Strong-to-Have Experience * 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. ## Description At OrderYOYO, payments sit at the heart of everything we do. Every order placed, every restaurant paid, and every dispute resolved runs through the systems this team owns and operates., We're looking for a Senior Software Engineer - Payments 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). 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. Role Mission 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. Core Responsibilities * 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. Payments is too critical to be tribal knowledge. ## Related Videos - [APIs and Architecture for scaling omnichannel payments](https://www.wearedevelopers.com/videos/90-apis-and-architecture-for-scaling-omnichannel-payments) - [Beyond Webhooks: The Future of Scalable API Event Delivery](https://www.wearedevelopers.com/videos/100312-beyond-webhooks-the-future-of-scalable-api-event-delivery) - [How to Cause (or Prevent) a Massive Data Breach- Secure Coding and IDOR](https://www.wearedevelopers.com/videos/39-how-to-cause-or-prevent-a-massive-data-breach-secure-coding-and-idor) - [Microservices: how to get started with Spring Boot and Kubernetes](https://www.wearedevelopers.com/videos/242-microservices-how-to-get-started-with-spring-boot-and-kubernetes) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [The Vonage Trivia Voyage: Quiz Your Way to the Top!](https://www.wearedevelopers.com/videos/761-the-vonage-trivia-voyage-quiz-your-way-to-the-top) ## Related Articles - [Highest Paying Tech Companies in Europe](https://www.wearedevelopers.com/magazine/162-highest-paying-tech-companies-in-europe) - [Software Developer Salary in The Netherlands [2023]](https://www.wearedevelopers.com/magazine/217-software-developer-salary-in-the-netherlands-2023) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
