Job Summary

10+ years (min. 2 years in GenAI / LLM systems) We are seeking a Senior AI/ML Engineer to design, develop, and deploy production-grade AI/ML solutions within GSK’s Digital & Tech organization. This role focuses on building Generative AI applications, multi-agent systems, and advanced retrieval pipelines that drive measurable business impact. You will work at the intersection of cutting-edge AI research and enterprise software engineering, collaborating with data scientists, platform engineers, and domain experts across R&D, supply chain, and commercial functions.

Key Responsibilities

Generative AI & LLM Development

  • Design, develop, and deploy Generative AI applications using LLMs (GPT-4, Claude, Gemini, open-source models) for enterprise use cases
  • Build and orchestrate multi-agent systems using frameworks like LangGraph, LangChain, CrewAI, or AutoGen with function calling and tool use
  • Implement Retrieval-Augmented Generation (RAG), Graph RAG, and hybrid retrieval pipelines using vector databases (Pinecone, Weaviate, Chroma, pgvector)
  • Apply prompt engineering, chain-of-thought reasoning, and context engineering techniques to optimize model outputs
  • Fine-tune LLMs and embedding models for domain-specific tasks using LoRA, QLoRA, or full fine-tuning approaches
  • Implement guardrails, content filtering, and safety mechanisms for responsible AI deployment

ML Engineering & MLOps

  • Build end-to-end ML pipelines – data ingestion, feature engineering, model training, evaluation, and deployment
  • Implement LLMOps practices: model versioning, A/B testing, prompt management, evaluation frameworks (LLM-as-judge, RAGAS, custom metrics)
  • Deploy and manage LLM inference using frameworks such as vLLM, TensorRT-LLM, or DeepSpeed for latency and cost optimization
  • Monitor model performance, detect drift, and implement continuous improvement loops
  • Build observability for AI systems using LangSmith, Langfuse, or custom tracing solutions

Architecture & Cloud

  • Architect scalable AI solutions on AWS (Bedrock, SageMaker, Lambda) or Azure (OpenAI Service, ML Studio)
  • Containerize AI applications with Docker and deploy via Kubernetes, ECS, or serverless patterns
  • Design event-driven and API-first architectures for AI service integration with enterprise systems
  • Implement CI/CD pipelines for ML models and AI applications

Collaboration & Leadership

  • Collaborate with data scientists, domain experts, and product owners to translate business problems into AI solutions
  • Conduct code reviews, architectural design reviews, and contribute to engineering standards
  • Mentor junior AI/ML engineers; lead technical knowledge-sharing sessions
  • Evaluate and recommend emerging AI technologies, frameworks, and approaches
  • Present AI solutions and results to technical and non-technical stakeholders
