Navigating the AI Era: Insights for Senior Engineers and R&D Leaders

A senior technical leader with twelve years at a large tech company reflects on the anxiety caused by AI's rapid productivity gains, noting that AI can triple a junior colleague's output in tasks like code refactoring and performance tuning.

The author identifies three key capabilities that propelled his career from P7 to P8: business insight, decision‑making authority, and mentoring junior talent.

He advises peers to (1) embrace AI as a helper, (2) shift focus from writing code to making strategic technical decisions, and (3) broaden expertise horizontally into business domains to remain indispensable.
