Min Experience: 5+ years
Location: Noida, Uttar Pradesh, India
JobType: full-time
As a core engineer in a brand-current 0-to-1 vertical build, you will design, build, and ship production-grade, LLM-powered systems tailored for personalized learning in Indian languages and local educational contexts. You will own applications end-to-end: RAG pipelines, agentic workflows, evaluation harnesses, and the production microservices that serve them.
We maintain a strict bar for robust software engineering, not just prompt crafting or notebook experimentation. This role requires high ownership, comfort with ambiguity, and hands-on execution during our early vertical setup phase.
Key Responsibilities
Production LLM Pipelines: Architect and deploy robust LLM applications (RAG architectures, multi-step agentic workflows, and tool-calling systems) for use cases like automated question answering, adaptive feedback, and curriculum alignment.
Full-Stack ML Systems: Own data pipelines,



retrieval layers, orchestration layers, APIs, and service infrastructure—written as clean, maintainable, and thoroughly tested production code.
Rigorous Evaluation Frameworks: Build task-specific benchmarks, regression testing, human-in-the-loop evaluation loops, and automated quality gates to systematically prevent model degradation.
Latency & Cost Engineering: Implement prompt optimization, caching strategies, request batching, and model routing to ensure production systems remain fast and financially viable at a population scale.
Indic Language Grounding: Build and scale data preparation pipelines for instruction data, with a specific focus on multilingual and Indic language sources.
Technical Profile RequiredMust-Have Skills:
Production-Grade Python: Strong background in writing clean, modular, and tested Python code. Experience owning live services in production is non-negotiable (no notebook-only
