Information Technology Operations Specialist

ATG connects thousands of auction houses, listing millions of items worth over $15 billion annually to buyers in over 170 countries around the world. These buyers generate over 100 million bids a year for our sellers, helping them achieve maximum value for the goods they sell. We help auctioneers sell everything from medieval swords to combine harvesters, paintings and decorative art through to classic cars, furniture, and Caterpillar forklifts. We do this through 8 marketplaces that leverage our online auction technologies. We make auctioneers more efficient; we make small companies big by bringing them access to millions of bidders they could never find on their own, and we bring them technology they could never afford alone. We bring bidders choice of unique and specialized items, convenience, and trust. And we do it all in a shared success model that accelerates growth of the circular economy and sustainable buying. With ATG, our buyers and sellers win but so too does the planet!

What we are looking for:

ATG is looking for an IT Operations Specialist who wants to do more than keep the lights on. You will contribute to a close knit, seasoned team that owns the IT experience for everyone in the business; from the moment a new hire logs in on day one to ensuring our systems run reliably at scale. As the connective tissue between IT and the rest of the organisation, you will work directly with Human Resources, Information Security, Finance, and Engineering to make sure technology enables rather than obstructs. We are not looking for someone to sit in a ticket queue. We are looking for someone who spots a broken process and fixes it, who reaches for a script before repeating a manual task, and who takes pride in an IT environment that just works. If you want to build something better and have the technical foundation and curiosity to do it, this is your role.

What you will do:

• Automation & Process Improvement: Identify and implement opportunities for task automation to reduce manual, repetitive work. Contribute to the development and maintenance of scripts (e.g. Python, PowerShell) to streamline IT operations. Document repeatable solutions, standard operating procedures, and user-facing how-to guides.
• Endpoint & Infrastructure Operations: Provide support to users in-person and remotely, resolving issues within agreed SLAs. Log, triage, update, escalate, and resolve support tickets using the ITSM platform. Install, configure, and maintain endpoint hardware including laptops, desktops, mobile devices, printers, and AV/conference equipment. Support and maintain Windows and macOS environments, including patching, upgrades, and software deployments. Monitor and maintain system stability, backup integrity, and endpoint compliance.
• Identity, Access & Onboarding: Manage user accounts, permissions, and group memberships in an Identity Provider. Conduct IT inductions and hardware provisioning for new starters, ensuring a consistent and high-quality onboarding experience. Manage the full joiners, movers, and leavers (JML) lifecycle for IT access and assets. Maintain accurate asset records and support the hardware refresh and decommissioning process. Support security hygiene by identifying stale accounts, enforcing MFA enrollment, and escalating access anomalies to the Security team. Administer and support Microsoft 365 services including Teams, SharePoint, OneDrive, and Exchange. Support the configuration and ongoing management of SaaS platforms and identity providers. Assist with the integration and troubleshooting of internal systems and tooling.
• Incident & Problem Management: Support incident response for internal systems by reproducing issues, validating fixes, and documenting resolution patterns. Understand and communicate the business impact of system downtime or degraded services. Escalate systemic or high-impact risks early and proactively.
• Cross-Functional & Project Support: Work closely with Information Security, Human Resources, Finance, and Engineering teams to ensure compliant and efficient service delivery. Assist in IT project execution, following defined processes and contributing to agreed timelines. Liaise with third-party vendors and suppliers for support, procurement, and warranty cases. Occasionally support out-of-hours tasks when required.

Who you are:

• 1–3 years of IT support or IT operations experience in a corporate environment.
• Strong working knowledge of Windows and macOS desktop environments.
• Experience administering Microsoft 365.
• Familiarity with endpoint management platforms (e.g. Intune, Jamf, or equivalent MDM tools).
• Solid understanding of networking fundamentals: TCP/IP, DNS, DHCP, VLANs, Wi-Fi.
• Experience managing the user lifecycle (joiners, movers, leavers) in an identity provider.
• Ability to follow and maintain IT documentation, asset registers, and SOPs.
• Strong troubleshooting methodology with the ability to isolate, diagnose, and resolve issues systematically.
• Foundational scripting skills, particularly PowerShell or equivalent, for task automation.
• Experience with ITSM/helpdesk platforms (e.g. Jira Service Management, ServiceNow, Freshservice).
• Familiarity with SSO, MFA, and RBAC principles within an identity provider.
• Exposure to cloud platforms: Microsoft Azure and/or AWS.
• Relevant certifications such as CompTIA A+, Microsoft MD-102, AZ-900, or equivalent.
• Experience supporting Apple hardware (MacBooks, iPhones, iPads) in a managed environment.
• Awareness of IT security principles, patching cadences, and compliance requirements.
• Demonstrated ability to take ownership of project tasks end-to-end, driving delivery to completion with minimal supervision.
