Every order placed, every restaurant paid, and every dispute resolved runs through the systems this team owns and operates.<br/><br/>We're looking for a <strong>Senior Software Engineer – Payments</strong> to help us build a more resilient, scalable, and compliant payments operating model — across online ordering and in-store platforms (POS, Kiosk, and payment terminals).<br/><br/>You'll play a central role in shaping how OrderYOYO handles money — from authorisation and settlement to disputes and merchant invoicing — across a rapidly growing, international restaurant platform.<br/><br/><strong>Role Mission<br/><br/></strong>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.<br/><br/><strong>Core Responsibilities<br/><br/></strong><ul><li> Design, build, and operate payment-domain services, including gateway integrations and payment intent/authorisation/capture/refund flows, payout orchestration, and reconciliation.</li><li> Implement marketplace capabilities where relevant: onboarding/KYC integration, merchant configuration, settlement instructions, deductions, and invoicing/merchant-statement alignment.</li><li> Build robust “flow-of-funds” primitives — idempotency, ledgers/events, and audit trails — that are fully supportable for finance and compliance.</li><li> Integrate with PSP and partner tooling, with close attention to tri-party / sub-merchant implications where applicable.</li><li> Implement dispute/chargeback and fraud-handling touchpoints across internal workflows and PSP tooling, and collaborate with Ops on runbooks and escalation paths.</li><li> Partner closely with Product, Legal/Compliance, Finance, and Support to convert requirements into safe, testable production behaviour.</li><li> 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. Payments is too critical to be tribal knowledge.<br/><br/></li></ul><strong>Must-Have Requirements<br/><br/></strong><ul><li> Strong backend engineering background in distributed systems — microservices, async processing, resilient APIs, and eventual consistency.</li><li> Production experience with payment flows (auth/capture/refund, webhooks, reconciliation) and “money correctness” patterns such as idempotency keys, double-entry thinking, and auditability.</li><li> A solid security mindset: PCI compliance, PII protection, secrets management, least privilege, and secure coding practices.</li><li> Comfort working in an Azure-first environment (APIs, queues/eventing, monitoring), with strong CI/CD and automated testing practices.</li><li> Clear, confident communication with non-technical stakeholders in high-stakes scenarios — incidents, financial breaks, and compliance requests.<br/><br/></li></ul><strong>Strong-to-Have Experience<br/><br/></strong><ul><li> Experience with sub-merchant, marketplace, or Payfac-like operating models (KYC, underwriting, settlements, fee deductions).</li><li> Familiarity with dispute tooling, card scheme rules, 3DS/risk rules, or fraud platforms.<br/><br/></li></ul><strong>Who We Are<br/><br/></strong>At OrderYOYO, company culture comes first. We create a positive, inclusive environment where people are trusted to do their best work and take ownership of what they build. 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.<br/><br/>We help restaurants succeed online by providing branded websites, mobile apps, and tailored marketing solutions, giving them full control of their business. By removing high commission fees charged by third-party platforms, we empower restaurants to grow sustainably.<br/><br/>Through our partnership with AppSmart, the market leader in POS and in-store systems, we've become the largest restaurant-focused platform in Europe.<br/><br/><strong>What We Offer<br/><br/></strong><ul><li> Competitive salary.</li><li> A remote role — work from wherever you do your best work, with quarterly in-person gatherings at one of our global offices.</li><li> High ownership and autonomy.</li><li> Clear progression toward Tech Lead / Staff Engineer responsibilities.</li><li> The opportunity to work on revenue-critical production systems.</li><li> A strong focus on security, reliability, and engineering best practices.</li><li> A collaborative, international engineering team.</li><li> Real emphasis on learning, mentoring, and long-term growth.</li></ul> </div>
