plasma - Senior Frontend Payments Engineer
Requirements
• You are a senior, hands-on frontend engineer with strong experience shipping React and/or React Native applications in production. • You write excellent TypeScript and care about clean, maintainable systems. • You have strong instincts around state management, data flow, performance, and user experience. • You can reason about complex systems and make them understandable through product and UI. • You are comfortable working near the backend and contributing to API and system design when needed. • You care deeply about design craft and have strong instincts around state management, data flow, performance, and user experience. • You can own features end to end, from architecture and implementation to release and iteration. • You are calm in ambiguity, direct in communication, and thoughtful about tradeoffs. • Experience building consumer fintech, payments, banking, crypto, or other high-trust products. • Familiarity with money movement, cards, KYC, fraud, compliance, ledgers, or transaction history. • Interest in stablecoins, crypto, or financial infrastructure. • Experience working close to launch or scaling an early-stage consumer product. • Plasma is built for people who want to do the hardest and most meaningful work of their career. • We hire people who are relentless about their craft and expect the same standard from everyone around them. We value ownership, urgency, clarity, and taste. We debate directly, move quickly, and care deeply about the details that make a product feel exceptional. • Engineers here are expected to understand the product, challenge assumptions, and contribute beyond their lane. You will have room to shape the product, the architecture, and the way we build.
Responsibilities
• Build and own core product surfaces using React and React Native, powering critical flows like onboarding, balances, sending, and receiving money. • Design frontend architecture that scales across platforms while maintaining consistency, performance, and reliability. • Own complex client-side state, async workflows, and error handling for real-world financial interactions. • Work full-stack where needed, collaborating closely with backend engineers and contributing to APIs and system design. • Partner deeply with design to translate intent into precise, production-quality experiences. • Anticipate and design for edge cases: latency, partial failures, retries, and degraded states. • Set standards for frontend quality, testing, performance, and maintainability. • Help make a stablecoin-powered product feel boring in the best way: fast, clear, and dependable.
