Senior Full-Stack Engineer (Typescript, next.js, Stripe Connect) - PT - EMEA/LATAM/NA

About the role

The product is built — UI and core screens exist. What's needed is an engineer who can take it from built to live and taking real money. This is not a front-end build; it's commercial plumbing: payment flows, payout logic, and financial correctness under real transactions in two markets.

The work

• Run the core booking-to-payment loop end to end for the first time — it hasn't been proven yet.
• Bring iDEAL live for Dutch customers (EUR) alongside card payments for UK customers (GBP), via Stripe Connect.
• Replace the hardcoded commission rate with a proper rule-based system.
• Handle the full transaction lifecycle: charge, hold, release to provider, payout, and refund — correctly, in both markets.

Definition of done

• A Dutch customer completes a real booking and pays via iDEAL in euro.
• A British customer completes a real booking and pays via card in pounds.
• Commission resolves correctly on both.
• Funds release to the provider correctly in each case.
• One real booking in each market has been taken, released, paid out, and refunded successfully.

What you'll need

• Hands-on Stripe Connect in production: multi-party flows — authorise, capture, hold, transfer, payout, refund, and dispute (rather than checkout integration)
• A redirect-based, asynchronous payment method shipped in production (iDEAL, Bancontact, Sofort, Przelewy24). Confirmation on webhook, never on redirect return.
  Note: Card payments launch first; this model lands in a second release, and the architecture must support it without reworking the booking flow.
• PostgreSQL depth: row-level security, migrations, and multi-currency logic across EUR and GBP.
• Comfortable working from an existing interface and a detailed brief, and flagging gaps or risks in scope rather than absorbing them silently.
