## About the Role

* You have at least 2 years of software engineering experience in formal, full-time work environments
 * You've built web interfaces with React and TypeScript
 * You've written backend code, such as APIs or services, using Node and TypeScript
 * You enjoy working across the stack, from building interfaces people use to the APIs and data behind them.
 * You have a solid grasp of programming fundamentals, including HTML and CSS, data structures, APIs, databases, and writing tests, and you're eager to deepen them.
 * You display a strong sense of ownership of your work by monitoring performance, usage, and errors after it ships.
 * You're curious. You seek to understand the "why" behind things so you can better plan and build the "how."
 * You use AI tools in your work and think critically about what they produce.
 * You care about the people who use what you build. You practice empathy and thoughtfulness as you weigh trade-offs.
 * You strive for code that's readable, testable, and maintainable, and you leave things better than you found them.

Nice to have:

 * Experience with SQL databases such as Postgres.
 * Exposure to REST or GraphQL APIs, GraphQL clients like Relay or Apollo, or building against third-party APIs.
 * Familiarity with web accessibility or component-driven development.
 * Familiarity with message queues or event-driven systems.
 * Interest in payments, billing, or SaaS integrations.

## Description

We're looking for a Junior Fullstack Engineer who is building their foundation and wants to grow quickly alongside experienced teammates. You'll work in one of two engineering squads, Gateway or Connect, shipping real features across our React web app and Node backend that small businesses rely on every day. You'll have a dedicated mentor, well-scoped work, and plenty of room to learn how a world-class production SaaS platform is built, run, and scaled., * Spend most of your time writing, testing, and shipping code in TypeScript, across our React frontend and Node backend.

 * Build user-facing features in our web app, working from designs in Figma and our shared component library.
 * Own well-scoped tasks end to end: understand the customer problem behind a ticket, build and test the change, and confirm it works once it's live.
 * Investigate and fix bugs reported by customers and our support team.
 * Review your teammates' code and learn from their reviews of yours.
 * Write tests and documentation alongside your code, so the next person can pick up where you left off.
 * Use AI coding tools to move faster while maintaining personal growth.
 * Work closely with your mentor and squads, ask questions early, and grow toward owning larger pieces of work.

Technical stack and tools:

 * Our web app is built with React and TypeScript, using GraphQL and Relay for data fetching.
 * We build UI with Vite, Vanilla Extract, and React Aria, and develop components in Storybook.
 * We test with Vitest and React Testing Library.
 * Our backend is built on Node using TypeScript.
 * Our architecture is event-driven microservices with RabbitMQ at the center, with a federated GraphQL layer.
 * We use a variety of databases for different purposes: Postgres, Elasticsearch, and Redis.
 * Observability and delivery tools.
 * Other tools: Claude Code and other AI coding tools, Linear, Notion, Slack, and Figma.
