The Opportunity

Were growing our infrastructure team in Denver and looking for an engineer who has gotten their hands dirty with both physical infrastructure and cloud environments someone whos moved past tutorials and has real scars from production systems. You dont need to have all the answers yet but you should be able to own a task end-to-end ask good questions and learn fast in a hybrid environment that spans data centers and AWS.

Youll work alongside senior engineers on a team thats actively building out our on-premises layer provisioning servers managing network infrastructure extending our IaC practices and keeping everything running reliably. This is a role where youll be doing real work from day one with mentorship and context from engineers whove built these systems before.

A note on what were not looking for:

This role isnt for someone whos only worked in fully managed cloud environments and wants to stay there. The on-prem side of this team is real and growing if physical infrastructure sounds boring or intimidating this probably isnt the right fit. If it sounds interesting and you want to learn it properly wed love to talk.
