About the role

  • Payments is too critical to be tribal knowledge.
  • Personal development is central to how we work - engineers are encouraged to grow technically, take responsibility, and help shape how our products and platforms evolve.
  • We help restaurants succeed online by providing branded websites, mobile apps, and tailored marketing solutions, giving them full control of their business.

Responsibilities

  • Design, build, and operate payment-domain services, including gateway integrations and payment intent/authorisation/capture/refund flows, payout orchestration, and reconciliation.

Requirements

  • Production experience with payment flows (auth/capture/refund, webhooks, reconciliation) and "money correctness" patterns such as idempotency keys, double-entry thinking, and auditability.
  • Comfort working in an Azure-first environment (APIs, queues/eventing, monitoring), with strong CI/CD and automated testing practices.
  • Experience with sub-merchant, marketplace, or Payfac-like operating models (KYC, underwriting, settlements, fee deductions).
  • Familiarity with dispute tooling, card scheme rules, 3DS/risk rules, or fraud platforms.

Company info

  • We create a positive, inclusive environment where people are trusted to do their best work and take ownership of what they build.
