Collaborate with development, infrastructure, and release management teams to ensure smooth deployment operations and production readiness.
Troubleshoot and resolve deployment, automation, and release-related issues across distributed and mainframe environments.
Contribute to CI/CD platform governance, security, reliability, and operational excellence.

Strong development experience in C# with the ability to build and optimize deployment automation within Octopus Deploy.
Experience designing, testing, and deploying production-ready release automation solutions.
Deep understanding of DevOps principles, Infrastructure as Code, deployment orchestration, and release management best practices.
Understand configuration as code, RBAC, and working within the Mainframe environment from modern deployment platforms
Experience with DevOps tools, platforms, and interfaces: Jenkins, UCD, Github, Github Actions, JFrog Artifactory, Hashicorp Vault, Ansible, Octopus Deploy
Proficient with Java, Python, Typescript, Groovy, YAML, NPM
Experience with deploying to cloud platforms: OCP, Azure, AWS
