We’re hiring a top-tier Executive Assistant (EA) to support our CEO. This is not a traditional admin role, it’s a critical support function embedded in a fast-moving SaaS company with a strong commercial focus.

We’re looking for someone who understands the pace and rhythm of a sales-driven business and is comfortable working close to customers, investors, and strategic partners as part of your support. You'll help manage time, unblock execution, and ensure momentum across high-leverage priorities.

A background in sales, finance, commercial operations focussed industries would translate well here. You’ll thrive if you’re operationally sharp, people-savvy, and proactively driving outcomes behind the scenes.

• Handle logistics & ops: travel bookings, onboarding support, team dinners and offsites, conference coordination, vendor management, and general office logistics
• Champion internal culture: coordinate in-person and remote team events and celebrations
• Boost systems and productivity: use tools like Slack, Notion, G-Suite, and automation platforms to streamline workflows and reduce manual admin
• Support with personal admin: occasionally help with bookings, errands, and other life logistics that help free up executive focus

• Proactive and dependable, you anticipate what’s needed and handle issues before they escalate
• Clear communicator who builds trust with gravitas and experience to keeps things always moving forwards
• Comfortable navigating high-growth, fast-paced environments with shifting priorities
• You likely come from a sales, finance or commercial operations industry and you understand how to support founders or senior execs in externally-facing roles
• Confident coordinating external relationships with professionalism - from investors and advisors to vendors and partners
• A natural gatekeeper and thought partner, able to prioritise and create clarity amidst chaos
• You leverage tools and systems (e.g. Notion, Slack, G-Suite, Zapier) to make yourself and the people around you more productive
• Energised by the effect of a well-run day, week, or system can have on a whole company
  
  

• Competitive salary and meaningful equity
• 25 days annual leave (plus celebration days and your birthday off)
• Hybrid, flexible working from our London or New York office
• Learning & development budget for coaching, courses, and conferences
• ️ Private medical, dental, and vision cover
