About the Role

We are seeking a Deep Learning Architect with 3–4 years of experience to help design and build production-grade GenAI systems. In this role, you will contribute architecture coverage across the team—reviewing system designs, identifying gaps, and guiding technical decisions at the solution level. You will work on end-to-end LLM system design, Retrieval-Augmented Generation (RAG) pipelines, and multi-agent architectures, with a strong focus on production readiness. Robust coding depth is non-negotiable.





Responsibilities

Design and contribute to end-to-end LLM system architecture for real-world enterprise use cases (from requirements to production).
Pre-train, fine-tune LLMs and domain-specific models using techniques such as CPT, SFT, LoRA, and QLoRA for client-specific use cases.
Design and run model evaluation pipelines to benchmark performance, accuracy, and cost across different fine-tuning approaches.
Optimise models for latency, throughput, token efficiency, and inference cost in production environments.
Work alongside agent orchestration and architecture teams to integrate fine-tuned models into multi-agent pipelines.
Implement prompt versioning, rollback strategies, and model monitoring to ensure reliability post-deployment.
Translate business requirements from client engagements into model adaptation strategies with clear success criteria.
