Summary
👤
Senior🎓
Top SchoolBen Leën is a Director of Engineering with 10+ years of experience building business-critical B2B applications, data products, and the platforms that power them, currently leading cross-functional teams at McKinsey & Company from Bonheiden, Belgium. He blends hands-on product and infrastructure knowledge—application development, cloud, data, observability, and security—to modernize platforms and accelerate delivery at scale. Ben’s leadership focuses on pragmatic architecture, automation, and establishing strong agile and product-engineering practices that enable team autonomy and measurable business impact. He has progressed through technical and managerial roles at McKinsey since 2012 after earlier development work at Cegeka, giving him deep institutional knowledge of end-to-end delivery. Known for treating engineering as a strategic partner to the business, he mentors diverse talent and champions scalable, secure foundations rather than point solutions. Outside of the title, his terse GitHub bio—“Build software”—hints at a builder’s mentality that favors shipping durable systems over flashy artifacts.
