Descripción de la vacante

Ruby Labs seeks a disciplined Middle Next.js Developer to build features for our D2C subscription products. You will own end-to-end delivery in a TypeScript monorepo—Next.js App Router client, a Fastify + Payload CMS API on PostgreSQL, and Cloudflare Workers at the edge—from task receipt to production release.

You operate with autonomy within a strict Feature-Sliced Design. Expect thorough testing, code reviews, and proactive risk communication.

Formación

• 2+ years of commercial React experience, including 1+ year with Next.js (App Router, Server Components, route handlers, rendering and caching strategies) and solid TypeScript.
• Node.js backend experience on a typed HTTP framework (Fastify, Nest, or Express) with PostgreSQL — REST API design, schema migrations, integrations over REST and webhooks — plus a working understanding of HTTP/REST, auth mechanisms, and web security fundamentals.
• Hands-on with the modern client stack: TanStack Query, Zustand, React Hook Form + Zod, Tailwind CSS, and a React component library such as HeroUI, MUI, or shadcn/ui.
• Experience with a code-first headless CMS on PostgreSQL (Payload, Strapi, Directus, or equivalent) — collections, access control, generated types, migrations.
• Testing and delivery discipline: e2e tests (Cypress or Playwright) and unit/integration tests (Vitest or Jest), Git flow, code review, working with CI.
• Daily use of AI development tools (Claude Code or equivalents), including configuring them for a project — context, instructions, rules, MCP/integrations — with full ownership of the quality, security, and correctness of generated code.
• English — B1+

Responsabilidades

• Build features across the Next.js client and the Fastify + Payload CMS backend according to product requirements
• Write code that follows the team's Feature-Sliced Design layering, naming, and import conventions
• Ship changes behind feature flags and A/B experiments, fully localized across every supported locale
• Integrate third-party providers — billing, email/CRM, analytics — over REST APIs and webhooks
• Cover functionality with unit, integration, and e2e tests at the level the team expects
• Run a thorough self-review before code review, and review teammates' code with the same rigour
• Fix bugs and perform root-cause analysis for recurring issues
• Optimize page and endpoint performance — rendering and caching strategy, database queries, bundle size
• Apply secure development practices: schema validation, access control, safe handling of secrets
• Follow observability practices — structured logging, metrics, and alerts — using existing tooling
• Break down, estimate, and ship your own tasks to production within the sprint
• Own the areas of the product you work in: their stability, performance, and follow-up fixes
• Surface requirement clarifications, estimate changes, and risks early and in writing
• Escalate complex architectural decisions and critical risks to senior engineers
