We are looking for a Full Stack Developer with a strong foundation in modern web development and hands-on experience integrating Large Language Models (LLMs) and AI workflows into production web applications.

• Build End-to-End Applications: Design, build, and maintain features across the entire stack, from reactive user interfaces to scalable backend microservices.
• Integrate AI Capabilities: Connect web backends with AI models, external APIs, vector databases, and real-time streaming services to power intelligent product features.
• Craft Real-Time Interfaces: Build rich, responsive UI components that support real-time data streaming (Server-Sent Events / WebSockets) and low-latency interactions.
• Optimize Performance & Reliability: Manage database schemas, caching, state management, and backend logic to keep the application fast, secure, and resilient.
• Collaborate & Deploy: Write clean, modular code with automated testing, CI/CD pipelines, and cloud infrastructure deployments.

• Strong proficiency in modern React frameworks (React, Next.js, or Vue.js) using TypeScript, HTML5, and modern CSS/Tailwind.
• Solid experience with Node.js/TypeScript (Next.js API routes, Express, Fastify) or Python (FastAPI, Django, Flask) or Java (Spring Boot)
• Practical experience integrating AI/LLM APIs (OpenAI, Anthropic, open-source models, or hosting services) into web applications.
• Hands-on knowledge of tools and frameworks like LangChain, LlamaIndex, or Vercel AI SDK.
• Familiarity with vector databases (e.g., Pinecone, Qdrant, pgvector) and Retrieval-Augmented Generation (RAG) concepts.
• Basic DevOps/Cloud knowledge: Docker, CI/CD, and hosting on platforms like Vercel, AWS, or GCP.
• Personal side projects or open-source contributions showcasing full-stack web applications with integrated AI/LLM features.
• Experience with web accessibility, UI design systems, or client-side performance optimization.
• Exposure to AI evaluation tools or LLM observability frameworks (e.g., Langfuse, Helicone).

• Challenging and rewarding work with real impact
• Direct Access to Cutting-Edge AI Platforms
• Diverse and Inclusive Culture
• Growth opportunities for personal and professional development
• A collaborative and innovative work environment where your ideas are valued
• Exposure to exciting projects and high-profile clients
