The role covers compute, virtualization, storage, networking, identity, endpoints, and security tooling in standalone and air-gapped environments.\nThis is a hands-on senior individual contributor position. Responsibilities include racking and imaging hardware, building and hardening systems, automating repeatable work, troubleshooting difficult issues, and helping establish technical standards across sites. The engineer must be comfortable working independently, shifting across infrastructure disciplines when needed, and owning work from design through testing, documentation, and support.\nThe role sits between IT operations and accreditation. Systems must be secure, reliable, and ready for review by ISSMs and government assessors. Correct implementation the first time, backed by complete documentation and technical evidence, is an expected part of every build.\nWhat you'll do:\nBuild and operate classified infrastructure\nDeploy, configure, and sustain Windows Server and Red Hat Enterprise Linux systems, virtualization clusters, enterprise storage, and core infrastructure services in standalone and air-gapped enclaves.\nBuild and support VMware, Nutanix AHV/Prism, or similar virtualization environments. Nutanix experience is preferred.\nSupport high-density compute for AI/ML, simulation, and engineering workloads, including GPU node provisioning, performance troubleshooting, capacity planning, and coordination with facilities on rack space, power, and cooling.\nAdminister and support Active Directory, DNS, DHCP, Group Policy, PKI, certificate services, privileged access, and role-based access for isolated forests with no connection to corporate IT.\nBuild and maintain golden images and hardened baselines for servers, workstations, virtual desktops, and supporting infrastructure.\nManage patching, updates, software packages, and security content in disconnected environments through approved transfer and validation processes.\nAdminister backup, recovery, and continuity capabilities. Perform scheduled restore testing and document results and corrective actions.\nDesign, configure, and troubleshoot managed switching, VLANs, firewall rules, network segmentation, and approved network connections between facilities. Coordinate with network and security teams to maintain secure, supportable network standards.\nAutomate and standardize\nAutomate provisioning, configuration, patching, reporting, and compliance tasks using PowerShell, Ansible, Python, Terraform, or similar tools.\nCreate repeatable build processes, system baselines, checklists, and runbooks so systems can be deployed consistently rather than built by hand each time.\nImprove existing processes by reducing manual steps, preventing common errors, and documenting effective methods for building and supporting systems.\nApply and validate DISA STIGs and SRGs using SCAP, STIG Viewer, ACAS/Nessus, scripted remediation, and other approved tools.\nMaintain configuration-management records, as-built documentation, change records, and scan evidence so system configurations can be understood and defended later.\nReview technical changes before production implementation, with attention to security, availability, rollback planning, and operational impact.\nSupport accreditation and security operations\nWork with ISSMs, ISSOs, security teams, and program stakeholders to implement NIST SP 800-53, JSIG, RMF, and program-specific technical controls.\nProvide technical documentation and evidence for authorization packages, continuous monitoring, assessments, and audits.\nImplement and maintain audit logging and forwarding, including Elastic or similar centralized logging and SIEM tools.\nSupport vulnerability management through ACAS/Nessus scanning, findings triage, remediation planning, patching, and validation during approved maintenance windows.\nHelp resolve technical POA&M items and document remediation steps, validation results, and remaining risks.\nSupport approved media handling, file transfer, cross-domain processes, and contamination or spillage response alongside the security team.\nSupport users and sites\nAct as a senior escalation point for classified IT issues that block engineering work or require deeper troubleshooting across multiple systems.\nIdentify and correct root causes rather than relying on repeated fixes or workarounds.\nSupport user-account, privileged-access, and workstation-access requests consistent with least privilege and separation-of-duties requirements.\nSupport new facility and enclave stand-ups from rack layout and cabling through infrastructure deployment, user onboarding, and operational handoff.\nMentor junior system administrators and site IT staff, review implementation work before production release, and help improve team standards.\nWork independently, manage competing priorities, communicate risks early, and bring practical solutions to the team.\nRequired qualifications:\nStrong hands-on experience with Windows Server, Active Directory, Group Policy, DNS, DHCP, PKI, and enterprise endpoint management.\nExperience administering Red Hat Enterprise Linux or similar enterprise Linux systems.\nExperience with VMware, Nutanix, Hyper-V, or similar enterprise virtualization platforms. Nutanix AHV/Prism experience is preferred.\nExperience with enterprise storage, backup/recovery, and capacity planning.\nExperience with managed switching, VLANs, firewall administration, network segmentation, and troubleshooting network connectivity.\nExperience with PowerShell and infrastructure automation. Experience with Ansible, Python, Terraform, or similar tools is a plus.\nExperience applying DISA STIGs, using SCAP/STIG Viewer, supporting ACAS/Nessus findings, and working in RMF, NIST SP 800-53, JSIG, or similarly regulated environments.\nExperience operating in disconnected, air-gapped, classified, or highly controlled environments.\nAbility to document work clearly, follow change control, validate results, and build systems that are easy for others to support.\nAbility to work independently in a fast-moving environment, shift between infrastructure disciplines when needed, and make sound technical decisions without requiring detailed direction.\nPreferred qualifications:\nNutanix AHV, Prism Central, Files, Flow, or cluster lifecycle management.\nGPU server, AI/ML, simulation, VDI, or high-performance compute infrastructure.\nElastic, Splunk, or other centralized logging and SIEM platforms.\nDisconnected WSUS, offline patching, software-repository management, or approved media-transfer workflows.\nData-center buildouts, rack-and-stack, structured cabling, power/cooling coordination, and new-facility stand-ups.\nRelevant technical or security certifications, such as Security+, CISSP, RHCSA/RHCE, VMware VCP, Nutanix NCA/NCP, Microsoft certifications, or CCNA/CCNP.","description_format":"text","description_chars":6943,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI","Drone AI"],"lifecycle":[{"event":"open","at":"2026-09-26T21:41:58Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2","filings_12m":2,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":132500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":1,"p_active":0.612,"p_room":1,"age_days":24,"expected_fill_days":76,"reasons":["conf:3","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":140000,"is_top_pay":true},"html_url":"https://alion.io/job/shield-ai-senior-it-operations-engineer-r6117","json_url":"https://alion.io/job/shield-ai-senior-it-operations-engineer-r6117.json","meta":{"generated_at":"2026-10-21T23:46:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":33930,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":50},"rest":"https://alion.io/mcp/rest/get_company?id=50"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fshield-ai-senior-it-operations-engineer-r6117"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fshield-ai-senior-it-operations-engineer-r6117"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fshield-ai-senior-it-operations-engineer-r6117"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/shield-ai-senior-it-operations-engineer-r6117\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fshield-ai-senior-it-operations-engineer-r6117"}]}
