This role sits within Deltatre's Group Office Management function - a distributed team operating across the UK, North Macedonia, India, and Italy that keeps our offices, front-of-house, and staff experience running to a consistent standard. The London office is Deltatre's UK base and hosts client meetings, senior visitors, and cross-office collaboration; how it feels and how it runs matters to how the business is experienced by people who walk through the door.

As Office Manager, you own the day-to-day operations of the Central London office, and you lead a small team spanning UK. It is a player-coach role: you cover reception and front-of-house yourself, run the office administration end-to-end, coordinate offshore colleagues, and line-manage the UK Office and Events Assistant. Reporting to the Group Head of Office Management, you're the primary point of contact for the office and the escalation point when something needs attention.

You have run a busy office before, and you know that the visible work (front-of-house, meeting rooms tidy) sits on top of a much larger volume of invisible work (suppliers, escalations, budget, logistics). You keep the standards high without needing to be told. You are calm under pressure - the hour before a client visit, the day the coffee machine breaks, the evening a staff event is on and something is delayed - and you know how to bring a small team along with you across time zones without micromanaging.

Required

• Prior experience in receptionist, PA, office management, or comparable administrative role
• Demonstrated experience managing or coordinating a small team - including remote or offshore colleagues
• Demonstrated ability to work in a busy office environment and prioritise across competing demands
• Clear written and verbal communication - including comfort communicating across time zones
• Organisational and planning skills with attention to detail
• Ability to use initiative and remain composed under pressure
• Intermediate or advanced proficiency in Microsoft Word, Excel, and Outlook
• Must be able to work onsite in Central London 5 days per week - no remote working option
• Fluent written and spoken English

Valued

• Broader Microsoft 365 knowledge (Teams, SharePoint, OneDrive administration)
• Data and AI-Driven approach
• Experience coordinating events and staff experience programmes
• Familiarity with sustainability reporting or ESG metrics tracking
• Experience in a distributed, multi-country office function
• Experience with travel booking platforms and meeting room / desk booking tools
