We're 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 who s moved past tutorials and has real scars from production systems. You don t 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.

You'll work alongside senior engineers on a team that's 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 you'll be doing real work from day one, with mentorship and context from engineers who've built these systems before.

A note on what we're not looking for:

This role isn't for someone who's 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 isn't the right fit. If it sounds interesting and you want to learn it properly, we'd love to talk.

• Assist with deployment and maintenance of on-premises compute, storage, and networking infrastructure alongside our AWS environment
• Participate in bare metal server provisioning and OS deployment workflows
• Support day-to-day network operations: troubleshoot connectivity issues, help maintain firewall rules, VLANs, and VPN configurations under senior guidance
• Help maintain and document storage systems and cloud connectivity configurations

• Write and maintain Infrastructure as Code using Terraform and Ansible for both on-prem and cloud resources
• Support CI/CD pipeline maintenance and help onboard teams to existing platform tooling
• Assist with Kubernetes cluster operations — deployments, troubleshooting, resource management — across bare metal and EKS environments
• Contribute automation scripts and tooling improvements in Python or Bash

• Follow established security standards for on-prem and cloud: help maintain RBAC configurations, apply patches, and support access management processes
• Participate in on-call rotation with support from senior engineers; help investigate and resolve infrastructure incidents
• Contribute to monitoring dashboards and alert configuration across hybrid environments

• Work closely with senior engineers and application teams to understand infrastructure needs and translate them into tickets and tasks
• Keep runbooks, wikis, and operational documentation current as you learn systems
• Flag issues, ambiguities, and potential improvements — your observations from ground-level operations matter

• 3–5 years of experience in infrastructure, Dev Ops, platform engineering, systems administration, or a related role
• At least one full-time industry role beyond your first job (internships and co-ops count toward the foundation, but we re looking for professional experience in a production environment)
• Comfortable with Linux system administration: file systems, networking, process management, bash scripting
• Hands-on experience with at least one IaC tool — Terraform or Ansible preferred
• Working knowledge of AWS fundamentals: EC2, VPC, IAM, S3, and basic networking concepts
• Basic networking understanding: IP addressing, DNS, VLANs, firewalls — you don t need to configure BGP from scratch, but you should be able to troubleshoot a connectivity issue
• Experience with or exposure to Kubernetes — doesn t need to be bare metal, but you should understand the basics of pods, deployments, and services
• Scripting ability in Python or Bash for automation tasks

• Any exposure to physical…
