Full Stack Developer Staffing, One Engineer From UI to Database

KORE1’s full stack developer staffing places engineers who own the whole vertical, from the UI a user clicks to the API and database behind it, on contract or direct hire, with a 17-day average IT time-to-hire.

One Person, Every Layer. That’s the Whole Idea.

A full stack developer is the engineer who can follow a single feature all the way down. They build the button a user clicks, the endpoint it calls, and the table that stores what happens next. No handoff. No ticket waiting in another team’s queue while a launch slips.

That breadth is the selling point and the trap. The same word, full stack, covers a developer who genuinely ships across the whole vertical and one who knows a little React and Googles the rest of the backend. Both will say they’re full stack on a resume. Only one of them keeps a small team moving without a second hire. Telling them apart in a 45-minute interview is the part most hiring managers get wrong, and it’s the part we screen hardest for.

There’s a scoping question worth answering before the search even opens. Do you actually need one versatile owner, or two specialists? If the build is mostly websites and web apps, our broader web developer staffing spans the whole web stack. A front-end developer who lives in the UI and a backend developer who lives in the services will each go deeper than a generalist on their half. A full stack hire trades some of that depth for range and speed. We’ll help you decide which shape fits, then source to it.

The Stack One Person Owns

Full stack means moving up and down these layers in the same workday. The orange line is the one engineer threading through all of them.

Four Kinds of Full Stack Hire

They all say full stack on the resume. Underneath, they sit in different places on the stack. The tag tells you where.

balanced

Product Full Stack

Even across UI and services, the developer who can take a feature from Figma to production alone. The default hire for most product teams shipping a roadmap.

ui·leaning

Front-of-Stack Full Stack

Strongest in the browser, fluent enough in the API to not be blocked. Great when the product lives or dies on the interface, with overlap into our front-end staffing.

api·leaning

Back-of-Stack Full Stack

Lives closer to data and services, builds a clean UI when asked. The right call for data-heavy tools, and a short step from our backend staffing bench.

founding

Founding / Startup Full Stack

One engineer, the whole product, plus a little infra and a lot of judgment about what to skip. Common in our startup staffing searches.

When Full Stack Is the Right Hire, and When It Isn’t

We turn away more full stack searches than you’d expect. Here’s the honest version of when one versatile engineer wins, and when you really want a specialist.

hire full stack

Early product, small team, fast roadmap. When one person can build a whole feature without waiting on anyone, you ship in days instead of sprints. A full stack hire also costs roughly 10 to 15 percent more per hour than a single specialist while covering work that would otherwise need two people. For a seed-stage startup or a lean internal tools team, that math is hard to beat. Three of our last six startup placements were full stack developers hired exactly for that reason.

it depends

Mid-sized team, real but bounded scope. This is where contract-to-hire earns its keep. You get a full stack developer producing on day one, and a few months to learn whether the breadth they claimed holds up under your actual codebase before anyone signs a permanent offer. Most of the messy cases land here, and they’re fine, as long as the role is scoped to one clear track instead of quietly becoming three jobs.

hire a specialist

Deep, specialized work at scale. A full stack generalist is the wrong hire when the problem is a payments service handling millions of transactions, a design system three teams depend on, or a data platform with real performance constraints. Backend specialists out-earn generalists by around $35K at the median for a reason. The depth is worth it. When you tell us the work is genuinely specialized, we’ll point you to front-end, backend, or software engineer staffing instead, and say so plainly.

Why KORE1 for Full Stack Developer Staffing

We’ve placed technology talent for two decades. Full stack isn’t a keyword we bolted onto a services page. It’s a vetted bench that sits inside our IT staffing practice, screened by recruiters who’ve run enough technical searches to hear the difference between range and bluffing.

Every developer we submit gets screened on the work, not the resume. We walk through a feature they built end to end. The UI decisions, the API they wrote to feed it, the schema they had to change three weeks in when the requirements moved. A real full stack developer can narrate that whole path without flinching. The pretenders go quiet somewhere around the database, and we catch it before you spend an interview loop finding out.

We staff full stack roles across more than 30 U.S. metros and place remote coast to coast. The stack you run shapes the search, so our Python, PHP, and software engineer benches feed straight into full stack work, and we lean on our front-end and backend pools when a role tilts toward one end. Before an offer goes out, a lot of teams calibrate the number against our salary benchmark tool and our full stack developer salary guide so it lands on the first try.

Common Questions

How much does it cost to hire a full stack developer through a staffing agency in 2026?

Mid-level full stack developers generally land in the $115K to $150K base range in 2026, with senior and lead developers running $150K to $200K and higher once equity and bonus stack on. Contract rates for experienced full stack developers typically fall between $80 and $150 an hour, depending on stack, seniority, and city. One useful rule of thumb: a full stack hire runs about 10 to 15 percent more per hour than a single specialist, but covers work that would otherwise take two. Our full stack developer salary guide breaks the numbers down by role and region, and benchmarking against stale data is the most common reason a finalist walks.

How is a full stack developer different from front-end and back-end?

Full stack means one developer covers the whole vertical, top to bottom. Front-end specialists stop at the UI. Back-end specialists own the services and data underneath. What you’re really choosing is range against depth. A full stack hire can build a whole feature alone, which is gold on a small team. Specialists go deeper on their half, and that matters when the UI is a complex design system or the backend is handling serious scale. We help you scope honestly, then point you to front-end or backend staffing when a specialist is the better call.

How long does a full stack developer search take?

Our average time-to-hire across IT placements is 17 days. Mainstream full stack searches on common stacks like React with Node or Python move fastest, while a specific combination, say Next.js with a typed backend and real AWS depth, can run three to five weeks. Searches close quickest when the loop is two rounds, the role is one clear track instead of full-stack-plus-DevOps-plus-data, and the comp is benchmarked to the current market.

Which stacks and frameworks can you staff for?

Yes to the common ones, and the combination genuinely shapes the search. We staff JavaScript and TypeScript full stack on React, Next.js, Vue, and Angular up front with Node behind, plus Python with Django or FastAPI, .NET, Ruby on Rails, and Java with Spring. The MERN and Next.js plus TypeScript combinations are the deepest talent pools and fill quickest, in line with the most-used technologies in the Stack Overflow Developer Survey. We source to the stack you actually run, and we’ll tell you when a niche pairing is going to stretch the timeline.

Is one full stack developer really cheaper than hiring two specialists?

Usually, for early-stage and smaller-scope work. One full stack developer costs a bit more per hour than a single specialist but does the work of two, so for an MVP or a lean team the savings are real. The math flips when the work gets deep. A payments platform at scale or a design system three teams rely on rewards specialists who go further than any generalist can, and the premium pays for itself. We’ll be straight with you about which side of that line your work sits on.

Beyond writing code, what should we screen full stack developers for?

Honest range is the big one. Plenty of developers claim full stack and turn out to be a strong front-end engineer who can follow a backend tutorial, or the reverse. We screen by walking through a feature they shipped across both ends and pushing on the half they mention less. Past that, we look for judgment about where to spend effort, comfort moving between UI and data in the same day, and the maturity to flag when a problem actually needs a specialist. Tell us your stack and your roadmap, and we’ll build the screen around it.
