Design, build, and maintain payment integrations and a reconciliation data platform for high-volume restaurant transactions. Implement terminal-to-cloud flows, ingestion pipelines, matching engines, reporting UIs, and payment analytics. Provide technical leadership, documentation, and mentor teammates to ensure reliable settlement and reconciliation.
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.
