This is an SDE II Full Stack Developer role, but mostly backend: around 70% Python and FastAPI and 30% frontend in React or Angular. You'll build and ship real AI applications such as AI agents, LLM-based workflows, and APIs that connect AI models to web products, using SQL and NoSQL databases on the cloud, mainly Google Cloud. It's not research or prototype work. What you build goes live for enterprise clients, so you'll also own performance, security, and monitoring. You'll report to the Lead Engineer and spend some time each day guiding junior engineers. The role is fully on-site in Chennai from Day 1, with hybrid possible later based on performance. The process has 3 technical rounds (1 virtual and 2 on-site) followed by a salary discussion. The panel focuses on practical system design and real projects you've built, so be ready to explain what business problem you solved and the result it delivered. If you've built and shipped AI-powered backend systems with 4ā10 years of experience and want ownership in a fast-moving AI company, this is a strong fit.
