Beschreibung

• 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. • 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.

🎯 Anforderungen

• TypeScript Proficiency: Highly proficient in TypeScript across both frontend (React/Next.js) and backend (Node.js/NestJS) environments. • Frontend Expertise: Strong experience with React and Next.js (App Router): Server Components, route handlers, streaming, metadata, i18n, and modern data-fetching patterns (SWR or equivalent). • Backend Expertise: Solid experience building production REST APIs with NestJS (or comparable Node frameworks like Express/Fastify): modules, DI, guards, interceptors, DTO validation. • Database Skills: Experience with PostgreSQL and an ORM such as Prisma. Comfortable writing and reviewing migrations, reasoning about transactions, and designing schemas that evolve safely. • API Integration Depth: Real experience integrating third-party SDKs: handling webhooks, idempotency, retries, and asynchronous fulfillment. • Problem-Solving Mindset: Collaborative, pragmatic, willing to challenge assumptions and surface tradeoffs before writing code. • Passion for AI and High Agency: Genuine enthusiasm for AI products, and a desire to bring new techniques and tools into the team proactively. • Creativity and Proactivity: You enjoy proposing features, finding creative solutions, and improving the user experience without being told to. A serious self-learner who adapts to new tools and platforms in days, not weeks. • Nice to Have: Prior experience working on payment/subscription systems. Familiarity with monorepo tooling (pnpm workspaces, Turborepo, Nx). Experience with BigQuery and event-pipeline analytics. Familiarity with Tailwind and component-driven design systems. Knowledge of cloud platforms such as Google Cloud Platform (GCP). Experience with feature-flag systems. Previous work on AI products or LLM-powered applications.
