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
