Sarvam is building the bedrock of Sovereign AI for India. The company is developing India’s full-stack sovereign AI platform, building across research, models, infrastructure and applications with a singular focus on making AI genuinely work for India. Sarvam works with leading enterprises and public institutions and is backed by Lightspeed, Peak XV, and Khosla Ventures. Sarvam partners with India’s leading brands, including Tata Capital, SBI Life, CRED, IDFC, and LIC. About the Role You’ll work directly on Sarvam’s production dubbing pipeline — a Python library and FastAPI service that orchestrates translation, text-to-speech, quality control, and audio stitching across 10+ Indian languages. This is backend software engineering: reading and improving real production code, adding features, handling failures gracefully, and making complex async systems reliable and fast.   Your code will run in production, processing real dubbing jobs. The emphasis is on clean architecture, robust error handling, and making the system easy to extend as new providers and capabilities are added. What You’ll Do Read, understand, and improve existing production Python code (async pipelines, API integrations, retry logic) Add features: configurable parameters, structured logging, caching, timeout handling Improve error handling: distinguish rate limits from auth errors from server failures, add fallback logic Refactor for clarity and extensibility: provider abstractions, config objects, cleaner interfaces Write code that integrates with external APIs (Gemini, ElevenLabs, Sarvam services) with proper retry and observability What We're Looking For Strong Python fundamentals — comfortable reading and writing production-quality code (not just notebooks) Understanding of async/await and why it matters for I/O-bound services Good instincts around error handling, logging, and making systems observable Ability to read unfamiliar code quickly and trace data flow through a system Familiarity with using AI coding tools (ChatGPT, Copilot, Claude) to accelerate your work Bonus Points Experience with FastAPI, aiohttp, or similar async Python frameworks Familiarity with retry libraries (tenacity) or resilience patterns Exposure to Pydantic, dataclasses, or typed Python Experience writing tests and mocking external services Understanding of API design and provider abstraction patterns Why Sarvam? Sarvam is a fast-moving, high talent-density team building full-stack AI for India, working on problems that push the frontiers of AI with real population-scale impact. Work alongside researchers, engineers, builders, and business leaders who move fast and hold each other to a very high bar High ownership and high impact, from day one Everything we do is AI-first, from the way we build and ship to the way we think about problems You can work on problems that could change how an entire country learns, works, and communicates If you want to work on problems at the frontier of AI in India, Sarvam is the place to be.
