About the Role
We’re looking for a highly experienced Senior AI Engineer based in India to join our growing global team. This role is focused on designing, developing, and deploying scalable Generative AI (GenAI) solutions for our enterprise clients. You’ll work closely with cross-functional teams across the UK, EU, and APAC regions to drive innovation in AI/ML and contribute to high-impact engagements across industries. This is a hands-on leadership role that combines deep technical work with consultancy, solution design, and AI strategy.

What You’ll Do

• Architect and develop scalable GenAI pipelines, APIs, and microservices for both real-time and batch AI applications using frameworks such as FastAPI, Ray, and LangServe.
• Design robust prompt strategies for instruction-following, reasoning, and multi-turn conversations, with a strong focus on Retrieval-Augmented Generation (RAG) architectures.
• Lead embedding model selection and fine-tuning to optimise semantic search and domain-specific GenAI solutions.
• Oversee LLM Ops workflows including orchestration, deployment, rollback, evaluation, and monitoring.
• Drive fine-tuning efforts on large language models (LLMs) to tailor outputs for regulated and industry-specific contexts.
• Establish AI testing and evaluation frameworks (including hallucination detection, safety filters, regression tests, and output quality).
• Implement observability, lineage tracking, and CI/CD automation using MLOps tools like MLflow, Databricks, Azure ML, or Vertex AI.
• Lead continuous improvement based on telemetry, user feedback, and cost-performance trade-offs.
• Actively support pre-sales engagements and client solutioning with a consultative, business-outcome-first mindset.

What You’ll Need

• 5+ years of experience in AI/ML engineering, including 2+ years focused on Generative AI and LLMs.
• Hands-on expertise in Python, cloud platforms (Azure, AWS, or GCP), and GenAI frameworks.
• Deep understanding of vector search, RAG pipelines, embedding models, and model fine-tuning.
• Familiarity with MLOps practices and tools (MLflow, Airflow, Databricks, Azure ML, etc.).
• Experience in enterprise-grade solutioning and deploying LLMs in production environments.
• Strong leadership skills with experience guiding cross-functional technical teams.
• Excellent communication and stakeholder engagement skills in a client-facing environment.
• Bachelor’s or Master’s degree in Computer Science, Data Science, Engineering, or a related field.
