Now Hiring Ea

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 Umba
