• Integrate Keycloak-based Single Sign-On (SSO) authentication with Jenkins.
• Implement and manage a secure credential management framework for Jenkins (secrets, tokens, certificates).
• Develop custom tools, scripts, and automation to accelerate and standardize migration activities.
• Upgrade Jenkins agents from Java 17 to Java 21, ensuring compatibility and stability.
• Collaborate with platform, security, and application teams to validate migrated pipelines and workflows.
• Perform troubleshooting and performance tuning post-migration.
• Create detailed documentation, runbooks, and architecture diagrams.
• Conduct knowledge transfer sessions and provide operational handover to support and engineering teams.

• Strong hands-on experience with Jenkins (CloudBees and/or FOSS Jenkins).
• Proven experience leading or executing CI/CD platform migrations.
• Solid understanding of Jenkins architecture: controllers, agents, plugins, and shared libraries.
• Experience running Jenkins on Linux-based virtual machines and Kubernetes.
• Proficiency with Java (especially Java 17 and Java 21 compatibility considerations).
• Experience integrating Jenkins with SSO solutions, preferably Keycloak.
• Strong scripting skills (Groovy, Bash, Python, or similar).
• Experience with credential and secrets management best practices.
• Familiarity with Git-based SCM systems (GitHub, GitLab, Bitbucket).
• Strong troubleshooting, documentation, and communication skills.

Preferred / Nice-to-Have Skills

• Experience with Kubernetes-native CI/CD patterns.
• Knowledge of infrastructure-as-code tools (Terraform, Ansible, Helm).
• Familiarity with enterprise security and compliance requirements.
• Experience with monitoring/logging tools (Prometheus, Grafana, ELK, etc.).
• Prior experience working in large-scale enterprise or regulated environments.

What Success Looks Like

• Successful migration of Jenkins controllers and pipelines with minimal downtime.
• Secure, scalable, and well-documented FOSS Jenkins environments.
