The Role
Principal Full Stack Engineer responsible for architecting, developing, deploying, and modernizing internal platforms and AI-enabled products. The role is 70–80% hands-on coding, with ownership of architecture, engineering standards, governance, and technology strategy. They will mentor senior engineers, partner with product managers and stakeholders, establish reusable components and processes, guide technology adoption, and drive scalable software engineering practices across the organization.

About the Role
Our client is a top-tier strategy and management consulting firm, the kind that competes with McKinsey, BCG and Bain for C-suite work. This role isn't on the client-facing side. It sits in their internal platform and product group, which builds and runs the 30+ products their consultants use to do that work. Your customers are the firm's senior partners, and they notice when things break.
The portfolio falls into three buckets. Some products are legacy and need to be modernized. Some are adding AI features and AI tooling. The rest are new, built from AI use cases still being defined. They're hiring Principal engineers first, then building teams around them, so you'd get in early.
They want engineers who take a product and run it, not ones who wait for a ticket. Expect 70% to 80% of your time in the code, with the rest on architecture and tech leadership. You'll mentor 5 to 7 senior engineers and work closely with product managers. Documentation won't always exist, and when it does, you'll probably be the one improving it.
The stack is React, C# and Python, in a Microsoft/Azure shop. You won't own infrastructure, since another team handles that. They use AI tools daily and expect you to as well.
