Hire JavaScript developers for the browser and the server
One title covers at least three different jobs. Tell us what the work is and we will name which job it is, and who we would put on it.
Get the job named first
Describe the work in a few lines. A senior software engineer replies with which job it is, and who would do it.
Where a JavaScript hire usually goes wrong
The specification is the part that failed.
Ask what happens when a value is undefined rather than null, or how the prototype chain resolves a method. That question separates candidates in a way a portfolio does not. The gap it finds shows up a month or two later, in code review, on the parts of the system nobody wants to touch.
Even a strong hire takes time. Someone excellent still spends weeks learning the domain, the deploy path and the decisions made before they arrived. That cost is real, and it is worth paying once rather than twice.
The words "JavaScript developer" cover interface state, service logic, and the tooling everyone else builds on. The title picks none of them, and three people who all fit it may be strong at very different parts. Hire against the title, judge the result on the person, and a specification problem gets filed as a hiring problem.
If a date is already promised to a board or a customer, that mistake costs twice. Once for the weeks you spent, and again for the weeks you need to recover. Naming the job first costs a conversation.
A JavaScript title does not say whether the code is typed
Stack Overflow's 2025 developer survey asked 31,771 developers which languages they had worked in extensively over the past year. JavaScript came back at 66 percent. TypeScript sat well behind it, at 43.6 percent.

| Item | Share of respondents |

| TypeScript | 43.6% |
Typed code is a requirement worth writing down and checking, because a role title does not carry it.
So a title that says JavaScript says nothing about types. If the code should be typed, tested and reviewed, each belongs in the requirement by name and has to be checked in the work itself. Ask for the types in the requirement, then ask to see a pull request where somebody argued about them. If nobody can point you at that argument, the types are a claim you have not checked.
What hiring in-house costs in calendar time
Ashby's 2026 Talent Trends Report, across 54 million applications and 93,000 jobs between January 2021 and March 2026, puts the interview loop alone at about 18 days for technical candidates who are hired, measured from the screen to the final interview. Sourcing happens before that window; an offer, a negotiation and a notice period all come after it.
Show data table
| Item | Days in the interview loop |
|---|---|
| Technical roles | 18 days |
| Business roles | 14 days |
This window covers interviews only. Sourcing, offers and notice periods sit on top of it.
None of that is wasted when the role has been named correctly. Get the job wrong and the whole window runs again, with the date you were protecting months closer, and the person already hired has to be managed out of a team that built around them. That is the case for naming the job before anyone is sourced for it.
The jobs below are what the one title is actually covering. Find the row that matches your work, then take the column it sits in.
Which JavaScript job your work actually needs
One title, several jobs. Here is what each one is, and which one we would put people on.
| The job | One framework | The browser side | The server side | Screen to schema | The language itself |
|---|---|---|---|---|---|

Behind the one title there are usually three shapes of work. The service side: logic, APIs, auth, data models, queues and integrations. End-to-end delivery: one person carrying a change from the screen to the database. And platform work: the internal tooling, deploy workflows, scripts and queue workers everyone else builds on.
Neither side of the wire is the default. Stack Overflow's 2025 survey of web technologies asked 23,678 developers what they had worked in extensively over the past year. Node.js came back at 48.7 percent, React at 44.7 percent.
We staff both. On the browser side that is React with Next.js, Remix and Preact, plus Vue, Astro, Svelte, HTMX and Alpine. On the server side it is Node.js with NestJS, Express, Fastify, Hono and AdonisJS. The stack gets chosen to fit the project rather than to fit what we already know best.
Not sure which of these your work is?
Describe it in a few lines and we will name the job and the people.
No sales sequence, and no obligation to proceed.
Vetted means nothing on its own, and a ratio of applicants rejected is not something an engineering leader can evaluate. Framework fluency is the quickest thing to test for. It is also the thing that hides weak fundamentals. What can be evaluated is the path a change takes before it lands.
How a change reaches the main branch
Reviewed
A senior software engineer reads every change
No change reaches the main branch without review by a senior software engineer, covering the approach taken and not only whether the tests went green. Branching follows GitFlow, so what sits on each branch is predictable.
Tested
Unit and integration tests run on every merge
Continuous integration gates the merge itself, running unit and integration tests. A failing pipeline stops the merge rather than raising a warning somebody has to notice.
Written down
Architecture decisions live in the specification
Decisions about structure go into the technical requirements specification with the reason beside them, so six months later why it was built that way sits in a document rather than one head.
That is our standard, and it is written down so it can be held to. Ask anyone else bidding for this work to put theirs in the same form. Compare the two.
What committing actually sets in motion
The sequence below is the one we run every time, and the part worth reading twice is the middle one. The standard a developer is judged against gets written into the engagement before they start work. It is agreed with you, not presented to you afterwards.
What this looks like from your side
The first few days
The brief
Light
You describe the work in a few lines, and we ask what the change actually touches.
How it feels
Quick, and slightly uncertain. You may not yet have a settled name for the work.
What we do about it
We name which job this is and present a shortlist, typically within a few days. If the bench does not match, we say so and recruit for the role.
Before the start
The criteria
Deciding
You choose whether to run your own technical interviews, your full hiring loop, or none of it.
How it feels
This is where it reads as a risk. You are agreeing to someone you have known a week.
What we do about it
Every developer proposed is vetted by our own technical team first, and the pass criteria for the pilot are written into the engagement before they start.
The first weeks
The pilot
Watched
You are working with the developer within days of choosing them, against criteria you already agreed.
How it feels
The hardest stretch. The work has started and the answer is not in yet.
What we do about it
This is where the criteria get applied rather than agreed.
Writing the criteria down first is what makes the judgement at the end a check rather than an argument.
One engagement where both sides were staffed together
An early-stage B2B SaaS startup arrived with a rough prototype and ten weeks until an investor milestone. Nobody in-house could build it. The real risk was spending three of those ten weeks deciding what to build.
The scope was defined and frozen in the first five days, then the backend and frontend were built in parallel with weekly demos and scope reviews. Holding the scope line was the work: every request came back with what it would cost against the deadline, and cuts were the founder's call, made in the week they came up.
What changed, against whose date

