Staff Systems Administrator (5996)

What You'll Do:

• Infrastructure Ownership (On-Prem & Cloud)

• Own and operate on-premises and cloud infrastructure, including physical and virtual servers, storage, backup platforms, identity services, core network services, and enterprise applications.

• Administer Azure and/or AWS environments with responsibility for availability, capacity, performance, monitoring, secure configuration, backup, and disaster-recovery readiness.

• Define technical roadmaps, identify operational risks, and independently drive modernization, standardization, scalability, and resilience improvements.

• Maintain accurate architecture diagrams, inventories, operating procedures, recovery documentation, configuration records, and service ownership information.

• Plan and execute infrastructure changes using disciplined change, testing, rollback, and post-implementation review practices.

• Firewalled Entity and Segmented-Environment Support

• Operate technology services for a dedicated legal or operating entity with explicit separation of systems, identities, data, administration, suppliers, and access from other corporate environments where required.

• Implement and maintain approved trust boundaries, network segmentation, firewall policies, secure remote access, administrative tiers, and controlled cross-entity connectivity.

• Ensure data, devices, accounts, cloud resources, and third-party access remain within authorized entity, contractual, regulatory, and data-residency boundaries.

• Partner with Security, Legal, Compliance, Privacy, and corporate IT teams to translate entity-specific obligations into practical controls, operating procedures, and evidence.

• Document and periodically validate boundary controls, data flows, privileged access paths, exceptions, and intercompany dependencies; escalate gaps and drive remediation to closure.

• Support local business continuity and operational autonomy while aligning with approved global architecture, security standards, and governance.

• Security, Compliance, and Systems

• Establish, implement, and maintain secure configuration baselines for Windows, macOS, Linux, servers, network devices, cloud services, and endpoint-management platforms using recognized frameworks and vendor guidance.

• Own patching and vulnerability-remediation workflows, including asset coverage, risk-based prioritization, remediation timelines, exception documentation, validation, and status reporting.

• Administer and validate endpoint protections such as full-disk encryption, EDR/XDR, host firewall, secure boot, application controls, device compliance, removable-media controls, and least-privilege configurations.

• Harden identity and administrative access through role-based access control, multifactor authentication, privileged-access separation, conditional access, service-account governance, and periodic access reviews.

• Maintain logging, alerting, time synchronization, configuration monitoring, backup protection, and security telemetry needed for detection, investigation, and auditability.

• Collect and maintain audit-ready evidence; support internal and external audits, control assessments, security reviews, customer requirements, and remediation plans.

• Participate in incident response, containment, recovery, root-cause analysis, and corrective actions for infrastructure and endpoint security events.

• Manage technical risks and policy exceptions transparently, including compensating controls, accountable owners, expiration dates, and closure plans.

• Identity, Endpoint, and Service Delivery

• Manage Windows, macOS, and Linux endpoints through Intune, Jamf, or equivalent tooling, ensuring secure provisioning, configuration compliance, software deployment, inventory accuracy, and timely retirement.

• Administer Active Directory and Entra ID or equivalent identity platforms, including user and group lifecycle, authentication, authorization, federation, and policy enforcement.

• Lead onboarding and offboarding activities, including device provisioning, access configuration, license assignment, asset recovery, and compliance validation.

• Provide advanced troubleshooting and escalation support for employees, engineering systems, lab environments, collaboration services, and secure connectivity.

• Own IT asset lifecycle, software licensing, vendor coordination, procurement support, warranty management, and secure equipment disposal.

• Use scripting and automation to improve consistency, reduce manual effort, strengthen controls, and provide meaningful operational and compliance reporting.

• Contribute reusable infrastructure patterns, standards, and documentation that can scale across comparable international entity environments.
