A BS or MS in Computer Science, Computer Engineering, or Information Technology is a plus, but practical experience matters more to us. Required Skills: •A fleet of ~60 HPE ProLiant DL360 Gen9/Gen10 bare-metal servers and ~100 virtual machines running RHEL-family Linux (currently Oracle Linux 9). •Virtualization: ~50 VMs on VMware, moving to a new platform this year, and a KVM/libvirt environment running the remaining ~50 VMs, which serve as Kubernetes nodes managed by DevOps. •Core infrastructure services: BIND, LDAP, mail relay, SFTP, and Foreman. •Self-hosted applications and database servers the product teams depend on: GitLab Self-Managed Premium, MariaDB, PostgreSQL, and MongoDB. These are yours at the system level; application and DBA-level tuning stay with the teams that use them. •Operational tooling: inventory (NetBox), monitoring (LogicMonitor / Site24x7 / Grafana), vulnerability management (Tenable One), automation hub (Ansible Automation Platform), backups (Veeam). •The physical environment: a six-rack private colo cage in Somerville, MA, including spare-parts inventory and hardware lifecycle tracking. •Routine network operations, such as wiring and top-of-rack switch port configuration. Major network reconfiguration and network device patching sit with our network engineering partner. •Keep the fleet current and consistent: patch, harden, and upgrade Linux servers on a controlled cadence through managed repositories and staged rollouts, and install, upgrade, and maintain the applications and database servers to vendor guidance — largely through Ansible roles and playbooks you write and the Ansible Automation Platform you operate. Qualifications: •Must be authorized to work in the United States (unfortunately, we cannot sponsor visas). •Join a company shaping the future of competitive and market intelligence. •Interface directly with a collaborative, high-performing team that values creativity, experimentation, and measurable results. •Competitive salary, benefits, and professional growth opportunities. •Own a real production environment end to end, on supported enterprise platforms with vendor backing. •Regular team offsites and opportunities for cross-functional collaboration.
