Design and implement security controls and disaster recovery procedures.
Lead maintenance windows and infrastructure upgrades, coordinating with internal teams, exchanges and colocation providers.
Improve configuration management, monitoring and operational tooling using Ansible, Zabbix and Python.
Respond to incidents, identify root causes and implement improvements that strengthen resilience and performance.
What you’ll bring
Typically five or more years of experience supporting complex, mission-critical infrastructure.
Strong core and WAN network design expertise, with the ability to explain and justify your architectural decisions.
Deep hands-on knowledge of BGP, OSPF, firewall policies and packet-level troubleshooting.
Experience with multicast networking, including PIM and IGMP.
Hands-on experience across colocation and on-premises switching and connectivity.
Strong Linux skills, ideally with RHEL in high-performance environments.
Experience with infrastructure automation, configuration management and monitoring tools.
A proactive approach to identifying risks and opportunities for improvement.
Clear communication, sound judgement and the ability to remain composed during time-sensitive incidents.
