Own and evolve OrderYOYO’s payments capabilities across online + in-store (POS, Kiosk & Payment terminals)
Design, build and operate payment-domain services (gateway integrations, payment intent/authorisation/capture/refund flows, payout orchestration, reconciliation)
Implement marketplace capabilities where relevant: onboarding/KYC integration, merchant configuration, settlement instructions, deductions, and invoicing/merchant-statement alignment
Build robust “flow-of-funds” primitives: idempotency, ledgers/events, audit trails, and supportability for finance/compliance
Integrate with PSP and partner tooling with attention to tri-party / sub-merchant implications where applicable
Implement dispute/chargeback and fraud-handling touchpoints (internal workflows + PSP tooling)
Collaborate with ops on runbooks and escalation paths
Raise engineering quality in a high-change domain: automated tests, safe rollouts/canaries, observability, and incident response improvements
Mentor engineers, lead design reviews, and contribute to shared standards and documentation

Strong backend engineering background in distributed systems (microservices, async processing, resilient APIs, eventual consistency)
Production experience with payment flows (auth/capture/refund, webhooks, reconciliation) and “money correctness” patterns (idempotency keys, double-entry thinking, auditability)
Solid security mindset: PCI, protecting PII, secrets management, least privilege, secure coding
Comfortable in an Azure-first environment (APIs, queues/eventing, monitoring), and with CI/CD + automated testing practices
Clear communication with non-technical stakeholders in high-stakes scenarios (incidents, financial breaks, compliance asks)
