As part of AI-LAB as a Full-Stack Developer, you will be instrumental in building and scaling our AI products. You will own features end-to-end across a modern Next.js frontend and our NestJS backend services, delivering a seamless and powerful user experience. You'll be joining a team with a ship-fast mindset and a modern, carefully curated tech stack.
¿Tiene lo que se necesita para triunfar? La siguiente información debe ser leída atentamente por todos los candidatos.
-
- Develop and maintain features on our Next.js (App Router) frontend using TypeScript, SWR, Tailwind, and a component-driven design system, with full internationalization (i18n) support.
- Design, implement, and maintain RESTful APIs with NestJS (TypeScript) to manage authentication, data processing, billing, usage tracking, and orchestration of AI workflows.
- Own backend services end-to-end: from schema design and migrations to deployment and observability, and contribute to new services as the product surface grows.
- Integrate and maintain third-party SDKs and APIs that power critical product flows,
including payment processing, authentication, analytics, and messaging.
- Build AI agents and tools using the Claude SDK and Model Context Protocol (MCP): giving LLMs real-time access to data, APIs, and tools so they can take meaningful actions on behalf of users.
- Contribute to schema design with Prisma and PostgreSQL, write and review migrations, and reason carefully about data models that evolve safely over time.
- Implement and maintain feature flags, A/B experiments, and analytics events so product decisions are driven by data.
- Handle incoming webhooks and asynchronous task processing with the rigor required for payment-critical and PII-handling code paths (idempotency, retries, fault tolerance).
- Collaborate with AI product managers and AI specialists to translate complex requirements into robust, scalable features — and push back on complexity when a simpler path exists.
