Staff Frontend Software Engineer - Payments and Checkout

At Breeze, we're building the AI-powered infrastructure layer for global commerce, making it radically simpler for businesses to sell, get paid, and operate across markets.

We go far beyond traditional payment processing. Breeze combines global payments, AI, stablecoins, and a Merchant of Record-like model to take on the complexity businesses typically manage themselves, including compliance, risk, fraud, chargebacks, reconciliation, and customer support.

Our goal is simple: let businesses focus on building and selling great products while Breeze handles the complexity behind getting paid.

Backed by Sequoia Capital, Multicoin Capital, and The Chainsmokers, Breeze is a successful, rapidly growing, and exceptionally well-capitalized company. We have the runway to think long term while remaining early enough that every person joining today can have a meaningful impact on what we build.
