Summary
DevOps/SRE-style role maintaining production Kubernetes on Talos Linux plus on-prem infrastructure (Proxmox, bare metal, Ceph), networking (BGP, DNS, VLANs, VPNs), and GitOps automation with Terraform, Ansible, GitLab CI, and Argo CD. Also manages databases, observability, PKI, and LoRaWAN/IoT field devices.
Description
We are looking for someone who feels comfortable working with both Kubernetes and physical hardware. For us, DevOps doesn’t stop at pipelines—it extends to the server room, the network, and field devices.
