Job description
At Qu you’ll find a fun, dynamic, and diverse culture that celebrates team and individual success. Our people are down to earth, trail blazin’ folks who value innovation.
While mostly virtual, we collaborate closely to produce leading-edge software solutions much needed in the restaurant industry.
At Qu you will:
Work on building the leading enterprise restaurant technology platform (POS, kiosks, digital ordering). We're looking for a Senior Software Engineer who can 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.
You’ll join a scaled agile team distributed across multiple geographies, working on cloud-based and cloud-hybrid architectures that process high-volume restaurant payments daily.
Payment Processing & Integration
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
Payment Data, Reporting & Reconciliation
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 (voids, partial refunds, abandoned checks, offline payments)
Create payment analytics dashboards and reports (PAR insights, payout exports, transaction drill-downs) for merchant back-office users
Technical Leadership
Translate business requirements into working solutions; mentor engineers; maintain documentation and runbooks
Participate in code reviews and drive code quality across payment services
What We’re Looking For:
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
Bonus:
EBT payment processing or gift card systems
Fraud detection/prevention systems
Restaurant/QSR industry experience
Mobile wallets (Apple Pay, Google Pay)
International or multi-merchant payment platforms
Terminal management and remote diagnostics
Who You Are
High ownership across both code and data. You don’t treat the reporting side as someone else’s problem.
Financially precise. You understand that off-by-one-cent errors in reconciliation have real business impact.
Comfortable bridging payment infrastructure engineering and data/reporting needs in the same sprint.
Strong communicator who can explain payment flows to both engineers and business stakeholders.
Strategic thinker who balances immediate fixes with long-term platform goals.
Intellectually curious, willing to push new approaches to payment and data problems.
