For interfaces that stay fast as the product grows
Hire React Developers
Most teams do not need someone who knows React's API surface. They need someone who can reason about state ownership, rendering cost and the messy backend a real interface has to survive. These engineers are selected against that failure mode with real state-management, rendering-performance and accessibility tasks, and folded into the review rhythm your team already keeps.
- Profiles typically within two business days
- Replacement Assurance: If an engineer is not the right fit, a replacement from our own team starts within ten business days of your request, at no extra cost
- You interview before placement if you want to
- At least four hours a day inside your core working hours. Two hours plus a daily written handover for the US West Coast
- 14-Day Risk-Free Trial: For your first engineer on a time-and-materials engagement. Up to 14 calendar days or 80 logged working hours, whichever comes first. End within the trial and pay nothing for trial hours. Continue beyond it and those hours are billed at the agreed rate. Unpaid trial work remains ours if you stop
How we evaluate a React engineer
The tasks, the signals and the onboarding, walked through by the people who run them.
90 secSample frame · video pending01Published, not promised
The assessment behind every engineer we send.
Anyone can claim their React people are vetted. Here is the vetting itself: five competencies, the task behind each, and the tell that ends a candidacy. Reuse any of it in your own interviews.
What we listen forWhether they can reason about where state should live and why.
Given a form with five interdependent fields and a slow validation API, walk us through your state management approach and where you would draw component boundaries.
- What strong sounds like
- Separates local UI state from server state explicitly, and can defend why a boundary sits where it does.
- What gives us pause
- Reaches immediately for a global store without asking whether the state needs to be global at all.

02Who you actually meet
The bench, priced by seniority.
Three seniority tiers, priced honestly, and the engineers who fill each one today. Real names and photos take their place as soon as we can share them, and the standard stays exactly the same.
Engineer
Features scoped tightly enough to ship inside your review bar, every time.
The right first hire when your seniors already set the standard.
$2,400–3,100per month
Senior
The hard module nobody else wants to own, taken end to end.
Ownership of a surface, without adding a manager to your headcount.
$3,400–4,300per month
Lead
The workstream's decisions, made daily, so nothing waits on a meeting.
One accountable voice for a pod or initiative that can't afford to drift.
$4,600–5,800per month

03From stated problem to first change
Four steps, each closing on evidence.
No black-box shortlisting. Each step below closes with something you can inspect, and you can stop at any of them without owing us anything.
Define the interface problem
We map what the interface actually needs to do under real data and real users. The role brief describes the problem to solve, not a checklist of React features.
A brief your leads signMatch against your stack
Candidates are screened against your component library, your state management choices and your review culture. Three engineers who fit beat thirty who list the right buzzwords.
Three fits, not thirty CVsAssess on the real tasks
Your team can watch the component-review and testing exercises live rather than trusting a score. You see judgement under uncertainty, not a rehearsed portfolio walkthrough.
Evaluation you can watchOnboard inside your process
Access, standards and a first bounded change to a real component. If the engineer ever leaves, continuity cover makes the handover our responsibility, not your sprint's.
A merged change in week one
04Evidence and proof
Engineers who made the interface fast and honest.
React proof is render performance under real data and accessibility that holds up unprompted. Every record here waits for written client approval before production.
Explore case studies
A dashboard that stopped freezing under real customer data volume.
Aster North's admin dashboard worked fine in demos and froze with real customer data loaded. One embedded React engineer diagnosed the render chain and fixed it inside a sprint.
- Render time under real load
- Cut sharply
- Time to first merged fix
- One sprint
The performance diagnosis in the interview was more thorough than what our previous agency delivered as a paid engagement.

05Three shapes, one standard
Add an engineer, a frontend pod, or a practice.
Start with one engineer and grow on evidence, or take a pod that owns the interface layer outright. When the honest need is product delivery rather than a seat, we say so.
- Team extension
One named engineer
A single React specialist inside your direction and your reviews. The smallest commitment and the most common starting point.
- Delivery pods
A frontend pod
A pod with its own lead that takes the component library and its roadmap off your plate. You set priorities and acceptance while the pod carries delivery.
- Product engineering
The practice, not the person
If the honest need is shipping a product rather than filling a seat, product engineering takes delivery accountability instead.
06Straight answers
Asked before a React hire is signed.
01What does a React engineer actually do day to day?
Builds and maintains component architecture, manages state boundaries between local and server data, profiles and fixes rendering performance, and keeps interfaces accessible and tested. The unglamorous majority of the work is consistency across a growing component library.
02Do you hire for Next.js specifically, or React more broadly?
Both, matched to your actual stack. Next.js brings routing, server components and rendering strategy decisions that plain React does not, so the evaluation adjusts to whichever your codebase runs.
03Can we run our own interviews as well?
Run as many of your own rounds as you like. Most clients pair our published ledger with one culture conversation of their own, and some sit in on our technical assessment directly.
04How fast can a React engineer start?
Days to a shortlist, because React matching starts from a bench we already evaluate continuously. After your interviews, the start date depends mostly on your repository access process.
05Who manages the engineer day to day?
Your leads run the standups, the reviews and the roadmap. We stay responsible for continuity and replacement, which is the part a direct hire never gives you.
06What if the engineer is not the right fit?
Tell us inside the first weeks and the swap is on us. The next candidate arrives briefed on exactly why the first match missed, which is why second matches almost always hold.
07Do your React developers use AI coding assistants?
Yes, openly and under governance. AI accelerates component scaffolding and test generation, while the engineer stays accountable for every interaction pattern, dependency and merge. You get the speed without inheriting unreviewed machine output in your interface code.
08How does pricing work for a hired React engineer?
Each tier above carries its band, confirmed per engineer with the shortlist. Nothing is owed before an interview, and notice periods replace lock-ins.
