The current team is composed of data engineers, data scientists and product managers who are spread across several geographies. The team covers a variety of industries, functions, analytics methodologies and platforms – e.g. Cloud data engineering, advanced statistics, machine learning, predictive analytics, MLOps and generative AI.
Your Impact
You will collaborate closely with a team comprising data scientists, data engineers, product developers, and analytics-focused consultants.
You will work on topics such as descriptive analytics, predictive models (e.g., boosted trees), and large language models (LLMs), particularly for segmentation use cases. Additionally, you will design and deliver products that adhere to MLOps best practices, ensuring they are both maintainable and deployable. By doing so, you will help bring advanced analytics capabilities into one of McKinsey’s flagship products, named "Wave". Your work will be the backbone for how McKinsey runs future Transformations, leveraging data science assets, to improve the odds of success for our clients.

Advanced insight generation transforming complex business questions into statically relevant analyses and these analyses into easy to digest insights. Delivering this through well documented and tested pipelines, that allow easy collaboration with other team members.
Upholding technical excellence Together with the tech lead(s) define how to build, maintain and scale our pipelines. Often piloting new technical approaches & automation. Using your business understanding to critically review model results, trends, analyses and classifications.
Coach & help other colleagues Coach & help you peers when needed, we deliver as a team.
Machine learning model development Lead the design and refinement of statistical models, optimization techniques, advanced machine learning, and predictive models
LLM optimization and evaluation Fine-tune and evaluating the performance and efficiency of Large Language Models, leveraging the latest advancements in neural network architectures and machine learning techniques
Your role might also include, as the secondary focus
Design & build creative approaches to further optimize accuracy & reduce cost In addition to optimizing the LLM through prompts and settings, you will design and test alternative approaches, such as pre-filters and non-LLM-based text models, within parallel multi-agent setups.
Build for scale Together with the tech lead(s), you will define how to maintain and scale our LLM classifier pipeline. The classifier pipeline will, in the long term, run as a on-demand batch process, and will, once stable, be refactored with scalability in mind.
