The Unbundling of the Senior Engineer

For most of my career, I took pride in being a craftsman. My value was in the deep inventory of knowledge I held in my head—the syntax, the quirks of a framework, the clever algorithms. This was the mark of a senior engineer: the ability to build anything from first principles, by hand.

But my recent journey of building fully autonomous AI systems has led me to a significant realization: the role of the senior engineer is being unbundled.

The skills that once made a great engineer are not disappearing, but they are being separated and assigned to the entity best suited for the job:

Rote Memorization & Syntax Generation: This is now the machine's job. An AI can recall and write boilerplate code with near-perfect accuracy, freeing up human cognition.
Architectural Vision & System Design: This remains the human's job. It is the art of seeing the whole system, asking the right questions, and making the critical trade-offs.

This isn't a story of replacement, but of leverage. By consciously delegating the machine's work to the machine, I've found I have more time and energy to focus on the uniquely human work of architecture. My work has become more creative, more strategic, and more enjoyable.

I've come to call this new practice "Just-In-Time (JIT) Competence." It's the shift from valuing the inventory of knowledge in my head to valuing the process by which I can acquire and apply any knowledge, at any time.

The core skills I now cultivate are:

Inquiry: The ability to ask the right questions to an AI to generate a robust and secure solution.
Verification: The discipline to design the tests that prove the AI's solution is correct and manage its risks.
Integration: The wisdom to architect how that solution fits sustainably into the larger system.

This has been a deeply rewarding evolution, moving from a craftsman of components to an architect of systems. It feels like the natural next step in our craft.

I'm curious—for the other experienced engineers out there, have you felt this unbundling in your own work? How has it changed the way you see your role?
