Bonhams is seeking a Systems Administrator to join the Infrastructure & Sys Ops team in New York. This is a hands‑on, mid‑level infrastructure role within a small, collaborative global IT team, supporting approximately 1,250 users company wide across a modern hybrid enterprise environment. The role encompasses Microsoft 365 E5 services, Microsoft Intune, Azure infrastructure, Windows and macOS endpoints, enterprise networking, and the technology that underpins Bonhams’ live auction program.

The successful candidate will serve as the lead Systems Administrator for Bonhams’ New York operations, taking ownership of endpoint, identity and core infrastructure services while working closely with colleagues across North America, Europe and Asia to deliver secure, reliable and consistent IT services. The role offers the opportunity to influence infrastructure standards, contribute to global technology projects, and play a key role in supporting one of the world’s leading auction houses.

This position requires someone who is proactive, technically curious and comfortable taking ownership of technical issues from investigation through to resolution. The successful candidate will contribute to the continuous improvement of Bonhams’ global IT environment through automation, security hardening, documentation, monitoring, process improvement and the adoption of emerging technologies, including AI‑enabled services.

A key part of the role is supporting Bonhams’ live auction events, both within the New York and other US salerooms and at external venues. These events are business‑critical and require a calm, methodical approach to troubleshooting in time‑sensitive situations where system availability directly impacts the business. Additional after‑hours work associated with auction delivery and infrastructure changes will be required from time to time.

Applications will be accepted until August 14, 2026.
