What the job involves

• We are looking for a Senior Reliability Engineer with focus on Identity and Access Management (IAM) to join the Corporate Engineering team
• As an SRE together with other engineers you will be responsible for the continuous operation, further development and enhancement of Planet’s corporate infrastructure and applications, acting as the technical authority for our enterprise identity ecosystem
• This is a full-time, hybrid role which will require you to work from our Berlin, Haarlem or Ljubljana office 3 days per week
• Help to ensure the operation of Planet’s internal IT systems, specifically architecting and maintaining our identity providers (Okta, Auth0, Keycloak)
• Improve existing and create new solutions by engineering automated zero-day Joiner, Mover, and Leaver (JML) workflows directly from our HRIS (e.g., HiBob)
• Scripting & Tooling: Use Python or Go to automate repetitive tasks, build custom provisioning connectors for legacy applications, and enforce identity data minimization
• Identify and reduce operational toil through automation, making our systems self-healing and predictable
• Infrastructure as Code (IaC): Leverage APIs, Terraform, Ansible, or SaltStack to manage configurations as code, moving away from manual UI/CLI changes across our identity platforms
