Cynaxus is hiring a Level 3 Infrastructure Engineer for our escalation engineering practice — the engineer other engineers call when they are out of road. This is a tier-3 role by design: no ticket triage, no password resets, just the problems that stalled everyone below you.
About the role
You have been the key infrastructure lead inside an organization of 250+ employees — the person who owned the environment, not a slice of it — and you carried problems the full route: symptom, hypothesis, isolation, root cause, fix, and the documentation that kept it fixed. Here you will do that across multiple client environments under our managed-services and escalation engagements, in Azure, AWS, VMware, or compatible infrastructure platforms.
What you'll do
Take the escalations our clients' tier-1 and tier-2 teams cannot close — the intermittent storage latency, the broken identity federation, the cluster that fails over wrong, the network path nobody can trace. Own each one end-to-end and hand back a documented root cause and runbook, so the same problem never escalates twice. Lead infrastructure workstreams in client projects: virtualization refreshes, hybrid connectivity, capacity and resilience design. Carry on-call responsibility within a senior rotation that respects your time because everyone in it is senior too.
What you bring
Proven tenure as the lead infrastructure engineer in at least one 250+ employee organization, with end-to-end ownership of incidents and architecture. Deep hands-on expertise in at least one of Azure, AWS, or VMware — and real working competence in another. Current certifications are required and applications without them will not be considered: Azure Administrator/Solutions Architect, AWS Solutions Architect or SysOps, VMware VCP or above, or directly comparable. An eager learner's posture and a sharp diagnostic mind — the platforms will change; the discipline cannot. Clear written communication, because your runbooks become the client's institutional memory.
What we offer
Escalation work only — the interesting problems, none of the queue. Senior peers across security, cloud, and endpoint who pick up when you call. Compensation that reflects tier-3 depth. US-based, remote-first culture.
