Platform & Infrastructure Engineer

LG Ad Solutions • Denver, CO

4d • $112,000 - $176,000 • Hybrid

About The Position

We are growing our infrastructure team and looking for an engineer who has experience with both physical infrastructure and cloud environments. This role involves working in a hybrid environment that spans data centers and AWS. You will work alongside senior engineers on the team, provisioning servers, managing network infrastructure, extending IaC practices, and ensuring system reliability. This is a role where you will be doing real work from day one, with mentorship and context from experienced engineers.

Requirements

• 3–5 years of experience in infrastructure, DevOps, 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.

Nice To Haves

• Any exposure to physical infrastructure: data center work, homelab, or on-prem environments in a professional setting.
• Familiarity with configuration management tools (Ansible, Salt, or similar).
• AWS certification (any level) or in-progress certification.
• Experience with observability tooling: Prometheus, Grafana, Datadog, or ELK.

Responsibilities

• 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.

Benefits

• 100% employer-paid medical, dental, and vision coverage for employees and eligible dependents.
• Company-paid life and AD&D, STD and LTD insurance, plus optional supplemental coverage.
• 401(k) with company match.
• Flexible Time Off (FTO).
• Paid parental leave.
