Senior Machine Learning Engineer

This role is for one of the Weekday's clients Salary range: Rs 5000000 - Rs 7000000 (ie INR 50 - 70 LPA)

Min Experience: 5+ years Location: Noida, Uttar Pradesh, India JobType: full-time

As a core engineer in a brand-new 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. Requirements 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 Required Must-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 engineers). RAG & Agent Orchestration: Deep experience building and shipping RAG or agentic systems using production-proven frameworks (e.g., LangChain, LangGraph, or custom equivalents), with strong tool-calling and multi-step reasoning design. Automated Evaluation: Track record of building scientific evaluation workflows, systematic regression testing, and quality monitoring for LLM outputs. Backend Integration: Practical experience with API development, backend data pipelines, and cloud deployment infrastructure. Good-to-Have Skills: Model Fine-Tuning: Hands-on experience with LoRA, QLoRA, SFT, or DPO preference optimization. Inference Optimization: Experience reducing latency and serving costs via quantization (AWQ/GPTQ), ONNX compilation, or serving frameworks like vLLM/TGI. Distributed Frameworks: Familiarity with DeepSpeed or FSDP for handling training datasets at scale. What We Offer Population-Scale Impact: Directly shape how millions of children across India learn and thrive within public education systems. Autonomy of a 0-to-1 Build: Enjoy the agility and growth potential of building a team and product from scratch, backed by the stability of a highly successful, profitable parent company. Comprehensive Benefits: Competitive compensation package, supportive work culture, and employee-centric health insurance benefits.
