What Hiring Managers Actually Look for in a Next.js Developer
What Hiring Managers Actually Look for in a Next.js Developer
Quick answer: Hiring managers want to see three things from a Next.js developer: shipped product experience with real users, solid TypeScript competency, and genuine awareness of performance and SEO. Everything else is secondary.
I've been a Next.js developer for over seven years. I've worked at Goldman Sachs, BrightEdge, and now Atlan. I've also reviewed enough portfolios and codebases as a senior engineer to tell you what actually moves the needle when you're being evaluated. This post is for developers who want the unfiltered version.
Key Takeaways
The Portfolio vs. Resume Divide
This is the most consistent signal I see when evaluating developers. A GitHub full of "todo-app-with-next" and starter template forks tells me you've been learning. One shipped Next.js app with a real domain, real users, and a README that explains your technical decisions tells me you've been building.
It's not about commit count. It's not about stars. It's about evidence that you've dealt with real constraints: production deploys, performance under real traffic, integrating third-party APIs that don't behave the way the docs say they will.
When I'm reviewing someone's work, the first thing I check is whether anything they built is actually live. If the answer is no, that's a gap. Not a dealbreaker, but a gap.
What "shipped" actually means
Shipped means a real URL, not a Vercel preview link. It means the app handles edge cases. It means there's a README that isn't just the default Next.js boilerplate text. Explain why you made the routing decisions you made. Explain what you'd do differently. That kind of reflection is what separates someone who followed a tutorial from someone who understood what they were building.
TypeScript Is a Baseline Now, Not a Differentiator
Most teams in 2026 use TypeScript. Being shaky on types isn't a quirk anymore. It's a red flag.
I'm not talking about basic prop typing. I'm talking about generic types, discriminated unions, and properly typing API responses, especially when the shape of that response can vary. If you're casting everything to any or writing as SomeType everywhere without understanding why, experienced reviewers will notice.
The developers who impress me are the ones who use TypeScript to make their code self-documenting. A well-typed API client or a properly typed server action tells me you understand your own codebase. That matters more than whether you've memorized the TypeScript handbook.
A specific thing to practice
Write a typed fetch wrapper that handles error states and success states as a discriminated union. If that sentence confused you, that's your starting point. Most Next.js candidates skip this because tutorials don't cover it. That's exactly why it's worth knowing.
App Router vs. Pages Router: Know the Why, Not Just the What
Hiring managers will ask about App Router. But the answer they're looking for isn't "yes, I've used it." They want to know whether you understand why it exists.
App Router introduced React Server Components, nested layouts, and native streaming support. These aren't cosmetic changes. They fundamentally change how you think about data fetching and component boundaries. If you're using App Router but still fetching everything client-side because that's what you know, you've missed the point.
Know the tradeoffs. Server Components can't use browser APIs or React hooks. Client Components re-introduce the client boundary. Streaming with Suspense changes how loading states work. Understanding these tradeoffs — and being able to articulate when you'd reach for each approach — is what signals a senior-level grasp of the framework.
Pages Router isn't dead
A lot of production Next.js apps still use Pages Router. Don't pretend it doesn't exist. Being able to work in both, and knowing when a team might reasonably stick with Pages Router, shows pragmatism. Hiring managers notice that too.
Performance and SEO Are Basic Competencies
This is where most Next.js candidates reveal they're more junior than they think. Performance and SEO awareness are not advanced topics. They're baseline expectations for anyone calling themselves a Next.js developer.
The framework gives you the tools: next/image for optimized images, next/font for font loading without layout shift, the Metadata API for structured SEO, and built-in Core Web Vitals reporting. If you haven't used these, you haven't used Next.js seriously.
Interviewers will ask about Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint. They want to know if you've actually measured these things in a real project, not just recited what they stand for.
What I tell junior developers
Run Lighthouse on something you've built. Fix what it flags. Do that three or four times across different projects, and you'll have concrete examples to talk about in any interview. Most candidates skip this step entirely.
The AI Integration Angle in 2026
This is the differentiator right now. Teams are actively looking for Next.js developers who can build LLM-powered features — not just developers who've used ChatGPT.
Practically, that means: API routes that call OpenAI or Anthropic, streaming responses using server-sent events or the Vercel AI SDK, and understanding the edge runtime tradeoffs when you need low latency. It also means knowing when to run inference on the edge versus calling an external API, and how to handle token limits and rate limits gracefully in a production app.
I've built several projects combining Next.js with LLM backends. The developers who can do this fluently — who've dealt with streaming latency, prompt engineering for structured outputs, and error handling when the model returns something unexpected — are genuinely hard to find. If you can show that experience, you stand out.
What Doesn't Actually Matter Much
I'll save you some time. Deep next.config.js mastery is not a meaningful signal. Exhaustive knowledge of every Next.js feature — including ones you'd never use in a real project — doesn't impress anyone. And deep webpack knowledge is increasingly irrelevant as Turbopack continues to replace it.
Hiring managers care about outcomes. They care about whether you can ship something that works, performs well, and that other developers can maintain. The framework is a tool. Know your tools well, but don't confuse tool knowledge with engineering judgment.
Portfolio Advice: One Live App Beats Ten Clones
If you're building your portfolio now, here's what I'd actually do. Pick one project. Make it something you'd use yourself or something that solves a real problem. Deploy it on a real domain. Write a README that explains your architecture decisions, what you'd do differently, and what technical problems you ran into.
That single project, done seriously, is worth more than ten tutorial clones across ten repositories. Quality signals judgment. Volume signals busywork.
A Note for Freelancers
Freelance clients don't care about your Next.js version history. They care whether the site is fast, shows up in Google, and doesn't require a specialist to update. When you're pitching freelance work, frame your Next.js skills in those terms.
Fast: talk about image optimization and Core Web Vitals scores you've achieved. Indexable: talk about the Metadata API and server-rendered content. Maintainable: talk about clean component structure and documentation you leave behind.
That framing converts. The technical depth matters for getting hired at a company. For freelance clients, the outcome is what sells.
The Honest Summary
Here's what I'd tell someone getting ready for a Next.js interview or putting together a freelance pitch:
Ship something real and put it on the internet. Know your TypeScript well enough that it makes your code better, not just valid. Understand App Router deeply enough to explain the tradeoffs. Know your Core Web Vitals. And if you can integrate an LLM into a Next.js app cleanly, say so explicitly — because that skill is in demand right now.
The developers who stand out aren't the ones who've memorized the most. They're the ones who've built the most, reflected on what they built, and can explain the reasoning behind their decisions.
That's it. Everything else is noise.
