Information Technology Department:

Stream’s IT team delivers modern, secure technology solutions that power our global operations. We combine proactive management, rigorous cybersecurity, and agile software development to drive business growth. By aligning technology strategy with business goals, we keep Stream at the forefront of innovation and operational excellence.

The Role:

The Systems Administrator (Server Administration & Security) is responsible for the day-to-day administration, availability, and performance of Stream’s server environments across data center and cloud/hosted platforms. This role operates in the Day-2 operational space—monitoring, patching, hardening, troubleshooting, and continuously improving server reliability—while ensuring systems are installed and maintained to meet stringent security requirements.

You will partner closely with the Cybersecurity team to implement and validate security controls aligned to NIST guidance and CIS Benchmarks, maintain audit-ready evidence, and remediate vulnerabilities within defined service levels. Success requires strong Windows/Linux administration skills, disciplined change management, and the ability to balance operational uptime with secure-by-default configuration standards.

Key Responsibilities:

Operate and maintain server platforms (Day-2): Administer Windows and/or Linux servers, including provisioning support, configuration, monitoring, performance tuning, capacity planning inputs, and lifecycle maintenance.

Harden servers to approved baselines: Implement secure configuration standards and golden images aligned to CIS Benchmarks and internal hardening guides; ensure deviations are documented and risk-accepted where applicable.

Patch and vulnerability management: Plan and execute OS and firmware patching, coordinate maintenance windows, validate outcomes, and remediate vulnerabilities identified by scanning tools within defined SLAs.

Access control and privileged administration: Manage server access using least privilege, MFA where applicable, and privileged access workflows; perform periodic access reviews and ensure secure credential handling.

Endpoint/security tooling on servers: Deploy and maintain required security agents (e.g., EDR, configuration management, vulnerability scanners, logging collectors) and troubleshoot agent health and coverage gaps.

Monitoring, alerting, and incident response support: Maintain monitoring/alerting for server health and critical services; respond to incidents, perform triage and root-cause analysis, and coordinate recovery actions.

Configuration management and automation: Use scripting and automation to standardize builds, enforce desired state, and reduce operational toil (e.g., PowerShell, Bash, Ansible, SCCM/Intune, or similar).

Change, release, and maintenance governance: Follow change management processes; create implementation and rollback plans; document changes and ensure stakeholders are informed of risk and impact.

Compliance alignment (NIST/CIS/internal standards): Implement and validate required controls (logging, time sync, encryption, secure services, firewall rules, etc.); support audits by producing evidence and remediation plans.

Backup, restore, and disaster recovery readiness: Ensure backups are configured, tested, and monitored; perform periodic restore tests and participate in DR exercises for server services.

Standard documentation and runbooks: Create and maintain build standards, hardening checklists, operational runbooks, and troubleshooting guides; keep CMDB/inventory details current.

Continuous improvement of server security posture: Identify and remediate insecure configurations, reduce attack surface, implement baseline drift detection, and partner with Cybersecurity on new controls and security initiatives.

Success Metrics & KPIs:

Server availability and operational health: Improved service uptime, reduced recurring incidents, and consistent performance against monitoring/alerting targets.

Patch and vulnerability remediation performance: High patch compliance and timely remediation of critical/high vulnerabilities within agreed SLAs; minimal exception backlog.

Baseline hardening and configuration drift: Servers deployed and maintained to CIS/internal baselines; reduced drift and faster correction of non-compliant settings.

Security control coverage: High coverage/health of required security agents (EDR, logging, vulnerability scanning) and consistent log delivery to centralized platforms.

Audit readiness and compliance outcomes: Audit requests fulfilled with complete evidence; reduced repeat findings; clear remediation plans and documentation for exceptions.
