Full Stack Engineer

Lightning Labs builds the infrastructure that makes Bitcoin work as a global payment network. Our protocols: the Lightning Network, Taproot Assets, and L402, are used by developers all around the world and are increasingly the rails that AI agents use to pay for services, stream value, and transact autonomously.

• Ship end-to-end features in Terminal Web that help users operate Lightning nodes, manage liquidity, monitor activity, and interact with Lightning Labs products through a polished browser-based application.
• Build across the full stack of a modern TypeScript product: Next.js SSR, React components, MobX stores and view models, Emotion styling, IndexedDB-backed data services, LNC integrations, REST APIs, and the glue code that makes complex node operations feel simple.
• Own integrations with Lightning infrastructure by working with LND, litd, Lightning Node Connect, Loop, Pool, Taproot Assets, and related services.
• Write production-quality tests with Jest and Playwright, and use those tests to move quickly without breaking the workflows node operators depend on.
• Work autonomously with minimal direction.
• Use AI development tools as leverage for exploration, implementation, testing, refactoring, and documentation.

• You build and ship production-quality software.
• You have strong TypeScript and React experience, and you are comfortable with modern full-stack web application architecture.
• You have experience with server-side rendering, API clients, browser storage, state management, and the practical tradeoffs of building complex web apps for real users.
• You use AI-native development tools such as Claude Code, Codex, Cursor, or similar as part of your normal workflow.
• You can take ambiguous product requirements and turn them into working software independently.
• You have strong engineering practices: automated testing, code review, documentation, debugging, and a bias toward simple, maintainable designs.
• You care about product quality.
• You are excited about Bitcoin, Lightning, and the mission of making Bitcoin cheap, fast, and simple for everyone.

• Experience building wallet, payments, fintech, infrastructure, or developer tooling products.
• Familiarity with Bitcoin, the Lightning Network, LND, litd, LNC, Taproot Assets, Loop, Pool, or related protocols.
• Experience working with WebAssembly-backed browser integrations.
• Experience with MobX, Emotion, Dexie, Bootstrap, visx, Jest, or Playwright.
• Go experience or comfort reading backend services and protobuf-defined APIs.
• Experience at a small, high-growth company where wearing many hats was the norm.
