I’m expanding our LLM-focused R&D pod in Noida and need a hands-on Python engineer who can start contributing on day one. You must be comfortable building asynchronous back-ends in FastAPI, have real production experience creating LangChain chains and agents, and be equally at ease working with both OpenAI and Hugging Face models. Day-to-day you’ll design and optimise micro-services that call LLMs, manage embeddings in Pinecone or FAISS, and orchestrate data flows through PostgreSQL, MongoDB and Redis—everything neatly containerised in Docker for local and cloud runs. Expect plenty of room to prototype new AI features, run quick experiments, and then harden the successful ones for scale. The role is 100 % onsite in our Sector-62 Noida office; close collaboration with product and design teams is essential, so remote or hybrid isn’t an option right now. Key deliverables: • Clean, well-tested FastAPI endpoints for new AI features • LangChain agent scripts wired into vector stores and external tools • Dockerised services with CI hooks ready for staging • Documentation and hand-off notes for each sprint You’ll work directly with me and the founding engineering team, commit to two-week sprints, and demo progress every Friday. If you thrive in quick iteration cycles and love shipping AI that users touch immediately, let’s talk.

Noticed you're building async LLM microservices, most candidates gloss over the embeddings pipeline optimization piece, but that's where latency actually kills production systems. I've shipped FastAPI backends that handle LangChain agent orchestration with Pinecone at scale, built custom monitoring for OpenAI/HF model switching, and containerized the entire stack for cloud deployments. One question: are you planning to run inference locally or route everything through APIs, since that changes how we'd structure the caching layer? Can start immediately, and happy to pair on the architecture first. I'm available for on-site work as I live in Delhi.

I see you’re looking for a hands-on Python AI/ML developer to join your LLM-focused R&D pod onsite in Noida, ready to contribute from day one with FastAPI and LangChain expertise. Your emphasis on building asynchronous back-ends and working closely with the founding team really stands out. Your need for designing micro-services calling LLMs, managing embeddings with Pinecone or FAISS, and orchestrating data flows across PostgreSQL, MongoDB, and Redis while containerizing everything with Docker matches a complex but exciting challenge. I also understand the importance of quick prototyping, followed by scaling proven AI features, and the strict onsite collaboration requirement. I recently built a FastAPI-based microservice architecture integrating LangChain agents with vector stores like FAISS, managing embeddings, and orchestrating data pipelines using PostgreSQL and Redis. This included Docker containerization with CI/CD pipelines for staging deployments. My work also involved direct integration with OpenAI and Hugging Face models, delivering clean, tested endpoints and thorough documentation for hand-offs. I can deliver the first sprint’s clean FastAPI endpoints and LangChain agent scripts within two weeks, aligning with your sprint schedule and demo expectations. Let’s discuss how I can help accelerate your AI feature rollout onsite in Noida.

Hello, This role matches my day-to-day work closely. I build production FastAPI services around LLMs, LangChain agents, vector databases (Pinecone/FAISS), and containerised deployments using Docker, with OpenAI and Hugging Face models in active use. I’m comfortable owning features end-to-end — from prototype to hardened micro-service with proper testing, logging, and documentation. I’ve designed async backends that orchestrate PostgreSQL, MongoDB, and Redis pipelines, manage embeddings at scale, and expose clean APIs for product teams. Rapid experimentation followed by production-grade refinement is exactly how I prefer to work, so two-week sprint cycles and demo-driven progress fit me well. Regarding engagement: for full-time onsite work in Noida Sector-62, my monthly fee is ₹1.5 lakh. For remote/online collaboration with the same output quality and availability, my fee is ₹70k per month. I can start immediately and ramp up from day one. If you’re looking for someone who can contribute without hand-holding and ship reliable AI features quickly, I’d be glad to discuss next steps.

Hello, Your LLM R&D role immediately caught my attention because it aligns closely with the kind of systems I enjoy building—AI-powered microservices that move quickly from prototype to production. I am a Computer Science graduate with strong experience in Python backend development and AI application engineering. I have built several systems involving LLM integrations, RAG pipelines, and AI-powered developer tools, which required designing scalable APIs, embedding pipelines, and intelligent retrieval systems. I am comfortable working in fast iteration environments, experimenting with AI features, and refining them into production-ready services. I also follow clean development practices including Git-based workflows, documentation, and modular service design. The opportunity to work closely with the founding engineering team and contribute to an LLM-focused R&D environment is particularly exciting to me, especially where new AI features are rapidly prototyped and shipped to real users. I would be happy to discuss how I can contribute to building scalable AI services and LangChain-based workflows for your platform. I am able to relocate to noida for this work, i have few questions regarding time period of the completion of the project and working hours, etc. Best regards, Virendra

Saw you need someone comfortable shipping async FastAPI services that actually talk to LLMs in prod—most applicants list the tech stack but haven't debugged a stuck LangChain agent under load. Built a multi-model inference layer last quarter handling OpenAI fallbacks to open-source models, with Pinecone retrieval and Redis caching for latency. When you say "day one," are you looking for someone to jump into an existing codebase or architect the microservices layer from scratch. Let me know what makes sense and we can sync on specifics.
