Get Access To All JobsAbout the Role
We are a dynamic IT consulting firm seeking an experienced Senior Systems Administrator to join our team. In this role, you won't just manage a single environment; you will take ownership of hybrid infrastructures across a diverse client portfolio.
This is not a "keep the lights on" role. We are looking for an engineer who brings a consultative mindset to every ticket and project—focusing on automation-first strategies, proactive monitoring, and robust security governance. You will act as a technical lead for on-premise storage and virtualization while managing AWS deployments and Identity Management stacks.
Beyond the technical execution, you will serve as a trusted advisor, partnering with clients to author and develop critical IT policies that ensure their data retention, disaster recovery, and security postures are mature and compliant.
Key Responsibilities
Multi-Client Infrastructure & Virtualization
- Architect, manage, and optimize virtualization environments across various client sites, with a heavy focus on VMware and Proxmox clusters.
- Manage and maintain high-availability storage systems across different hardware generations and vendors, specifically utilizing Synology, TrueNAS, and Dell Unisphere environments.
- Deploy and scale AWS resources for multiple tenants, ensuring cost-efficiency, proper segmentation, and security best practices.
Networking & Security
- Maintain and troubleshoot Intermediate-level networking across a multi-vendor stack. You must be comfortable navigating complex topologies involving Juniper switches, Meraki cloud-managed infrastructure, and Palo Alto firewalls.
- Serve as the primary administrator for Identity Providers, specifically Okta and Active Directory, managing SSO, MFA, and complex lifecycle management workflows.
- Audit client environments to enforce a Least Privileged Access model across all systems.
Automation & Proactive Monitoring
- Automate wherever possible. Utilize scripting and orchestration to standardize deployments and eliminate repetitive manual tasks across the client base.
- Own the central monitoring ecosystem, utilizing Zabbix to configure custom triggers, templates, and alerts that cater to specific client SLAs.
- Adopt a proactive stance on system health—identifying and resolving latency or capacity trends before they impact client operations.
Governance & Policy Development
- Collaborate directly with clients to write, develop, and maintain IT policies tailored to their specific business requirements.
- Focus on defining and testing Backup & Retention policies, Disaster Recovery (DR) planning, and Data Security standards.
Required Qualifications
- Experience: 5+ years of experience in Systems Administration
- Virtualization: Expertise managing VMware (vSphere/ESXi) and Proxmox VE, with the ability to adapt to other hypervisors as needed.
- Storage: Strong hands-on experience configuring and maintaining Synology NAS, TrueNAS Scale, and Dell Unisphere/Unity arrays.
- Networking: Proven ability to troubleshoot and manage Juniper routing/switching, Meraki wireless/security, and Palo Alto firewalls.
- Cloud & Identity: Experience managing AWS infrastructure and Identity Providers (Okta/Active Directory) in a multi-tenant context.
- Monitoring: Advanced configuration skills in Zabbix (creating templates, custom parameters).
- Consultative Skills: Ability to translate technical risks into business policies (DR, Backups, Security) for non-technical client stakeholders.
Desired Skills
- Experience migrating workloads between virtualization platforms (e.g., VMware to Proxmox).
- Scripting proficiency in Python or Bash for automation and Zabbix custom parameters.
- Experience with Infrastructure as Code (Terraform/Ansible) for standardizing client deployments.
Job Type: Full-time
Pay: $90,000.00 - $120,000.00 per year

- Dental insurance
- Health insurance

Get Access To All JobsTips for Finding Visa Sponsorship as a Senior Systems Administrator
Target employers with a history of H-1B filings
Large enterprises, universities, healthcare systems, and managed service providers file H-1B visa petitions for Systems Administrators regularly. Focusing on these employer types improves your odds of finding a role with genuine sponsorship intent.
Certifications strengthen your specialty occupation case
Microsoft, Cisco, and AWS certifications alongside a relevant degree reinforce that your role requires specialized knowledge. USCIS scrutinizes Systems Administrator petitions, so a strong credentials profile makes the specialty occupation argument easier to sustain.
Clarify the scope of the role before accepting an offer
Senior Systems Administrator roles vary widely. A position managing enterprise cloud infrastructure is more defensible as a specialty occupation than general IT support. Confirm the role involves complex systems engineering before relying on it for H-1B sponsorship.
Ask about L-1A and L-1B pathways if transferring internally
If you currently work for a multinational employer abroad, an intracompany transfer on an L-1 visa may be faster than H-1B. L-1B covers specialized knowledge workers, which applies to senior infrastructure and systems roles.
Understand the LCA's prevailing wage requirement
Your employer must file a Labor Condition Application certifying they'll pay the prevailing wage for your location and role. In competitive markets like San Francisco or New York, prevailing wages for senior systems roles are set at a high level.
Prepare documentation linking your degree to the role
USCIS may issue a Request for Evidence if your degree field does not directly match systems administration. Having a detailed job description, organizational chart, and degree equivalency evaluation ready in advance significantly reduces petition processing delays.
Frequently Asked Questions
Does a Senior Systems Administrator role qualify for H-1B sponsorship?
It can, but it requires careful framing. USCIS has issued RFEs on Systems Administrator petitions arguing the role does not always require a specific bachelor's degree. Senior roles focused on complex infrastructure, cloud architecture, or enterprise security are stronger candidates than generalist IT support positions. Your employer's attorney should document the degree requirement explicitly in the job description and LCA.
What degree do I need for a Senior Systems Administrator visa sponsorship?
Most employers require a bachelor's degree in Computer Science, Information Technology, Information Systems, or a closely related field. USCIS expects a direct relationship between your degree field and the job duties. If your degree is in an unrelated field, relevant certifications and a credential evaluation showing substantial coursework in computing can help support the petition, though approval is not guaranteed.
How can I find Senior Systems Administrator jobs that offer visa sponsorship?
Migrate Mate lists Senior Systems Administrator roles from employers actively willing to sponsor work visas, so you can filter specifically for sponsorship-open positions rather than guessing from generic job postings. This saves significant time compared to applying broadly and discovering late in the process that an employer does not sponsor.
Are Senior Systems Administrator H-1B petitions at higher risk of a Request for Evidence?
Yes, historically more so than software engineering roles. USCIS has questioned whether systems administration inherently requires a specific degree rather than general experience. RFE rates are lower for petitions that clearly document enterprise-scale complexity, specific technology platforms managed, and an explicit employer policy requiring a degree for the position. Premium processing, which adjudicates within 15 business days, is worth considering given this risk.
Can a Senior Systems Administrator get sponsored for a green card?
Yes. The EB-2 and EB-3 categories both cover this role. EB-3 is the most common pathway, requiring PERM labor certification to prove no qualified U.S. workers are available. EB-2 applies if the role requires an advanced degree or the employer can demonstrate exceptional qualifications. Processing timelines depend heavily on your country of birth, with Indian and Chinese nationals facing multi-year backlogs under current priority dates.
What is the prevailing wage requirement for sponsored Senior Systems Administrator jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
