We are seeking a DevOps Engineer to support and maintain our Single Sign-On (SSO) service. You will ensure reliable authentication, identity federation, and smooth integration with downstream systems. Knowledge of infrastructure as code, CI/CD, and secure access patterns is essential.
• Maintain and operate the SSO service (authentication, authorization, token lifecycles, session management).
• Monitor reliability, performance, and security; implement alerting and incident response processes.
• Manage identity providers (SAML/OIDC), metadata exchange, and federation configurations.
• Collaborate with developers and security teams to implement identity-related features and fixes.
• Ensure secure secret management, key rotation, and certificate handling.
• Maintain IaC for SSO infrastructure and related components; implement reproducible environments.
• Develop and maintain CI/CD pipelines for SSO deployment, migrations, and rollbacks.
• Document architecture, runbooks, and standard operating procedures.
• Perform on-call rotation and post-incident reviews; drive continuous improvement.
We look for big thinkers. People who can drive positive change, step up and show what’s next – people with passion, can-do attitude and a hunger to learn and grow. In practice this means:
• This role requires Linux proficiency and experience operating services on Linux-based environments.
• 3+ years in platform/DevOps or SRE roles with SSO or identity-related work.
• Strong experience with Terraform and infrastructure automation.
• Proficiency with GitLab CI/CD or similar pipelines; experience automating builds, tests, and deployments.
• Familiarity with IAM concepts, SAML, OIDC, OAuth, and federation mechanisms.
• Experience with cloud platforms (e.g., AWS, GCP, Azure) and secure secret management.
• Scripting skills (e.g., Bash, Python) for automation and tooling.
• Strong problem-solving, communication, and collaboration skills.
Nice to have:
• Experience with LDAP/AD, SCIM, or enterprise identity providers.
• Knowledge of security hardening, auditing, and compliance practices.
• VM orchestration and related tooling.
