Job Description

L.E.K. Consulting is seeking a Data Scientist to join its DDA (Data, Digital, and AI) practice within the Data Science & Engineering team. In this hybrid role based in Boston, MA, you will help deliver end-to-end analytics and machine learning, including LLM-based solutions, across client engagements and L.E.K.’s proprietary IP.

What you’ll do

Take data science work from conceptualization through deployment, including deploying advanced machine learning models in clients’ cloud environments with a focus on scalability, performance, and reliability.
Assist clients in using technical models effectively by supporting interpretation of results and integrating insights into their day-to-day business workflows.
Work on a broad set of complex analytical challenges, sometimes balancing multiple client engagements at once.
Deliver across the analytical stack: data aggregation and creation, cleaning and manipulation, commercial data science (including geospatial, machine learning, predictive modeling, NLP, and LLMs), and visualization.
Guide stakeholders through the interpretation of analytical outputs and the integration of data-driven insights.
Support Managing Directors with developing and scoping client proposals where data science, ML, and AI capabilities are central to delivery.
Act as a technical interface between the Data Science & Engineering team, consulting partners, and clients, ensuring alignment on fit, feasibility, and delivery expectations.
Translate technical requirements, outputs, and constraints into clear, actionable language for client-facing presentations and proposals.
Contribute to the design and commercialization of new offerings spanning data science, ML, agentic AI, and LLM-powered analytics.
Help build state-of-the-art analytical apps using up-to-date machine learning approaches to solve complex problems.
Collaborate with a range of stakeholders to continuously improve apps, service lines, and proprietary data assets.
Provide technical expertise and thought leadership on analytical tools, services lines, and proprietary data assets, and help develop these areas when applicable.
Uphold best-in-class standards in app development, software and data integrity, ensuring solutions are scalable and maintainable.
Support commercialization efforts and the upskilling of staff on relevant software, tools, and techniques.

What you’ll bring

At least 2 years of experience in applied data science with a solid foundation in machine learning, statistical modeling, and analysis.
Strong knowledge and fluency across tools such as Python (data science and ML libraries including scikit-learn, TensorFlow, PyTorch), Spark, and SQL.
Technical understanding of machine learning algorithms, including performing data science techniques such as classification models, clustering analysis, time-series modeling, and NLP. Optimization knowledge is a plus.
Experience developing and deploying machine learning models in one of: AWS, Azure, or GCP, with an understanding of cloud services, architecture, and scalable solutions (examples include Sagemaker, Azure ML, Kubernetes, Airflow).

Exposure to designing, developing, and deploying agentic AI systems (such as multi-agent orchestration or automation workflows) using frameworks such as LangChain.
Hands-on experience working with structured and unstructured datasets, including extracting and manipulating information, and comfort with best practices for data acquisition and warehousing.
Proficiency in Excel and PowerPoint, along with excellent written and oral communication skills.
Ability to understand and articulate requirements for both technical and non-technical audiences, collaborating across data science, engineering, and consulting teams.
Commercial business analytics and strategic consulting experience is preferred, and exposure to one or more core sectors (life sciences, healthcare, consumer, industrials, TMT) is a strong plus.
Strong problem-solving skills, ability to translate business needs into technical solutions, and comfort working at pace in a fast-moving, entrepreneurial environment with a high level of ownership.
