Senior payment gateway integration talent and rates in Real Estate
Senior payment gateway integration engineers serving real estate run roughly $120–$175/hr. Stack realities for this combination: RESO Web API + IDX vendors + DocuSign + Plaid earnest-money + CoreLogic property data — common integrations: MLS (RESO Web API), Zillow / Realtor.com data feeds, DocuSign / Dotloop e-signature. Disclosure-package generation, e-sign chase sequences, MLS resync jobs
What payment gateway integration actually requires in 2026
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.
