About One Pay

One Pay is the consumer fintech trusted by millions of Americans to make money better.

Our financial system is broken. High fees, low rates, and too few ways to actually grow your money. We’re fixing it. And we’re moving fast.

We’re an all-in-one financial services platform that brings together banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto in one place. We also partner with employers, HCM providers, gig platforms, and others to deliver embedded financial services to millions of employees and frontline workers.

We’re backed by Walmart, the world’s largest retailer, and Ribbit Capital, one of fintech’s most respected investors, giving us rare scale, distribution, and the opportunity to build something truly category-defining.

But what really sets One Pay apart is how we move. Our customers don’t have time to wait… and neither do we. This place moves fast, and we’re looking for people who are:

• Ready to run

• Hungry and driven by urgency

• Exceptional at what they do, with low ego

• Comfortable operating in motion

Experience Design at One Pay shapes how millions of people interact with their money. The product touches saving, spending, borrowing, and growing wealth – often for people the traditional financial system has underserved. That weight raises the bar on what we ship and how we ship it.

We’re a small, senior team with roots at Apple, Meta, Ford, Airbnb, and leading fintechs – low ego, high craft, and genuinely collaborative. AI is a baseline part of how we work, not a future we’re talking about.

We’re looking for a Design Engineer to help define what modern design-to-code looks like s is a first-class engineering role with design fluency. You’ll generate production-ready components directly, use AI coding tools aggressively, and help push the team past traditional spec-based handoff. You’re not executing the current model – you’re shaping what comes next.

• You ship in code. Figma is part of how you communicate, but you’re most fluent in the codebase. You generate production-ready work, not just specs.

• You’re AI-native at production velocity. Cursor, Claude Code, v0, similar tools – they’re already how you move. You ship more in a day than most teams do in a week.

• You’re rethinking handoff. The traditional model is breaking down, and you’re excited to define what replaces it.

• You translate fluently. You speak both languages. Designers trust you, engineers trust you, and you make the gap between them disappear.

• You sweat the implementation. A two-pixel drift in production matters to you. So does a token that doesn’t quite map. You catch what others miss.

• You operate in motion. Process is fluid here, and you help shape it as you ship.

We use Node and Type Script on the server, leveraging the NestJS framework within a microservice-oriented architecture running on Kubernetes and AWS. On the client side, we build and ship product features for iOS, Android, and web platforms using React Native. We also embrace AI-assisted development, so engineers have their choice of Claude Code or Cursor to fit their workflow.
While you don't need experience with our exact stack, familiarity with modern software engineering practices will help you ramp up quickly.

• Fluency in both Figma and code (React Native or React).

• Active use of AI coding tools (Cursor, Claude Code, v0, or similar) at production velocity.

• Fluency in design tokens, component architecture, and how design systems map to code.

• Experience shipping on cross-functional teams where design and engineering overlap.

• Strong communication across both disciplines.

• A track record of operating in fluid environments and helping define how…
