About The Position

Eagle Wireless is hiring a Senior Infrastructure Engineer to own and standardize the compute platform used across the company. The platform includes physical servers and storage at company sites, AWS accounts, virtual machines and clusters, containers, Linux systems used by engineers, and backup and recovery. The role is based on-site in Minneapolis, Minnesota; Solon, Ohio may be possible for the right candidate. It involves regular travel to sites in North America and occasional travel to Europe and APAC. The technology stack includes Proxmox, AWS, Ubuntu and RHEL/Rocky, Podman, Ansible, and Axcient. The engineer will build and maintain on-premises compute and AWS infrastructure, manage virtualization and container services, provide Linux support for engineering teams, and establish repeatable automation, monitoring, backup, and recovery practices. The role also requires documenting infrastructure standards, coordinating with application owners and network staff, cross-training with a compute engineer in Belgrade, and preparing production change plans with validation and rollback steps. Architecture is reviewed by the CISO before it ships.

Requirements

At least 7 years of experience in infrastructure or systems engineering, including recent ownership of a hybrid on-premises and cloud environment.
Expert-level Linux administration with Ubuntu and RHEL/Rocky, including systemd, shell scripting, package management and repositories, networking, performance troubleshooting, and users, sudo, and SSH at scale.
Experience with storage on hypervisor hosts using ZFS or LVM-thin, including capacity monitoring and disk failure recovery.
Proven experience supporting engineers across many Linux systems, including build machines, test systems, and developer escalations.
Hands-on experience with virtualization on Linux and AWS; AWS services include EC2, VPC, IAM, and S3.
Backup and recovery experience, including personally performed restores and recovery after VM or host failure.
Configuration management with Ansible and scripting in Bash, PowerShell, or Python.
Container experience with Docker or Podman and systemd.
Habit of documenting diagrams, standards, and runbooks that others can follow.
Degree or equivalent relevant experience.
Windows Server administration.
Working knowledge of firewalls, routing, VPN, and DNS/DHCP.

Nice To Haves

Experience with reverse proxies and certificate management, including nginx and Traefik.
Experience with rootless Podman and systemd Quadlets.
Experience with Axcient and Proxmox Backup Server.
Proxmox clustering experience, including quorum and Corosync failure scenarios.
Infrastructure as code experience with Terraform.
Kubernetes and Helm experience.
Experience with ELK (Elasticsearch, Logstash, Kibana) and Grafana.
Experience running Jenkins and Gerrit instances.
Entra ID single sign-on and federation experience with SAML and OIDC.
Experience supporting manufacturing or engineering workloads.

Responsibilities

Manage on-premises servers, hypervisor hosts, storage, and UPS systems, including racking, cabling, out-of-band management, and NAS storage.
Manage hardware lifecycle, capacity planning, patching, failed-disk replacement, and data recovery.
Build the compute foundation for the new Solon factory and headquarters.
Manage AWS accounts, regions, EC2, storage, ECR, account lifecycle, and AWS health and abuse notices.
Manage on-premises and AWS virtual machines and clusters, including Proxmox installations, VM standards, P2V and physical-server rehosting, and AWS image imports.
Own and test infrastructure backup and recovery using Axcient, Proxmox Backup Server, drive imaging, and AWS image restores; include DHCP, DNS, and firewall configurations in backups.
Harden Linux and Windows servers owned by IT.
Manage the container platform, including rootless Podman with systemd Quadlets, Portainer, the private registry, and service deployment standards.
Provide Ansible-based deployment with least-privilege access so application teams can deploy without IT involvement.
Manage reverse proxies and certificates, including nginx, Traefik, SSL issuance and renewal, and standards for publishing applications.
Install Linux servers and provision users, sudo, and SSH keys; define processes for developer requests for root access, build machines, and test VMs.
Provide operating-system-level Linux support to engineers for build machines and test systems, including packages, networking, storage, and performance.
Stand up and operate instances behind internal services such as Jenkins, Gerrit, PyPI, and FTP/EDI; application teams own their projects and pipelines.
Develop infrastructure as code and Bash, PowerShell, and Python scripts to make provisioning and routine operations repeatable.
Implement platform logging, monitoring, and dashboards using ELK and Grafana.
Support single sign-on for platforms hosted by IT, in coordination with the IT administrators who own identity.
Write infrastructure standards in Confluence as a deliverable of the role.
Maintain a clear division of responsibilities with application owners: the role runs the platform, while application owners run what is on it.
Cross-train as a backup with the compute engineer in Belgrade.
Build and host DNS, NTP, proxy, and DHCP servers, and back up their configurations; coordinate with the network team, which operates those services and owns connectivity between sites and AWS.
Use sufficient network knowledge to troubleshoot firewalls, routing, VPN, DNS, and DHCP and keep the core network running during an outage.
Prepare production change plans with validation and rollback steps.
Submit architecture for CISO review before implementation.
