Senior payment gateway integration engineers in São Paulo run roughly $48–$70/hr. 8K–18K senior integration/RPA/Zapier engineers. 3–5 week senior hiring loop; tax-and-payroll complexity for foreign hires. Operating timezone: BRT (UTC−3).
2026 stack: Stripe (default global), Adyen (enterprise multi-region), Braintree/PayPal (consumer), Klarna/Afterpay (BNPL), Plaid (US ACH), GoCardless (UK/EU SEPA). 3DS2 + SCA mandatory in EU. Multi-payment-provider routing via Spreedly or in-house. Payment engineers must reason about idempotency keys, webhook delivery guarantees, dispute/chargeback flows, and PCI-DSS scope minimization (tokenization, redirects). Naive integrations leak PAN data to backend logs and trigger expensive PCI audits.
Where São Paulo senior payment gateway integration talent comes from: São Paulo senior talent flows from Itaú + Bradesco + Banco do Brasil banks, Nubank, Mercado Livre, Stone + StoneCo, Globo, plus USP + UNICAMP + PUC-SP CS programs. LatAm largest tech market — fintech + e-commerce + consumer-tech depth. For payment gateway integration specifically, this means buyers can typically tap engineers who have shipped at one of these orgs before — relevant operational depth, not bootcamp graduates.
Our payment gateway integration team delivers a full range of capabilities tailored to São Paulo's FinTech & Digital Banking and E-commerce & Marketplace sectors:
Full Stripe integration — Checkout, Elements, Payment Intents, Subscriptions, Connect, Invoicing, and Billing Portal. We handle the complexity so you get a seamless payment experience.
Recurring billing with free trials, proration, plan changes, cancellation flows, dunning for failed payments, and usage-based metering.
Accept credit cards, debit cards, ACH, Apple Pay, Google Pay, PayPal, bank transfers, and regional payment methods — all through a unified integration.
Split payments between your platform and sellers using Stripe Connect. Handle onboarding, identity verification, payout schedules, and tax reporting.
Our integrations use tokenization and Stripe Elements to minimize your PCI scope. No sensitive card data touches your servers.
Reliable webhook handlers for all payment events — succeeded, failed, refunded, disputed. Idempotent processing ensures no duplicate charges or missed events.
Each phase ships with written progress notes plus a weekly review call scheduled in your business hours. See our full process →
When choosing a payment gateway integration partner in São Paulo, look for a team with production experience in your specific industry. Generic developers miss critical domain nuances that cost you time and money in rework.
