- Strong Linux fundamentals and associated toolkit (bash, tcpdump, iptables, git).
- Experience building network automation using Python with Ansible and CI/CD on GitLab.
- A reliability-engineering mindset, including SLOs, observability, incident command, postmortems, and designing out toil.
- Fluent and critical use of AI in daily engineering, with a track record or credible ideas for applying AI to network operations.
