Data Scientist à United States

6-month Internship beginning in September 2025

Upflow revolutionizes the way B2B businesses get paid, unlocks owed cash reserves, and empowers B2B companies to grow better.

Most modern, fast-growing companies are fully focused on sales growth and retention and struggle to maintain focus on cash collection. This leads to thousands of unpaid invoices, broken communications, outdated payment methods, and a negative customer experience. As a result, cash flow suffers, and growth is inhibited. Upflow is the modern collections hub that manages all data, analytics, communications and payments to improve cash flows.

We are a product-led organization launched in 2018 and trusted by hundreds of companies across the US and EMEA, including Lattice, Front, Iziwork, ProductBoard, and more. We're also backed by leading investors (YCombinator, 9yards, eFounders) and top business angels from N26, Square, Mercury, Uber, and Netsuite.

We're distributed across three continents and rapidly expanding. It's a perfect time to join if you're looking for an exciting personal growth opportunity and international experience.
