# Full Stack Engineer

**Company:** [Lightning Labs](https://hotfix.jobs/companies/lightning-labs)
**Location:** Remote
**Role:** Fullstack Engineering
**Skills:** TypeScript, React, Next.js, Mobx, Emotion, Jest, Playwright, Lightning Node Connect, Lnd, Litd, Loop, Pool, Taproot Assets, Indexeddb, REST APIs
**Posted:** 2025-09-29

> Build and ship full-stack features for Terminal Web, a TypeScript app for Lightning node operators to manage liquidity, channels, and operations. Requires strong React/Next.js skills, Lightning protocol integrations, testing, and AI development tools.

## Job Description

## 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.
- 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, 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.
