Site Reliability Engineer (all genders)

As Site Reliability Engineer (all genders) you will join a deeply technical squad of around 6 engineers responsible for the reliable operation and infrastructure behind the Intelligent Grid Platform (IGP). The platform runs across 100+ customer instances on Kubernetes, spanning Azure, Open Telekom Cloud, and on-premise environments. You design, build, and maintain the platform foundation: cluster provisioning, deployment pipelines, observability, secrets management, and infrastructure-as-code. You partner closely with the new Operations team that will run IGP day to day for customers, providing them with the tooling, monitoring, and automation they need to operate confidently. You work in a squad together with other SREs, reporting to the Engineering Manager.

• You develop and maintain infrastructure-as-code (Terraform, SaltStack) to manage 100+ customer instances with layered configuration
• You design and maintain observability (monitoring, alerting, SLOs) so that production issues surface early and are resolved quickly
• You own and evolve secrets management, certificate automation, and security tooling across the platform
• You reduce operational toil through automation, better tooling, and solid runbooks
