Accounting always runs from behind. The transactions you process already happened, so the only way to keep clients with up-to-date financials is to never fall behind. The moment you do, quality slips, and the slip compounds.
That's the real test of this role. Not whether you know what a journal entry is (you do). It's whether you can stay organized across 8 to 12 startup clients, chase down the document you're missing instead of waiting for it to land in your inbox, and keep the whole thing moving.
This is the first Staff Accountant Prescient is hiring in Mexico City. It's a foundational hire, not a backfill. You'll be the first person on this level, working alongside the Controller until the team grows under you.
Why we're hiring this role now
Prescient is preparing for a wave of new clients coming onboard. The Controller is currently doing this transactional work directly, and they need a first Staff Accountant to own it so they can step into more of an oversight role as more accountants get hired behind you.
What's in it for you
You'll start by completing the QuickBooks ProAdvisor training (structured, self-paced, available in English or Spanish), then move into a structured onboarding on Prescient's processes and tools led directly by the Controller. From there you build a real career in U.S. startup accounting.
The workload is balanced on purpose. The first two weeks of each month are the heavy stretch (transactions, then payroll), while the back half of the month runs slower. Prescient doesn't overload anyone; when the pace picks up, they hire to offset it rather than piling it on one person.
Because you're the first hire at this level, you'll have outsized influence on how the function takes shape. The processes exist but are still being tested, so you'll help refine them, and strong performers take on senior responsibilities as the firm scales.
What you'll do
Process accounts payable: review, code, and enter vendor invoices and manage payment runs
Process accounts receivable: generate client invoices, apply cash receipts, follow up on outstanding balances
Run daily and weekly bank and credit card reconciliations in QuickBooks Online
Maintain accurate general ledger entries and code transactions to the correct accounts
Support month-end close: prepare journal entries, reconcile balance sheet accounts, document workpapers
Coordinate payroll processing (inputs to Gusto or a similar platform), two to three times a month
Chase missing documents from clients and keep client files organized in Google Drive
What success looks like
Month-end close completed within 5 business days of month-end
Reconciliations are clean, documented, and reviewable with no outstanding items
Low error rate and fast turnaround once you're past your first two months
Proactive communication with your manager when issues arise, no surprises
Team and reporting
You'll report to and work alongside the U.S.-based Controller, who reviews your work and is the face of client communication, so you won't be running client meetings. The structure today is Owner, CFO, Controller, then this role. As Prescient grows the plan is to add more Staff Accountants beneath you, with the Controller moving into oversight. Communication is mostly async over Slack and email, with one team meeting a week to share wins, blockers, and stay aligned.
You're a fit if you have
Must-haves
2 to 4 years of accounting experience covering AP, AR, and month-end close
Proven proficiency with QuickBooks Online as your primary tool
Strong understanding of accrual-basis accounting
Genuine organization across multiple clients and deadlines at once
A proactive mindset: you go find the missing document, you flag the blocker, you don't wait to be chased
Intermediate English, written and verbal, enough to communicate clearly with a U.S.-based manager over Slack and email
Comfort working independently and adapting quickly as processes change
Based in the Mexico City metropolitan area
Nice-to-haves
Experience with U.S.-based clients or familiarity with U.S. GAAP
Experience with AP and expense platforms: Bill.com, Ramp, Brex, Expensify, or Gusto
Familiarity with U.S. payroll accounting (stock options, equity comp, payroll taxes)
Multi-client or public accounting firm experience
University degree in Accounting (Licenciatura en Contabilidad)
Experience with Notion, Asana, or similar project management tools
