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.

Overview

We are hiring for Staff Frontend Engineer (Payments Checkout) to own and shape one of the most important surfaces at Breeze: the moment a customer actually pays.

You’ll lead the frontend architecture and evolution of our checkout experience, building payment flows that need to be fast, seamless, resilient, and built to convert. Your work will have a direct impact on customer experience and revenue, from reducing friction and improving performance to designing elegant experiences around complex payment states.

This is a high-ownership role where frontend engineering meets product and growth. You’ll work closely with Product, Design, Growth, and Payments to dig into funnel data, experiment quickly, and turn insights into experiences that make paying through Breeze feel effortless.

At the Staff level, you’ll also help set the technical direction for frontend engineering, raise the bar for architecture and performance, and mentor engineers as we scale.

If you love obsessing over the details of great checkout experiences and want to build the payment experience that powers the next generation of commerce, we’d love to meet you.

What You’ll Do

• Checkout ownership - Own the end-to-end frontend architecture for our checkout and payment flows across web platforms
• Conversion optimization - Improve checkout conversion rates through UX improvements, performance tuning, and data-driven experimentation
• Experimentation - Partner with product and growth to run A/B tests, analyze funnel performance, and ship iterative improvements quickly
• Payment UX - Build seamless flows for complex payment states including retries, failures, and authentication (3DS, etc.)
• Performance - Optimize frontend performance (Core Web Vitals, latency, rendering) to ensure fast and reliable checkout experiences
• Integration - Collaborate with backend and payments teams to integrate APIs, PSPs, and orchestration layers
• Resilience - Build robust UI systems that gracefully handle edge cases and ensure high reliability during transactions
• Frontend standards - Define and drive best practices for frontend architecture, scalability, and maintainability
• Mentorship - Act as a technical leader and mentor, raising the bar across the frontend team
• Culture carrier - Bring strong product thinking and a conversion-focused mindset into engineering decisions

What We’re Looking For

• Bachelor’s degree or equivalent practical experience
• 7+ years of frontend engineering experience building high-impact, user-facing products, ideally in fast-paced or startup environments
• Deep hands-on experience building and optimizing checkout or payment flows
• Strong proficiency with modern frontend frameworks such as React and Next.js, with a strong understanding of performance optimization and scalable UI architecture
• Experience using experimentation, analytics, and UX iteration to improve conversion and customer experience
• Strong product intuition with the ability to turn data and customer behavior into meaningful product improvements
• Familiarity with payments infrastructure such as Stripe, Adyen, Braintree, tokenization, 3DS, or similar technologies
• Strong collaborator and communicator who works effectively across Product, Design, Growth, and Engineering
• Experience with global payments, multi-currency flows, or crypto is a plus
