hirify.global operates critical infrastructure supporting genomics pipeline and clinical laboratory systems.

What you will do

• Act as the designated backup for the primary infrastructure lead and assume full operational control of data center, network, and server environments during absences, emergencies, or transitions.
• Administer and maintain physical and virtual server infrastructure (Windows Server, Linux, VMware/Hyper-V), including provisioning, patching, monitoring, and capacity planning to sustain 99.9%+ uptime.
• Manage LAN/WAN networking operations (switches, routers, firewalls, VLANs) to maintain high availability and security across on-premises systems.
• Build and continuously improve runbooks, network diagrams, and disaster recovery documentation to reduce mean time to recovery and eliminate single points of failure.
• Support on-premises genomics pipeline infrastructure by ensuring compute and storage resources meet clinical laboratory throughput and availability requirements.
• Respond to infrastructure incidents and outages, including after-hours escalations, and collaborate with bioinformatics, clinical lab, and IT teams to align reliability with patient-impacting workflows.

Requirements

• 7+ years of hands-on enterprise IT infrastructure engineering experience in a complex, predominantly on-premises environment.
• Deep expertise in physical and virtual server administration (Windows Server 2016/2019/2022, Linux) including VMware vSphere or Microsoft Hyper-V.
• Strong networking fundamentals: routing, switching, VLANs, firewall policy management, and systematic network troubleshooting (Cisco, Palo Alto, Fortinet, or equivalent).
• Experience managing physical data center environments (rack/stack, structured cabling, power, and cooling awareness).
• Proficiency with SAN/NAS storage and enterprise backup/recovery systems (Veeam, Commvault, or equivalent).
• Must be authorized to work in the United States; visa sponsorship is not available.

Nice to have

• Experience in healthcare, clinical laboratory, genomics, or other regulated life sciences environments.
• Relevant certifications (CCNA/CCNP, VCP-DCV, MCSE, CompTIA Network+/Security+, or equivalent).
• Exposure to HIPAA compliance, NIST frameworks, or SOC 2 audit environments.
• Scripting proficiency (PowerShell, Bash, or Python) for infrastructure automation.
• Experience with monitoring platforms (PRTG, SolarWinds, Zabbix, or similar).

Culture & Benefits

• Hybrid work model: most work can be done remotely, with the requirement to be able to come on-site to the Houston location when needed.
• Operational resilience focus: emphasis on zero unplanned outages attributable to single-person dependency and strong documentation/runbooks.
• After-hours availability required for scheduled maintenance windows, incident response, and emergency infrastructure coverage.
• Compliance-driven environment with regulatory requirements applicable to clinical laboratory operations.

Hiring process

• Internal hiring process with direct candidate relationship management.
• Interviews and evaluation of infrastructure ownership, documentation discipline, and incident response capability.
