We're now launching in the US and are looking for the first people to join our rocketship out of New York!

What you'll do

You'll spend your day verifying new merchant deals — ensuring that we onboard accurately first time, ultimately giving our customers a great first impression. If a process wasn't followed or data is incomplete, you'll catch it.

This is focused, deep-work admin that rewards pattern recognition. You'll be comfortable handling high volumes as we expand — 20 to 50 deals a day on average. The work suits people who genuinely find satisfaction in spotting what others miss and in getting through a long list cleanly.

You'll spend very little time on the phone with customers or in meetings. It's a role that allows for focus and flow rather than rapidly switching context.

Main responsibilities

  • Review 20–50 merchant onboarding cases daily.

  • Cross-check details across our CRM, signed contracts, and external registries (Companies House and similar).

  • Flag inconsistencies, missing information, or anything that doesn't add up.

  • Keep records clean, tidy, and audit-ready.

  • Spot patterns — if the same issue keeps appearing, surface it so we can fix the upstream process.

  • Work to a daily volume target without sacrificing accuracy.

Who you are

Skills & Attributes

  • Genuinely meticulous attention to detail — you're the person who notices the typo nobody else does.

  • Ability to stay focused on repetitive work for hours at a time without losing accuracy.

  • Strong pattern recognition — you'll quickly learn what a clean file looks like and spot what doesn't fit.

  • Comfortable working independently on a queue, with your own pace and rhythm.

  • Calm, methodical temperament — this role rewards consistency over speed-bursts.

  • Confident with screens and digital tools (we'll train you on ours).

Background

  • Fluent in English

  • Right to work in the US (visa sponsorship is not available for this role)

  • Able to work from our New York office 5 days a week
