The Role: Executive Assistant & Office Manager
We’re looking for an exceptionally organised, proactive, and high-energy Executive Assistant & Office Manager to support our CEO, founding team, and fast-growing London HQ.
This role blends classic EA support with light-touch office management — perfect for someone who thrives in fast-paced environments, cares deeply about details, and wants to operate at the heart of a high-growth company.
You’ll be the right hand to the exec team and the operational backbone of our London office — supporting scheduling, meetings, logistics, team coordination, and keeping our space running smoothly.
What You’ll Do
Executive Support:
* Calendar & Scheduling: Manage complex calendars for the CEO and founding team, balancing internal and external priorities
* Meeting Coordination: Prepare agendas, take notes, and ensure follow-ups happen across leadership meetings
* Internal Alignment: Help coordinate priorities, track OKRs, and keep the team moving in sync
* Stakeholder Engagement: Assist with investor communications, external meeting prep, and occasional deck support
* Travel & Offsites: Plan travel and coordinate logistics for company offsites and executive events
Office Management:
* Office Operations: Ensure the smooth day-to-day running of our London office (supplies, equipment, vendors, etc.)
* Culture & Events: Organise team lunches, socials, and onboarding kits to help foster connection and momentum
* Space Management: Liaise with the building, make the office a productive and inspiring space
* Vendor Coordination: Manage relationships with external service providers (cleaning, security, IT support, etc.)
* General Admin: Support ad hoc requests and keep operational documentation up-to-date
Who You Are:
* 3+ years experience supporting C-level executives in a high-growth or startup environment
* Prior experience managing a small office or team space is a plus
* Incredibly organised, detail-oriented, and resourceful - you anticipate problems before they happen
* Strong communicator, both written and verbal, and comfortable working with high-level stakeholders
* Reliable, trustworthy, and discreet when handling sensitive or confidential information
* Tech-savvy, fast learner, and excited to build systems and processes from scratch
* Energised by startups, fast-paced work, and ambitious teams - you bring positivity and calm under pressure
Why This Role?
* Operate at the core of a high-performing, high-growth company
* Make an outsized impact by supporting the people and processes that drive our business
* Build and shape an office and operational culture you’ll be proud of
* Work directly with world-class operators, engineers, and investors
* Grow with a company that’s scaling rapidly, sustainably, and globally
