Servers, VPN clients, endpoints, and a ticket queue — in the same day, and all of it yours.

Sienna Systems is seeking a hands‑on Infrastructure Support Specialist to join our Social Security Administration Special Notice Option (SNO) team in Alexandria, Virginia.

SNO is how SSA delivers notices to beneficiaries who need them in an alternate format — Braille, large print, audio, and data files. The systems you support are what get those notices processed, tracked, and out the door on time to people who cannot read a standard letter.

You will be the person who keeps the physical and virtual infrastructure running: servers, directory and authentication services, connectivity, endpoints, and the day‑to‑day equipment the program depends on. Small team, real ownership, direct contact with the government technical staff.

Why You'll Want This Role:

$70,000 – $75,000 based on experience
Established SSA program with a defined mission and a stable government customer
401(k) with 4% matching, immediate vesting, no restrictions
3 weeks Paid Time Off plus 11 Federal Holidays
Broad exposure across servers, virtualization, networking, and endpoints rather than one narrow lane

Key Responsibilities:

Administer, configure, maintain, and troubleshoot the infrastructure supporting SNO, including server platforms, directory services, authentication services, virtual environments, network connectivity, office productivity tools, and endpoint protection.
Administer and maintain operational equipment including local and remote connectivity, printers and peripherals, VPN connections, and the related hardware and software.
Build and configure desktops and workstations for program staff.
Troubleshoot escalated incidents and drive them to resolution, documenting tickets against service level agreements and escalation processes.
Support change management and process improvement, providing documented changes for review.
Coordinate with vendors and support technology planning and infrastructure lifecycle management.
Collaborate with government staff and other stakeholders supporting the program.

Required Qualifications:

Able to obtain and maintain a Public Trust suitability determination
At least 2 years of hands‑on IT infrastructure implementation experience
Experience with SCCM 2012 or later
Experience with VPN connectivity, including troubleshooting Cisco VPN router and client software
Experience with VoIP infrastructure
Strong understanding of TCP/IP and other networking principles
Knowledge of computer and network security systems, applications, procedures, and techniques
Working knowledge of incident management tools and help desk software applications
Familiarity with technical support practice including ticket documentation, service level agreements, statistics, and escalation processes
Excellent analytical, troubleshooting, and critical‑thinking skills
Strong command of spoken and written English
Solid organization, presentation, and documentation ability, including Visio diagrams and as‑built documentation

Preferred Qualifications:

Prior federal program experience or an existing federal suitability determination
ITIL Foundation, Network+, or Security+ certification
Vendor management and infrastructure lifecycle management (ITIL) experience
Familiarity with Section 508 accessibility standards
Understanding of change management, process improvement, and asset inventory principles

Salary: $70,000 – $75,000 based on experience

Company Benefits:

Medical/dental/vision insurance
401(k) plan: 4% matching, immediate vesting, no restrictions
Long- and short‑term Disability coverage
Company-sponsored Life Insurance coverage
