Agent Engineering: A New Archetype in Product Leadership

by Chris Zachary, June 2025

✨ Welcome to the Age of Cognitive Architecture

I just watched Harrison Chase’s LangChain Interrupt 2025 keynote—and it hit me: we’re not just in a tech cycle. We’re at the edge of a new discipline.

This isn’t about coding faster or “using AI.”

It’s about designing cognition—integrating memory, tools, feedback, and reasoning into fluid, intelligent systems.

LangChain calls the person who does this an Agent Engineer. And that framing clicked with something I’ve been circling for months:

→ What is the optimal product leader in an AI-native world?

It’s not someone who’s just technical. Or just strategic. Or just human-centered.

It’s all three—cross-disciplinary, high-context, deeply synthetic.

🛠️ What Is an Agent Engineer?

In his keynote, Harrison Chase outlined four core capabilities of a production-ready agent engineer:

Prompting → Engineering precise natural language inputs & outputs
Engineering → Building tools, memory layers, and orchestration flows
Product Design → Translating messy user needs into usable agents
Machine Learning → Evaluating, fine-tuning, and improving agent performance

This isn’t just a backend dev with LLM access.

Agent Engineers sit at the intersection of UX, infra, ML ops, and product strategy.

They’re not building features.

They’re architecting cognition.

🧭 The 1% Product Leader, Reimagined

This aligns perfectly with Ian McAllister’s classic:

👉 What Distinguishes the Top 1% of Product Managers

McAllister highlights three traits of world-class PMs:

Adaptability – thriving amid change and ambiguity
Strategic Depth – playing the long game with clarity
Execution Mastery – driving focused results

It’s the same for Agent Engineers. The Venn diagram is becoming a circle.

The best PMs of the next decade may not just lead AI systems—they’ll design them.

🔄 Why This Role Matters Now

LLMs are powerful—but alone, they’re blunt instruments.

The magic happens when we wrap them in context-aware systems:

🧠 Dynamic context windows
🗂️ Episodic memory
🔁 Human feedback loops
🧰 External tool integrations
🧪 Continuous evaluation + observability

LangChain is building exactly this:

LangGraph → a framework for structured agent workflows
LangSmith → tooling for observability, debugging, and evals

Together, they create a foundation for engineering agency into software.

🧩 The Multidisciplinary Stack of the Future

To thrive in this new role, range is required.

An Agent Engineer blends:

⚙️ Technical Skill – APIs, orchestration, memory handling
🧭 Product Intuition – knowing what matters to the user
🧱 Systems Design – building resilient, layered logic
🗣️ Narrative Fluency – framing, explaining, aligning teams

The best builders now?

They go wide and deep—holding complexity without drowning in it.

🚀 Final Thought: The Craft Is Emerging

I’m convinced we’re watching the emergence of a new craft.

Not traditional software. Not just ML. Not just design.

It’s agent-oriented cognition design.

And it calls for a new kind of generalist:

One who can prototype, orchestrate, evaluate, and deliver meaningfully intelligent systems.

It’s an amazing time to be alive—and building.
