About The Position

Financial institutions process billions of transactions every day across cards, ACH, wires, and third party aggregators. But most of that data is difficult to use. Descriptions are inconsistent, merchant names don’t match, and categories vary by payment type. Spade’s API takes these raw, messy transactions, and in <50 ms, returns clean, structured records linked to verified businesses in our proprietary database. Building on that foundation, our agent layer leverages this enriched data to automate insights and decision-making. Customers including Stripe, FIS, Bilt, Corpay, and Mercury use Spade to authorize more transactions, personalize experiences, power rewards programs, and more. We lead the market in merchant coverage, speed of enrichment, and data accuracy, enriching hundreds of billions of dollars in transaction volume every month. Spade is a fast growing, Series A company backed by industry experts and top tier investors (including a16z, Flourish Ventures, Y-Combinator, and Gradient Ventures). We’re a lean and execution-oriented hybrid team, passionate about building exceptional products for our growing customer base. We care deeply about diversity of background, experience, and opinion. We value empathy, curiosity, and passion, and strive to create an environment where individuals have autonomy and the ability to take ownership over their work. What will you do? Spade is looking for a full stack engineer who thrives at the intersection of data infrastructure and developer experience. You'll join a lean, high-ownership team building real-time transaction enrichment for some of fintech's most innovative companies, and have a meaningful impact on both the product and engineering culture from day one.
