React Software Engineer, Thunes

• React applications - you've shipped features that real users depend on
• TypeScript proficiency
• Testing discipline - experience with Vitest or Jest and React Testing Library or similar
• Component library experience - you've worked with Chakra UI, MUI, or similar design systems and can extend them without fighting them
• Linux shell proficiency - comfort navigating the file system, using common utilities, and basic scripting

Desirable

• We're looking for a frontend engineer to join a small, senior team building the payment platform that powers financial operations for virtual world publishers
• You'll own frontend work across multiple codebases — an internal admin tool, embeddable payment widgets, and publisher-hosted transaction pages — all securely handling real money, real compliance requirements, and real users
• This isn't a "build marketing pages" gig
• You'll be working with GraphQL APIs backed by Go microservices, writing code that touches invoicing, payouts, KYC verification, and fraud detection
• The work matters and the stakes are real
• Admin Tools (React, Vite, Chakra UI, Apollo Client): Internal tooling used by operations teams to manage accounts, transactions, and payment methods. Turborepo monorepo with a GraphQL BFF layer
• Payment Widgets (Next.js, React, Tailwind CSS, Server Components): Embeddable checkout, payout, and KYC flows where every millisecond of load time impacts conversion. Active rewrite with a performance-first architecture
• Publisher-Hosted Pages (Next.js, Chakra UI, SSR): Multi-tenant, themeable transaction pages served under publisher-branded domains with CNAME routing and per-publisher customization
• Ship features and fixes across multiple TypeScript/React codebases
• Write and maintain unit tests (Vitest + React Testing Library) and help with Playwright e2e tests (Python/pytest)
• Work with a GraphQL API layer that translates between the frontend and Go microservices (accounts, payments, invoicing, wallets)
• Run the full local stack via Docker Compose (makeworld) with hot-reload - no waiting for builds
• Maintain or improve test coverage
• Collaborate on a small team where you'll have real ownership and influence over frontend architecture
• Small team, big impact - you won't be pixel-pushing in a feature factory. You'll shape frontend architecture across multiple products
• Real domain complexity - payments, compliance, multi-currency, fraud detection. The problems are genuinely interesting
• Modern stack, active migration - you get to help move things forward rather than maintain a frozen codebase
• Strong engineering culture - enforced coverage thresholds, pre-commit hooks, CI gates, deployment on merge. The team cares about quality and process aerodynamics
