologies such as Docker and Amazon ECS.
• Support AWS services including Lambda, DynamoDB, and Fargate.
• Address vulnerabilities, security requirements, compliance-related upgrades, and platform maintenance activities.
• Investigate issues reported by internal engineering teams and provide technical solutions or workarounds.
• Identify and fix bugs within internal developer tools and automation platforms.
• Collaborate with software engineers, platform engineers, DevOps teams, and other technology groups.
• Participate in rotating assignments involving customer support, debugging, platform development, and maintenance.
