The tech industry is going through one of the most aggressive talent shakeups in recent memory. Layoffs are rolling through major companies. Teams are getting smaller. And the engineers who remain are being evaluated on a metric that barely existed a few years ago: how well they use AI.
According to a former Meta engineering manager, Kun Chen, only about 2% of engineers are using AI "very effectively." That is a tiny slice. And the gap between that 2% and everyone else is already starting to shape who gets the best projects, the most job security, and the strongest career trajectory.
If you are an engineer looking for your next role, or trying to make yourself more competitive in the current market, this matters a lot.
The Productivity Gap is Real
Chen shared these numbers on the "A Life Engineered" podcast, drawing on conversations he had with CTOs across the industry. Most companies are seeing a 10% to 15% overall productivity boost from AI tools. That sounds decent on paper, but the picture gets more interesting when you zoom in.
The majority of that boost is coming from a small group of people who figured out how to integrate AI into their actual workflows, not just use it for autocomplete suggestions or quick code snippets. The rest of the engineering org is using AI in what Chen calls a "shallow way," which makes the technology look less transformative than it really is.
So while leadership sees a modest bump on average, the top performers are operating on a completely different level. And that difference is not going unnoticed.
What are the 2% doing differently?
This group goes way beyond copilot suggestions and chatbot-generated boilerplate. They have rethought how they approach their work from the ground up.
Think of it this way. The shallow users treat AI like a slightly faster search engine. The effective users treat it like a junior engineer on their team, one they can delegate to, iterate with, and build alongside. They are using agentic workflows, multi-step prompting, and context-rich sessions that go way beyond "write me a function."
Chen described this as "mastering agentic engineering," and he said the productivity gains for this group are massive. Not 10%. Not 15%. The kind of boost where a single engineer starts doing the work that previously required a small team.
Why should this matter to job seekers?
Chen said that companies are actively reallocating the most impactful projects to the 2% who are getting results. Those engineers are being given the green light to charge ahead on high-priority work. Meanwhile, larger teams that move slowly (think months to rename a button or tweak a line of text) are raising some uncomfortable questions from leadership.
CTOs are looking at those slow-moving teams and asking a pretty direct question: why do we still have this many people here?
That is not a fun position to be in as an engineer. And it is an even worse position to be in as someone who is actively job searching without AI fluency on your resume.
The companies that are hiring right now, especially the VC-backed startups building with AI at the center, want engineers who already know how to work this way. "Learning AI on the job" is not the pitch it used to be. These companies want to see that you have already figured it out.
How to Start Closing the Gap
Chen offered some practical guidance here, and it is worth paying attention to.
First, do not over-invest in specific tools. AI is moving so fast that the tool you master today might be irrelevant in six months. Instead, invest in developing a mindset of continuous learning. Get comfortable with the process of picking up new tools, testing them in real workflows, and adapting quickly when something better comes along.
Second, focus on agentic patterns. Learn how to break complex tasks into steps that an AI can execute. Practice giving AI agents rich context, clear instructions, and iterative feedback. This is the skill that separates the 2% from everyone else, and it is transferable across whatever tools become dominant next.
Third, build in public or at least document what you are learning. If you are job hunting, having concrete examples of how you used AI to ship something faster or solve a complex problem is going to stand out way more than listing "familiar with ChatGPT" on your resume.
The Bigger Picture
Chen compared the current AI shift to the industrial revolution and the early internet. Both started small, with a tiny group of early adopters who saw the potential before everyone else. And in both cases, that early adoption paid off enormously.
Engineers who figure out AI now will do more than survive the next wave of layoffs. They will become the people companies build around, recruit first, and trust to set the pace.
Nobody is getting replaced by AI, but engineers who figure out how to multiply their impact with it are pulling away from everyone else fast.
What This Means at Fonzi
At Fonzi, we work with VC-backed startups and tech companies that are building at the cutting edge. The hiring managers we talk to every day are looking for exactly the kind of engineer Chen is describing: someone who does not just write good code, but who knows how to leverage AI to move faster, think bigger, and ship with less friction.
If you are a software engineer who has been sharpening your AI skills and you are ready for your next opportunity, Fonzi connects vetted engineers with companies that value exactly that mindset. The roles we surface are curated matches with teams that care about how you work, not just what languages you know.
The 2% is not a fixed number. It is growing. And the engineers who lean in now are the ones who will define what engineering looks like going forward.
