About the role

Key responsibilities & impact

Own and evolve OrderYOYO's payments capabilities — enabling KYC onboarding, deductions, settlement/payout timing, dispute flows, and merchant invoicing — while raising the bar on reliability, security, and engineering quality in one of our most business-critical domains.
Design, build, and operate payment-domain services, including gateway integrations and payment intent/authorisation/capture/refund flows, payout orchestration, and 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, and audit trails — that are fully supportable for finance and compliance.
Integrate with PSP and partner tooling, with close attention to tri-party / sub-merchant implications where applicable.
Implement dispute/chargeback and fraud-handling touchpoints across internal workflows and PSP tooling, and collaborate with Ops on runbooks and escalation paths.
Partner closely with Product, Legal/Compliance, Finance, and Support to convert requirements into safe, testable production behaviour.
Raise engineering quality in a high-change domain through automated testing, safe rollouts/canaries, observability, and incident-response improvements — and mentor engineers, lead design reviews, and contribute to shared standards and documentation.

Requirements

What you’ll need

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