Senior payment gateway integration engineers in Montreal run roughly $66–$96/hr. 2K–5K seniors; often platform-locked (UiPath / Automation Anywhere). 3–5 week senior hiring loop; bilingual EN/FR talent. Operating timezone: ET (UTC−5).
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 Montreal senior payment gateway integration talent comes from: Montreal senior talent flows from Ubisoft Montreal (largest game-dev studio globally), Mila (Yoshua Bengio AI institute — global tier-1 AI research), Element AI alumni (acquired by ServiceNow), Bombardier, plus McGill + Polytechnique + UdeM CS programs. 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 Montreal's AI Research and Gaming 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 Montreal, 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.
