About ShipOffers

ShipOffers is a global 3PL fulfillment and logistics provider, offering product sourcing, warehousing, and shipping services across the United States and Europe. We operate 5 offices across Colorado, Nashville, and Amsterdam, with warehouse operations powered by Warehance, a WMS platform we helped design and build.

Our technology stack is fully cloud-based: Microsoft 365, Google Workspace, AWS, Ubiquiti UniFi networking, and Zebra label printing across all warehouse locations. We run no on-premises servers.

As we scale, we are hiring our first dedicated IT Systems Administrator to build our identity and device management infrastructure from the ground up, the right way, cloud-native from day one.

Role Overview

This is a greenfield role. There is no existing Active Directory, domain controller, or MDM in place. You will design and implement our entire identity, device management, and network access infrastructure from scratch, then own and operate it going forward.

You will report directly to leadership and work on-site at our Englewood, CO headquarters, with remote responsibility for offices in Nashville and Amsterdam.

This role is the right fit if you are energized by building clean infrastructure from nothing, can operate independently, and understand both office IT and warehouse/operations environments.

Key Responsibilities

Identity & Access Management

Select, deploy, and own our cloudnative IdP — JumpCloud or Microsoft Entra ID (evaluation in progress)
Implement SSO across Microsoft 365, Google Workspace, AWS, and internal tools
Enforce MFA across all users and systems
Build rolebased access control (RBAC) and manage onboarding/offboarding workflows
Configure RADIUS authentication for Ubiquiti UniFi WiFi tied to user identity
Ensure EU data residency compliance for Amsterdam office (GDPR)

Device Management (MDM)

Enroll and manage all endpoints: 35 Macs, 60 Windows PCs across 5 locations
Push and enforce baseline security policies: disk encryption, patching, screen lock, software compliance
Handle zerotouch provisioning for new device deployments
Manage full hardware lifecycle: procurement, imaging, asset tracking, secure offboarding
Support warehouse floor devices, including shared workstations and kiosk configurations

Print Infrastructure

Rationalize and standardize label printing across all warehouse locations (Zebra ZPL printers, IPaddressed)
Evaluate and implement a cloud print routing solution (PrintNode, QZ Tray, or native WMS integration) to eliminate manual PDF print workflows
Maintain printer mappings and network print configurations across all sites

Network Infrastructure

Administer Ubiquiti UniFi environment across all 5 offices: switches, APs, firewalls, and site VLANs
Manage and monitor sitetosite connectivity
Maintain VPN and secure remote access
Troubleshoot network and connectivity issues across distributed locations

Internal IT Support

Serve as primary IT support across all locations for hardware, software, access, and connectivity
Support warehouse operations staff as well as office employees
Manage software licensing and SaaS tool administration

Security & Compliance

Implement endpoint security policies and patch management
Monitor access logs and identify anomalies
Establish GDPRcompliant data handling for the Amsterdam office
Document and maintain security baseline across all sites

Documentation & Process

Build and maintain infrastructure documentation from day one
Document network architecture, identity policies, and device standards
Develop and own the IT runbook for onboarding, offboarding, and incident response

Required Qualifications

4+ years in IT systems administration
Handson experience with cloudnative identity platforms: JumpCloud, Microsoft Entra ID (Azure AD), or equivalent
Experience managing both Windows and macOS endpoints
Experience with MDM platforms (Intune, JumpCloud, Jamf, or Kandji)
Ubiquiti UniFi networking administration
Comfort owning infrastructure independently with minimal oversight
Strong documentation discipline

Preferred Experience

Multisite IT experience (managing users and devices across geographically distributed offices)
Warehouse or operations environment IT support (floor devices, label printers, shared terminals)
Zebra printer administration and ZPL label workflows
Google Workspace and Microsoft 365 coadministration
AWS IAM and cloud infrastructure familiarity
GDPR awareness or experience supporting EU office locations
Experience with print management solutions (PrintNode, QZ Tray, PaperCut)

What We’re Looking For

We want someone who:

Builds systems correctly from the start, not just fast
Understands that warehouse operations IT is different from corporate IT — and knows how to support both
Takes full ownership without needing to be told what to do next
Communicates clearly with both technical and nontechnical teammates
Is energized by a blank canvas, not intimidated by it

Compensation

$90,000 – $120,000 depending on experience

Benefits include:

Health benefits
Exposure to a global fulfillment and logistics infrastructure across 5 countries
Direct influence over architectural decisions in a fastscaling company
Growth opportunity as the IT function scales with the business
