We are expert in a wide range of industries, including Life Sciences and healthcare, retail and consumer, financial services, industrials, energy and transportation.

The Associate (Data Scientist) role

As an Associate (Data Scientist) you split your time roughly 50:50 between:

Case delivery – embedded in consulting teams to solve live client questions with data science and advanced analytics; and
IP & capability build – designing, building and shipping state of the art data science modules that are reused across the entire firm

You will be a fully-fledged member of both the Consulting practice and the Data & Analytics (D&A) team, enjoying the rapid learning curve of the Associate path while deepening your specialist technical expertise. The Associate (Data Scientist) role at L.E.K. offers exposure to multiple industry sectors and a wide variety of commercial and technical challenges. The nature and pace of L.E.K.’s strategic work facilitates the rapid development of your skill set in a collaborative and rewarding team-based environment. As you progress you will take on a significant level of responsibility and build your leadership skills.

With the guidance and support of an experienced senior team, you will:

Frame business problems with case managers and client executives, translate them into analytical road-maps
Deliver end-to-end analytical work-streams: data scoping, modelling, insight generation, presentation
Build, test and document production ready ML models—from gradient boosted trees to GenAI and timeseries forecasting—packaged as internal Python packages or RESTful services.
Build interactive front-ends (Tableau, Streamlit, Plotly Dash) so non-technical users can explore results intuitively
Turn insights into actionable recommendations and present findings to clients;
Contribute reusable components (feature engineering blocks, forecasting engines, GenAI pipelines) to our internal AI/ML toolkit
Support business-development by shaping analytics in proposals and thought-leadership

Tech you’ll use (and learn)

Python
SQL
scikitlearn
XGBoost
TensorFlow/PyTorch
LangChain
Airflow
dbt
AWS/GCP/Azure
Docker
Kubernetes
Tableau
Streamlit
GitHub Actions
We’re tech agnostic and believe in using the right tool for the job—so expect to pick up new languages and frameworks quickly.

What We’re Looking For

Degree (2:1 or above) or Master’s in a quantitative field (Data Science, Computer Science, Engineering, Mathematics, Physics, Economics etc.)
0–2 yrs experience applying Python/SQL & core ML to real-world data sets
Confidence explaining technical concepts to senior business audiences
Intellectual curiosity, humility and a drive to take ownership

(Cloud, dev-ops or consulting exposure are welcome but not prerequisites)

What We Offer

Training: two-week Associate induction, monthly skills modules, pair-programming with senior data scientists, coaching from consultants, a dedicated development manager
Progression: clear pathway to the Consultant (Data Scientist) role without needing to attain an MBA
Immediate impact & ownership: your modules move to production
Best of both worlds: startup build velocity + the resources, data access and client exposure of a top-tier global consultancy.
Benefits: Competitive salary, profit share, pension, private healthcare, flexible working, tech allowance, and a vibrant social calendar.
