OVERVIEW

The Commerce Services team is responsible for payments processing, order lifecycle management, fraud prevention, and financial products that make it easier, safer, and more affordable for our customers to shop from their favorite local grocery stores. For this role, we are looking to hire strong engineers to grow our order management, payment processing, and fraud prevention teams. Millions of orders flow through our marketplace weekly. The services you design, implement, and deploy will process tens of millions of dollars in transactions daily.

Why do we need you?

We are investing heavily in the next-generation of our services. At our velocity and volume-level we need the ability to deploy new products and features faster and better. That's our choice for the traditional 3-dimensional engineering trade-off decision. We need our transactions to work perfectly; always. We can't afford to spend time looking backward at legacy limitations in our systems. We need new architectural designs and new services that couple best-in-class engineering with highly-informed business knowledge!

Do you have exceptional experience with, aptitude for, or just interest in the following software engineering areas?
  • Payment Handling and Processor Integration (e.g. Stripe, ApplePay, GooglePay, PayPal, ...)
  • Invoicing Tax Engine Integration: item taxes, service taxes, tax adjustments, and reporting
  • Invoice Discounting: first-party and third-party coupons; retention, growth, marketing discounts; ...
  • Fraud-Prevention Services: protecting our customer orders, payments, and accounts
  • Core Order Lifecycle Engine: service-oriented design providing client and service-to-service integrations, synchronous and async integrations, guaranteed transactional integrity, strong auditibility, and extreme scalability
