• Experience with or strong interest in Infrastructure as Code (IaC) and automation for network configuration and lifecycle management (e.g., GitHub, Terraform, Ansible).
• Ability to lead initiatives and coordinate teams during new office rollouts, complex changes, and incident response.
• Strong problem‑solving skills, ownership mindset, and ability to work in cross‑functional, multicultural teams.
• Intermediate English (spoken and written), with the ability to participate in meetings and collaborate with global teams.

Nice to Have

• Familiarity with Zero Trust network concepts and security‑driven networking.
• Experience with cloud networking (e.g., connectivity to public clouds) and hybrid environments.
• Experience with security mindset and encryption topics (e.g., secure protocols, network segmentation), even if not your primary specialization.
• Prior experience in distributed or global organizations.
