Job requirements
- you have experience with JavaScript (React, Node.js, GraphQL) with Typescript,
- you're familiar with relational databases (preferably PostgreSQL) and testing frameworks like Jest, React Testing Library, Cypress
- you have designed a data model from scratch for a new feature — thought through the schema, relationships, and indexes, and evolved it with migrations as requirements changed
- you have experience building a complex, stateful interface — something with forms, validation, optimistic updates, or real-time data — not just static pages
- you know how to write meaningful tests (unit, integration, or end-to-end) that caught regressions and gave the team confidence to ship
- you're comfortable working in a scrum environment
- you're familiar with AI coding assistants as part of everyday development — for scaffolding, tests, refactors, and exploring unfamiliar code faster
- you treat AI output as a first draft, not a final answer: reviews it as carefully as a teammate's pull request, verifies correctness, and never merges code they don't fully understand
