Hire React developers who have been assessed, not just matched

Centricone places React engineers into your team, on your board and in your repository. Every candidate sits a live technical assessment with an engineer who does the work before their profile reaches you.

Screening

What we check that a keyword match does not

Every candidate sits a live assessment with an engineer who does this work. For this role, that conversation covers:

  • Component design under review — boundaries, props, and composition rather than syntax recall
  • State management judgement: what belongs on the server, in a store, or in a component
  • Performance reasoning — why a list re-renders and what they would measure first
  • Testing habits, including what they consider not worth testing

What they do once they are in your team

01

Feature delivery inside your existing component system and review process

02

Extending or replacing a design system without forking it

03

Frontend performance work against real user metrics

04

Migrating legacy interfaces route by route while both run side by side

Which level you actually need

Most briefs ask for senior by default. Sometimes that is right; often the work is better served by a mid-level engineer and a clearer specification.

Mid-level

Delivers features inside an established codebase, follows the existing patterns, and needs review on architectural decisions.

Senior

Owns a surface area, sets patterns others follow, and is trusted to make component and state decisions unsupervised.

Lead

Runs the frontend for a product: architecture, review standards, and mentoring, with accountability for delivery.

Questions about hiring React developers

Not sure what you need? Describe the work and we’ll tell you which role fills it.

A live technical assessment with an engineer who builds React professionally — a working exercise plus discussion of decisions, not a quiz. We are looking at how they reason about component boundaries, state, and performance, because those are what separate a productive hire from a keyword match.
That is the normal arrangement. They work in your repository, on your board, to your review standards. We onboard to your process rather than importing ours.
Both, and contract-to-hire in between with the conversion terms agreed up front. Which one fits depends on whether the need is a defined push or an ongoing role — we will say which we think it is.
