Qu POS est une entreprise technologique qui fournit une plateforme de commerce unifiée pour les chaînes de restaurants à service rapide et décontracté. Leur plateforme intègre des systèmes de point de vente (POS), des commandes en ligne, des bornes de commande au volant et des connexions avec des places de marché tierces pour créer des expériences de commande fluides sur place et à emporter. Cela permet aux opérateurs de restaurants de gérer efficacement les écosystèmes multi-canaux et de menus, améliorant ainsi la fidélité à la marque et la précision opérationnelle. En exploitant des analyses de données riches, Qu POS vise à révolutionner le commerce des restaurants en faisant passer leurs opérations à l'ère numérique, en mettant l'accent sur la scalabilité et la croissance.

Description

• Work on building the leading enterprise restaurant technology platform (POS, kiosks, digital ordering) • Own both sides of our payments story: building the integrations that process transactions, and building the data platform that makes those transactions visible and reconciled for our merchants • Build and maintain payment integrations with PSPs across card-present (EMV terminal) and card-not-present (hosted/online) channels • Own terminal-to-cloud payment flows: device initialization, transaction processing, Store & Forward, and webhook-based reconciliation • Serve as a subject matter expert across the full payment stack, from terminal hardware through gateway to settlement • Build the reconciliation platform (UI and back-end) that matches POS transactions against PSP settlement/payout records and surfaces discrepancies • Design matching engines and data pipelines that ingest settlement files, normalize records, and classify exceptions • Create payment analytics dashboards and reports for merchant back-office users • Translate business requirements into working solutions; mentor engineers; maintain documentation and runbooks • Participate in code reviews and drive code quality across payment services

🎯 Exigences

• 7+ years in software development with meaningful payments or financial data exposure • 5+ years in C# / .NET building APIs and microservices • Hands-on PSP integration experience: gateway APIs, terminal APIs, management APIs, webhook notifications • EMV terminal integration: device pairing, transaction flows, certification, in-store troubleshooting • Fluency in payment domain concepts: acquirers, issuers, settlement (gross/net), chargebacks, PCI DSS, tokenization, PAR, authorization vs. capture, Store & Forward • Experience building data reporting UIs (Vue.js, Angular, or React) that present financial data to non-technical users • Experience with data reconciliation logic: cross-system matching, discrepancy identification, exception classification • AWS services: ECS, SQS, DynamoDB, RDS, CloudWatch, Parameter Store • MongoDB and SQL databases • Elasticsearch or similar for transaction data querying • Git, Azure DevOps Pipelines, Docker, Terraform

🏖️ Avantages
