Full Stack Engineer

Job description

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. We are looking for a full-stack engineer to help us build Terminal Web, the primary application node operators use to manage liquidity, channels, balances, swaps, and the rest of their Lightning operations. Location: Fully remote, with a preference for US time zones. THE ROLE This is a product engineering role centered on Terminal Web. You will take features from idea to production: understanding what node operators need, designing the user flow, integrating with Lightning services, building the frontend, shaping the API layer, writing tests, and sweating the details until the feature is ready to ship. You are the person we point at a product problem and trust to come back with something that works. Terminal Web is a TypeScript application built with Next.js, React, MobX, and Emotion. It uses server-side rendering, browser persistence, LNC-based RPCs to self-hosted litd nodes, and REST APIs to Lightning Labs services. The work spans UI, state management, API integration, data modeling, performance, reliability, and testing. The ideal candidate is comfortable moving across that stack without waiting for a narrow handoff. We use AI-native development tools heavily. Experience using Claude Code, Codex, Cursor, or similar tools as part of your daily engineering workflow is something we are looking for directly, not a nice-to-have. WHAT YOU'LL DO 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. You will translate protocol and API capabilities into clear product experiences. 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. Understand company priorities, identify where you can have the most impact, collaborate with product and engineering when needed, and execute from rough problem statements through launch. Use AI development tools as leverage for exploration, implementation, testing, refactoring, and documentation while maintaining the engineering judgment needed to ship secure, reliable software. WHAT WE'RE LOOKING FOR - You build and ship production-quality software. You have a portfolio, work history, or set of projects that demonstrate this, we'd love to see them. - 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, not as a novelty. - You can take ambiguous product requirements and turn them into working software independently, while communicating clearly along the way. - You have strong engineering practices: automated testing, code review, documentation, debugging, and a bias toward simple, maintainable designs. - You care about product quality. You do not just wire up APIs, you think about the user, the edge cases, the loading states, and the failure modes. - You are excited about Bitcoin, Lightning, and the mission of making Bitcoin cheap, fast, and simple for everyone. NICE TO HAVE - 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.

A strong portfolio speaks louder than a keyword-optimized resume.
