Senior Engineer – Payments
Role purpose
Own and evolve OrderYOYO’s payments capabilities across online and in-store (POS, Kiosk & Payment terminals), supporting the transition to a more scalable operating model, and enabling capabilities like KYC onboarding, deductions, settlement/payout timing, dispute flows, and merchant invoicing.
What We Offer
- Competitive salary
- High ownership and autonomy
- Clear progression toward Tech Lead / Staff Engineer responsibilities
- Opportunity to work on revenue-critical production systems
- Strong focus on security, reliability, and engineering best practices
- Collaborative, international engineering team
- Emphasis on learning, mentoring, and long-term growth
What We’re Looking For
- 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), and collaborate with ops on runbooks and escalation paths.
- Work closely with Product, Legal/Compliance, Finance, and Support to convert requirements into safe, testable production behaviour.
- 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 (payments is too critical to be tribal knowledge).
Must‑have experience
- 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).
Nice to Have
- Experience with sub‑merchant / marketplace / Payfac‑like operating models (KYC, underwriting, settlements, fee deductions).
- Familiarity with dispute tooling, scheme rules, 3DS/risk rules, or fraud platforms.
