Senior payment gateway integration engineers in Barcelona run roughly $66–$96/hr. 2K–5K seniors; often platform-locked (UiPath / Automation Anywhere). 4–6 week senior hiring loop. Operating timezone: CET/CEST (UTC+1/+2).
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 Barcelona senior payment gateway integration talent comes from: Barcelona senior talent flows from Glovo HQ, Wallapop, eDreams ODIGEO, Telefónica Barcelona, plus UPC + UPF + UB CS programs. Mobile + travel-tech + e-commerce depth. MWC (Mobile World Congress) annual hosting effect. 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 Barcelona's Mobile & Telecom and Travel Tech 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 Barcelona, 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.
