Workplace & Event Operations Manager

Siro•New York, NY

2d•$145,000 - $165,000•Onsite

About The Position

Siro is hiring one person to own the operations behind its NYC workplace, team experiences, and conferences. The role runs the New York City office end to end, plans events that bring the team together, and serves as the operational right hand to the Director of Events for conferences and trade shows. This is an ownership role—not a coordinator role—with responsibility for budgets, vendors, outcomes, independent decision-making, and appropriate escalation. The Workplace & Event Operations Manager oversees the office’s visitor experience, facilities, space planning, supplies, food, atmosphere, vendors, budget, and operating systems. The role also plans and executes monthly socials, happy hours, holiday and seasonal events, milestone celebrations, company offsites, and new-hire welcome moments, including tracking expenses against event budgets and reconciling with finance. For conferences, the role manages booth construction and shipping, freight and materials, swag and collateral, travel and hotel logistics, show staffing, and vendor coordination. The position is based in NYC and requires working in the office four to five days per week.

At least 4 years of experience in workplace or office management, event operations, or hospitality.
Hands-on experience with conference logistics, including booth shipping, exhibitor services, room blocks, and on-site execution.
