Fetch•Reston, VA

6h•Remote

About The Position

Fetch is investing in the future of digital receipts. Today, we process tens of millions of receipts monthly through email scanning, mobile integrations, and retail partnerships, but we believe there is a much larger opportunity ahead. We are opening this role to explore a new vertical within our eReceipts platform. The focus is R&D at the intersection of open banking, Point-of-Sale systems, and consumer-permissioned financial data, finding new ways to access item-level transaction data that powers our rewards ecosystem. This is greenfield work: researching what's possible, prototyping approaches, and building the foundation for what comes next. This is a full-time role that can be held from one of our US offices or remotely in the United States.

Requirements

Domain experience in one or more of: fintech, open banking, digital receipts, card-linked offers, Point-of-Sale systems, transaction enrichment platforms
Experience building or consuming third-party APIs and partner integrations, including rate limiting, retry strategies, data contract negotiation, and multi-partner onboarding
Experience working with transaction or receipt data, including ingestion, normalization, or enrichment of purchase, order, or payment data from multiple sources
Strong understanding of OAuth 2.0 and secure credential management in a B2B or consumer-permissioned data context
Commitment to code quality through automated testing and observability
Strong communication skills and a collaborative mindset
Ability to leverage AI tools for coding, documentation, testing, and code review

Familiarity with service-oriented architecture patterns
