Platform & Infrastructure Engineer

LG Ad SolutionsLG Ad Solutions is a global leader in connected TV (CTV) and cross-screen advertising. We pride ourselves on delivering state-of-the-art advertising solutions that integrate seamlessly with today's ever-evolving digital media landscape.The OpportunityWe'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.ResponsibilitiesHybrid InfrastructureAssist with deployment and maintenance of on-premises compute, storage, and networking infrastructure alongside our AWS environmentParticipate in bare metal server provisioning and OS deployment workflowsSupport day-to-day network operations: troubleshoot connectivity issues, help maintain firewall rules, VLANs, and VPN configurations under senior guidanceHelp maintain and document storage systems and cloud connectivity configurationsAutomation & Platform SupportWrite and maintain Infrastructure as Code using Terraform and Ansible for both on-prem and cloud resourcesSupport CI/CD pipeline maintenance and help onboard teams to existing platform toolingAssist with Kubernetes cluster operations — deployments, troubleshooting, resource management — across bare metal and EKS environmentsContribute automation scripts and tooling improvements in Python or BashSecurity & ReliabilityFollow established security standards for on-prem and cloud: help maintain RBAC configurations, apply patches, and support access management processesParticipate in on-call rotation with support from senior engineers; help investigate and resolve infrastructure incidentsContribute to monitoring dashboards and alert configuration across hybrid environmentsCollaborationWork closely with senior engineers and application teams to understand infrastructure needs and translate them into tickets and tasksKeep runbooks, wikis, and operational documentation current as you learn systemsFlag issues, ambiguities, and potential improvements — your observations from ground-level operations matterRequirements3–5 years of experience in infrastructure, DevOps, platform engineering, systems administration, or a related roleAt 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 scriptingHands-on experience with at least one IaC tool — Terraform or Ansible preferredWorking knowledge of AWS fundamentals: EC2, VPC, IAM, S3, and basic networking conceptsBasic 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 issueExperience with or exposure to Kubernetes — doesn't need to be bare metal, but you should understand the basics of pods, deployments, and servicesScripting ability in Python or Bash for automation tasksNice to HaveAny exposure to physical infrastructure: data center work, homelab, or on-prem environments in a professional settingFamiliarity with configuration management tools (Ansible, Salt, or similar)AWS certification (any level) or in-progress certificationExperience with observability tooling: Prometheus, Grafana, Datadog, or ELKLG Ad Solutions provides equal work opportunities to all team members and applicants, and it prohibits discrimination and harassment of any type on the basis of race, color, ethnicity, caste, religion, age, sex (including pregnancy), national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by our policies or federal, state, or local laws.We want to ensure that our hiring process is accessible.
