• Create custom integrations, plugins, bots, and SSO/LDAP connectors
• Harden, secure, and monitor platforms with TLS, OAuth2, RBAC, and Zero Trust principles
• Troubleshoot and support complex platform deployments
• Collaborate with DevOps, AppSec, and engineering teams
• Document everything from architecture and configuration to custom builds

WHAT YOU NEED TO BE SUCCESFUL

• Strong hands-on experience with Docker & Kubernetes in live production environments
• Experience with Linux systems, network configuration, and firewalls
• Familiarity with CI/CD pipelines and tools (GitOps, ArgoCD, Helm)

• Join a critical programme making a real-world impact
• 12-month+ contract with hybrid flexibility
