About this role

Executive Assistant (Contract, Part-Time)

Umba is a fintech group building banking infrastructure for emerging markets.

We're looking for an experienced Executive Assistant to support our CEO on a part-time contract basis. This is a hands-on role with real ownership - you'll be the person keeping a demanding schedule coherent and making sure nothing falls through.

What you'll do

  • Own the CEO's calendar: scheduling, rescheduling, protecting focus time, and structuring the week so meetings are batched rather than scattered

  • Manage inbound email — triage, flag what needs attention, draft replies, and follow up on open threads

  • Coordinate meetings with investors, partners, and the executive team across US, Irish, and East African time zones

  • Support board and investor operations: scheduling, assembling quarterly update materials, and chasing inputs to deadline

  • Process expenses, invoices, and vendor and subscription renewals

  • Run research and prep work ahead of meetings: briefing notes, background on companies and people, agendas

  • Build lightweight systems and documentation as you go, so the role gets more efficient over time

  • What we're looking for

  • 3+ years supporting a founder, executive, or senior leader

  • Excellent written English and sound judgment about tone — you'll be corresponding on the CEO's behalf

  • Genuinely organised: you track commitments without being reminded and close loops before being asked

  • Comfortable with ambiguity and shifting priorities in an early-stage environment

  • Discreet, with experience handling confidential business information

  • Fluent with Google Workspace, Slack, and Notion

  • Based in New York City with availability to meet in person in Brooklyn or Manhattan

  • Nice to have: exposure to fintech, financial services, or venture-backed startups

  • Details

  • Contract, initially 3 months with the option to extend

  • Hybrid: mostly remote, with regular in-person time in Brooklyn

  • Start date: as soon as possible
