AIFullStackDeveloper

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. * 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. * Collaborate on application deployment and help maintain our cloud infrastructure. **Requirements** We are
