About The Position

Oliver Wyman Quotient partners with clients to deliver breakthrough outcomes for their toughest AI challenges by blending AI technology with deep industry expertise. We accelerate and embed AI transformation by building strong capabilities and culture, co-creating customer-focused solutions, modernizing technology, harnessing data and analytics, and building resilience for future risks and optimized operations. We work collaboratively with clients to define, design, and achieve lasting results. As a Senior Lead AI Engineer, you will manage technical projects and guide teams in designing and building production-quality, extensible AI/ML systems and pipelines. You will act as an expert in selected domains, choosing appropriate approaches based on data or modeling problems. You will collaborate with Oliver Wyman partners and clients to understand business challenges and craft solutions with other OW Quotient specialists. Responsibilities include exploring data, crafting AI solutions, shaping proposals, building and deploying LLM-based agent systems, staying current with AI/ML methodologies, advocating for best practices, and leading the development of proprietary AI/ML solutions and infrastructure.

Requirements

Technical background in computer science, data science, machine learning, artificial intelligence, statistics or other quantitative and computational science
Compelling track record of designing and deploying large-scale technical solutions, which deliver tangible, ongoing value
Direct experience having built and deployed robust, complex production systems that implement modern artificial intelligence at scale
Comfort in environments where large projects are time-boxed, and therefore consequential design decisions may need to be made and acted upon rapidly
Demonstrated fluency in modern programming languages for artificial intelligence / agents, covering the end-to-end AI development lifecycle
Knowledge of one or more agentic platforms, including but not limited to: Azure Foundry, AWS Bedrock, Gemini Enterprise Agent Platform
Deep familiarity with the architecture, performance characteristics, and limitations of compound AI systems, including retrieval-augmented generation, tool use, agentic memory, and multi-agent orchestration
Experience designing and operating evaluation frameworks and observability tooling to measure AI system quality, detect failure modes, and maintain performance in production
Proficiency in LLM system design, including prompt engineering, context and token management, structured output, fine-tuning tradeoffs, and cost/latency optimization
Practical awareness of AI risk, bias, and governance, including how to identify and mitigate failure modes in high-stakes or regulated environments
Solid theoretical grounding in the mathematical core of the major ideas in AI/ML
Applied understanding of a class of modelling or analytical techniques
Fluency in the mathematical principles and generalizations of data science – e.g., Statistics, Linear Algebra and Vector Calculus

Nice To Haves

A history of compelling side projects or contributions to the Open-Source community is valued but not required
Experience presenting at high-impact AI/ML engineering conferences and solid connections to the AI/ML community (e.g., via meetups, open-source contributions, continuing relationships with academics, etc.) is highly valued
Interest/background in Financial Services, Healthcare and Life Sciences, Consumer, Retail, Energy, or Transportation industries

Responsibilities