BeforeA rough prototype
AfterLive in production
The MVP scope

AfterFrozen, week one
Time to launch
Before10-week deadline
After9.5 weeks
The ten-week deadline was the client's investor milestone, set before the work started, and the two ends measured are the prototype we were handed and the production launch. Nothing tracked here moved the wrong way.
It is here for the arrangement rather than the speed. Both sides of the wire were staffed at once and moved together, against somebody else's date. That engagement was a delivered build rather than developers joining a team, so it is evidence that both jobs can be staffed and kept in step.
What happens after the launch date

*Disclaimer: These are our own operating counts. The decade figure is a single engagement that is still running.
Most engagements here continue past the launch date. The code is engineered for handoff to an in-house team when that is the direction you want, planned early, with the documentation and the runbook written while the work happens.
The longest one is still going after more than a decade. The people who have been doing this since 2015 are worth a look before you commit to anyone.
Four things set the shape of the engagement
All four can be answered before you talk to anyone.
- How many developers, and whether they join a team or form one
- Whether the work needs DevOps and QA alongside them
- How many hours of daily overlap the work genuinely needs
- How long the work runs
Two developers joining your team is a different engagement from four people forming one, at the same headcount. A full-team buildout pairs the developers with at least one DevOps engineer and one QA engineer. That changes the shape more than headcount does. Overlap is agreed at scoping, and the honest numbers are below.
Most engagements run three months or longer, because that is roughly when a new developer's productivity curve flattens out. Shorter ones make sense for a clearly-scoped pilot, for fix-it work, or for a specialist project with a defined end.
What you keep is settled from day one. Every line of code is your intellectual property. The code lives in your repositories and deploys to your cloud accounts. Documentation is yours to keep, including the operational runbook handed over at offboarding.
Answer those four and the conversation starts from a scope instead of from zero. What comes back is that scope and the people we would put on it.
All our developers are currently based in India and work Indian Standard Time, 10:00 to 19:00, which is 04:30 to 13:30 UTC. For a European team that is a substantial afternoon overlap. The exact overlap is agreed at engagement scoping. Where a live standup or sync is needed, a project coordinator can host it, or an overlap shift can be arranged on request. We do not run follow-the-sun coverage and will not claim to.
Whether this is the right call
Where we fit
You need JavaScript people on both sides of the wire, and you want the job named before anyone is assigned.
You want the review standard and the pass criteria in writing before a developer starts.
Your hours overlap ours enough to work day to day, and you would rather have that number now.
Where we are the wrong call
You need someone at a keyboard through your own night, and a few hours of daily overlap will not carry the work.
You want an outcome delivered to a scope and a date, rather than developers joining your team.
You already know the work is one framework, or one side of the wire, and the comparison above names where to go.
Two things can come back. Either we name the job and the people we would put on it, or we name someone better suited and tell you why. Neither is a price: a price needs a scope, and the scope is what the first conversation produces.
