Job description

The program seeks a senior database administrator to own steady-state administration of its on-premises database estate, which continues to operate in a monitored hybrid enclave while the program migrates workloads to an Azure Government environment. The estate has two administration tracks: SQL Server databases, administered end-to-end through SQL Server Management Studio, and the MariaDB databases supporting the on-premises ServiceNow instance, hosted on Red Hat Enterprise Linux (RHEL) 9.8 servers and administered over SSH (command-line; no GUI tooling assumed). The primary focus of this position is on-premises database administration. Candidates who will also continue the incumbent's support to the cloud migration should additionally meet the requirements in the final section.

Section 1 - On-Premises Database Administration (Primary Focus)

Responsibilities

• Administer production SQL Server databases through SQL Server Management Studio: backup and recovery (including periodic restore verification), performance tuning, index and statistics maintenance, security and permission management, capacity and health monitoring, and patch coordination through program change control.
• Administer the MariaDB databases supporting the on-premises ServiceNow instance on RHEL 9.8 hosts over SSH: service health, logical and physical backups, user and grant management, configuration and log review - Linux command-line administration.
• Maintain the database inventory and documentation: configurations, backup and retention schedules, and tested recovery runbooks.
• Operate within program change management; record administrative actions and evidence per policy.
• Support incident response for database-layer issues and participate in the on-call rotation [if applicable - confirm with program office].
• Sustain the legacy estate through the hybrid-enclave period, including eventual decommission, final backup, and archival tasks as systems retire or migrate.

Required Qualifications

• Five or more years administering production SQL Server databases: backup/restore, security, performance tuning, and routine maintenance.
• Hands‑on MariaDB or MySQL administration from the Linux command line, including SSH‑based administration of RHEL hosts; comfort in PowerShell and Windows Server environments for the SQL Server estate.
• Scripting for administrative automation (PowerShell; T‑SQL; bash for RHEL‑side tasks).
• DoD 8140/8570 IAT Level II baseline certification (for example, Security+ CE), or ability to obtain within the contract‑required window.
• Active DoD Secret clearance, or eligibility per contract requirements.
• Disciplined change‑management habits and clear written documentation.

Desired

• Familiarity with the ServiceNow platform's data layer; experience operating in DoD or Army enclaves; database monitoring tooling; deeper RHEL administration (systemd service management, dnf patch coordination, SELinux awareness).

Section 2 - Additional Scope: Cloud Migration Support

If the position also continues the incumbent's support to the program's Azure Government cloud migration, the following additional requirements apply.

• Familiarity with Azure Government environments and Azure data services, in particular Azure SQL Managed Instance - the program's landing target for SQL Server workloads.
• Exposure to database migration assessment and execution: Data Migration Assistant, Azure Database Migration Service, and backup/restore‑based cutover patterns, including schema and compatibility remediation.
• Ability to work within a DevSecOps pipeline discipline: changes promoted through automated gates, with artifacts and evidence produced per release.
• Understanding of estate disposition planning: not every database migrates - some workloads retire or are replaced by enterprise services - and the administrator supports those decisions with accurate inventory and data‑handling.
• Desired certifications: Microsoft DP-300 (Azure Database Administrator); AZ-900.

Experience with centrally provisioned Army cloud environments is a plus.
