To build a new world of opportunity we bring together the brightest talent to help us build opportunities. We are entrepreneurs and believe in measuring success through results and growing within; talent and hard work never goes unnoticed. At Propel, we are here to change the way employees, customers and shareholders succeed together.

We are a team of passionate entrepreneurs, who foster curiosity and growth in our employees. Our culture is why we have been so successful and why our employees choose Propel to build their careers. It is also why we are one of North America’s fastest growing companies and a Best Place to Work.

Join us as we change the way employees, customers and shareholders succeed together.

About You:

You thrive in a vibrant, entrepreneurial organization where your ideas are valued. You are motivated by goals, a self-starter, and enjoy wearing multiple hats in a fast-growing fintech environment.

The Senior IT System Administrator is a senior technical owner within Propel IT, responsible for maintaining reliable, secure, documented, and healthy infrastructure, cloud services, endpoint platforms, identity services, and security-support processes. This hands-on role requires strong troubleshooting, disciplined change management, and clear communication with IT, Information Security, P&C, business stakeholders, and vendors. As an L3 escalation point, this person owns assigned systems and issues end to end, drives resolution, communicates proactively, and coaches junior team members through standards and practical troubleshooting guidance.

Responsibilities

Infrastructure, Cloud, and Network Operations

Administer, monitor, and improve Azure infrastructure, Entra ID, Azure networking, virtual machines, storage, resource health, access paths, and related cloud services
Manage and support Windows Server, AD DS, DNS, GPO, DFS, IIS, VMware, backup/recovery dependencies, and other core infrastructure services as assigned
Coordinate with vendors/MSPs for office network, firewall, switching, Wi-Fi, ISP, Azure, Cloudflare, and infrastructure work while retaining internal ownership of follow-up and closure
Support Cloudflare WARP, Zero Trust tunnels, access policies, network routing dependencies, and approved remote/private access paths in coordination with Security and system owners
Monitor system health, capacity, availability, backup posture, and configuration drift; identify issues before they become recurring support problems

Endpoint, Patch, and Device Management

Own day-to-day administration and health of endpoint management platforms such as Microsoft Intune, Microsoft Defender for Endpoint, KACE, Jamf, and any future macOS MDM replacement such as IRU/Kandji-style tooling
Deploy, monitor, and validate operating system patches, application updates, configuration profiles, security baselines, compliance policies, and endpoint remediation scripts
Support Windows Autopilot, Intune enrollment, Jamf enrollment, device rebuilds, endpoint readiness checks, BitLocker/FileVault, LAPS, ScreenConnect, Cloudflare WARP, KACE, and Defender onboarding
Investigate device issues affecting employee productivity, including hardware failures, application problems, update/reboot issues, browser and extension issues, and endpoint-policy conflicts
Maintain accurate runbooks for device onboarding, rebuild, patching, quarantine, remediation, and return-to-service workflows

Security Operations and Incident Support

Review, triage, and escalate security alerts from Microsoft Defender, Rapid7, KACE, Intune, Entra sign-in logs, Cloudflare, and related systems according to Propel security and compliance processes
Work with Information Security on suspicious activity, compromised-device investigations, risky sign-ins, malware alerts, phishing-related endpoint activity, and data-loss or DLP-triggered events
Gather and preserve evidence through approved tooling, including Defender investigation packages, Live Response where authorized, full scan results, logs, timelines, affected-device scope, and remediation evidence
Support containment actions when approved, including device isolation, session revocation, access blocking, password/MFA recovery actions, device wipe/rebuild, and controlled return-to-service validation
Document incident actions, approvals, evidence, and recovery steps in Jira or the approved security record without exposing unnecessary sensitive details to requester-facing comments

Microsoft 365, Identity, SSO, and Data Protection

Administer and support Microsoft 365 services including Exchange Online, Teams, SharePoint, OneDrive, Defender, Intune, Entra ID, enterprise applications, and related user/device policies
Understand and support SSO concepts including SAML, OIDC, enterprise apps, app assignments, claims, certificates, groups, MFA, Conditional Access, and break-glass/rollback considerations
Understand Microsoft Purview, DLP, information protection, retention, alerting, and email/data-flow controls sufficiently to troubleshoot issues and coordinate with Security, Legal/Privacy, and business owners
Support access lifecycle requests where delegated, while ensuring manager, system owner, Security, P&C, Legal/Privacy, CCB, or data-owner approvals are obtained where required

L3 Support, Coaching, and Escalation

Serve as the L3 escalation resource for complex endpoint, identity, cloud, network, infrastructure, and security-support issues that cannot be resolved by L1/L2
Coach L1/L2 team members on troubleshooting methods, evidence collection, ticket quality, customer communication, endpoint tooling, and when to escalate
Help resolve employee hardware and software issues when advanced technical support is needed, including situations involving policy conflicts, device compliance, account/session issues, or business-critical applications
Create and maintain practical support runbooks, checklists, knowledge articles, and escalation notes so recurring issues become easier for the team to handle

Change Management, Documentation, and Audit Readiness

Follow Propel change management and CCB processes for production, security, identity, endpoint, infrastructure, and business-impacting changes
Prepare accurate change summaries, implementation plans, rollback plans, validation steps, and post-change updates for assigned work
Maintain current documentation for architecture, access paths, configurations, administrative procedures, ownership boundaries, recurring checks, and operational standards
Participate in internal/external audits, user access reviews, security reviews, evidence gathering, policy remediation, and compliance-related improvement work
Ensure tickets and change records clearly show approvals, actions taken, validation results, remaining risks, and closure rationale

Requirements

College diploma or equivalent certification in Information Technology or related field
5+ years of progressive IT systems administration experience in a Microsoft enterprise environment
Hands-on experience administering Azure, Entra ID, Microsoft 365, Exchange Online, SharePoint, OneDrive, Teams, Intune, Defender, and Conditional Access or related identity/security controls
Strong working knowledge of Windows Server, AD DS, DNS, GPO, DFS, IIS, PowerShell, endpoint troubleshooting, and infrastructure operations
Experience with endpoint management and patching platforms such as Intune, Defender for Endpoint, KACE, Jamf, and macOS management tooling
Working knowledge of networking fundamentals, VPN/Zero Trust access, Cloudflare or similar access tooling, firewalls, switching, Wi-Fi, DNS, routing, and vendor/MSP coordination
Ability to troubleshoot complex user/device issues across hardware, Windows, macOS, Microsoft 365, browser, endpoint security, network, and application layers
Experience supporting security investigations, vulnerability remediation, endpoint containment/recovery, audit evidence, and compliance-driven technical work
Strong documentation, ticket hygiene, change-management discipline, and written communication skills
Experience with Rapid7, Microsoft Purview/DLP, Cloudflare Zero Trust, Azure networking, VMware, Dell hardware/storage/switching, ScreenConnect, and enterprise backup/recovery processes
Experience supporting SSO integrations, enterprise applications, SCIM/group-based provisioning, and third-party SaaS access models
Experience with ITIL-aligned support processes, Jira or Freshservice-style ITSM platforms, CCB/change governance, and audit-ready operational documentation
Scripting or automation experience with PowerShell and exposure to Python, Bash, Graph API, REST APIs, or infrastructure automation tools
Relevant certifications such as Microsoft Azure Administrator, Microsoft 365 Administrator, Security Administrator, Endpoint Administrator, Network+, Security+, ITIL, Jamf, or equivalent experience
