Infrastructure Architect - AWS

We are looking for a Principal Infrastructure who can command, design, and operate a globally distributed production environment across the US, UK, and AU regions. This role is for an architect-level engineer who still loves to get their hands dirty — the kind of person who can both lead a SRE/DevOps team and SSH into a production node to trace issues.
About the Role
This role involves end-to-end control of our multi-region infrastructure (AWS + on-prem hybrid) spanning compute, VoIP, databases, monitoring, and automation.
Responsibilities
Reliability and uptime for mission-critical communication systems handling millions of SIP sessions and HTTP requests daily.
Management and mentorship of DevOps/SRE and Support Engineers, ensuring process maturity and on-call readiness.
Responsibility for performance, scalability, and security across all environments.
Decision authority on infrastructure architecture, cost optimization, and modernization initiatives.
