• Strong scripting skills (Python and/or Bash).
• Experience with infrastructure‑as‑code tooling (Terraform, Ansible).

• Monitoring and observability tools (Prometheus, Grafana, ELK, Splunk).
• Experience managing vendor relationships or external cloud providers.

• Small, flat, collaborative team where your impact will be direct and visible.
• Flexible, hybrid working setup with opportunities to grow your skills in both technical and financial domains.
