## About the Role

Must-haves:

 + 3-5 years building production web applications, comfortable on both frontend and backend
 + Strong React and TypeScript skills - You can build complex UIs confidently
 + Backend experience with Node.js - You can write APIs, work with databases, and debug across the stack
 + Solid SQL skills - You can write queries, understand schemas, and think about data
 + Strong product intuition - You've shipped features where you made design and technical calls, not just followed tickets
 + Excellent communication - You can articulate tradeoffs clearly, push back respectfully, and work well async
 + Comfortable with ambiguity - Requirements will be fuzzy. You ask the right questions, make reasonable assumptions, and move forward without hand-holding
 + Fluent English - We're a distributed team; clear written and verbal communication is essential
Strong signals:

 + You've worked at an early-stage startup before (and liked it)
 + You have side projects or open source contributions that show you build things because you're curious
 + You've used AI coding tools and have opinions about them
 + You care about craft - clean code, good abstractions, thoughtful UI details

## Description

+ Ship features end-to-end - From database to UI. You'll work across React/TypeScript and Node.js (with some legacy Go), owning features from start to finish.
 + Make product decisions - See a confusing UX? Fix it. Have a better idea for an API design? Propose it and build it. We trust engineers to make smart calls on small-to-medium product decisions.
 + Build with AI tools - We use AI coding tools daily (Claude Code, Cursor - team members pick what works for them). You should be comfortable (or excited) to work this way.
 + Work directly with design - Implement pixel-perfect, responsive interfaces from Figma. Push back when something doesn't make sense.
 + Own your code in production - We do continuous deployment. What you merge today is live today. You'll debug, monitor, and improve what you build., + Not a laid-back 9-to-5 - Startup doesn't mean less oversight and more flexibility. It means more ownership, higher stakes, and sometimes intense pushes. We respect personal time, but when we ship, we ship hard.
 + Not highly structured - If you need detailed specs and clear roadmaps to function, this isn't the place.
 + Not single-track - If you only want to do frontend or only backend, check out our other roles. This one requires range.
