YOUR IMPACTAs a Data Science Specialist, you'll collaborate in a dynamic, multi-disciplinary team of 3-6 experts, using your creativity and analytics expertise to drive client performance in areas like energy efficiency, product quality, and capacity. You'll work side-by-side with client process engineers and analytics specialists, presenting your insights directly to executive audiences.
Internally, you'll partner with our talented product engineers to develop innovative products and algorithms that address both current and future client needs. You'll play a key role in codifying best practices, amplifying our impact both inside and outside the firm, and shaping the product roadmap.
You'll be based in our Brussels office as part of McKinsey's manufacturing AI solution, OptimusAI, which sits at the intersection of three practices: Global Energy and Materials, QuantumBlack, and Operations.
Global Energy and Materials: Advises production and investor companies across chemicals & agriculture, paper & packaging, metals & mining, oil & gas, and power generation on strategic, operational, and growth issues.
QuantumBlack, AI by McKinsey: The AI arm of our firm, helping clients transform faster, innovate smarter, and anticipate the future.
Operations: Assists clients in solving complex operational challenges by developing and implementing strategies and solutions for their most critical problems-connecting boardroom strategies to shop floor operators.
At the intersection of these groups, OptimusAI is a team of ~10 expert consultants, data scientists, and engineers focused on improving processing plant productivity through data analytics. We develop real-time AI advisory systems to support decision making in plant control rooms, optimize process control systems, and unlock plant bottlenecks through data-driven process changes.
OptimusAI also supports a global community of consultants by developing an innovative machine learning toolkit and codifying our approach to deliver significant and lasting client impact.
You'll benefit from world-class training in business problem structuring and client advisory, working closely with senior manufacturing and analytics experts. Experience unparalleled career growth, with significant ownership and responsibility from day one, all within a collaborative, diverse, and non-hierarchical environment. Plus, seize the opportunity to travel to client sites-locally and around the world.
There is a flexibility to hire at different role level, depending on your experience.
