Ex-McKinsey Partner: Why I Left Strategy Consulting For Forward Deployed Engineering - Ben Lau
Episode 7 ·
Guest: Ben Lau — Forward Deployed Engineer, Cognition
Listen
When Ben Lau rose to Junior Partner after a decade at McKinsey, he realized a fundamental tension in corporate consulting: selling high-priced strategic slide decks was becoming increasingly detached from hands-on technical execution.
Instead of remaining in comfortable upper-tier management, he made a radical choice to reset his career—taking on a coding challenge that landed him as a Forward Deployed Engineer at Cognition, the $26B startup behind Devin.
In this episode, we sit down with Ben to look at the seismic shift transforming software engineering and enterprise strategy:
We break down a lot of fascinating tech and stories:
- McKinsey To AI Startup: Why he walked away from a 10-year career as a Junior Partner to jump directly into the high-stakes world of frontier AI deployment.
- The Rise Of The FDE: How Forward Deployed Engineers are replacing traditional management consulting by delivering working software instead of expensive slide decks.
- Cloud Agents Vs. Local Tools: Why local coding assistants fall short on massive enterprise repositories, and how cloud-hosted agents leverage elastic virtual machines to handle complex parallel workloads.
- Eliminating AI Slop: The exact architecture Cognition uses to keep agents from duplicating code, from pre-indexing codebases with DeepWiki to enforcing multi-agent dialectic code reviews.
- Non-Engineers Writing Code: How non-technical sales and operations teams are using Devin to diagnose system bugs, run tests, and submit functional pull requests directly.
Beyond the technical discussion, this chat is an inspiration when it comes to shifting careers! It shows that you don’t have to be a deeply technical person to be able to work with code anymore! It is a story about finding out what is important to each person, how to provide value, and how to adapt to modern tools to solve those problems.
Enjoy!
