For interfaces that hold up on the device a customer actually owns

Hire Frontend Developers

The gap between a frontend that looks right in a demo and one that holds up on a customer's actual device is where most interface problems live. These engineers are matched to that gap, evaluated on the work above, and onboarded inside the process your team already runs.

  • 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

01Published, not promised

The assessment behind every engineer we send.

Frontend vetting is usually a portfolio glance. Ours is published: five competencies from design-file judgement to device debugging, with the disqualifying answers stated.

What we listen forWhether their styling scales past the first ten components.

The task we set

A design system's spacing values have been hard-coded across forty components and a rebrand just changed all of them. Walk us through how you would have prevented this.

What strong sounds like
Describes design tokens and a systematic approach to shared values, and can explain the actual cost of the hard-coded approach.
What gives us pause
Proposes a find-and-replace across the codebase without addressing why the values were not centralised in the first place.

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.

$2,300–3,000per 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.

$3,300–4,200per 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.

$4,500–5,700per month

03From stated problem to first change

Four steps, each closing on evidence.

The path from brief to first merged interface change runs in four inspectable steps. Each closes with evidence, none obliges the next.

  1. Define the interface problem

    We map what the interface actually needs to hold up under real devices and real users. The role brief describes the problem to solve, not a component library preference.

    A brief your leads sign

  2. Match against your stack

    Candidates are screened against your design system, your framework and your review culture. Three engineers who fit beat thirty who list the right CSS frameworks.

    Three fits, not thirty CVs

  3. Assess on the real tasks

    Bring your designers to the accessibility and design-collaboration exercises and judge the collaboration yourselves. You see judgement about real usability, not a rehearsed portfolio walkthrough.

    Evaluation you can watch

  4. Onboard inside your process

    Access, standards and a first bounded change to a real interface. With continuity cover, a departing engineer is our gap to close before it reaches your release calendar.

    A merged change in week one

04Evidence and proof

Engineers who tested on the device customers actually own.

Frontend proof is interfaces that hold up cross-device and accessibility that works unprompted. Every record here waits for written client approval before production.

A rebrand that took a day instead of a week because of design tokens.

Koru Health's spacing and colour values were hard-coded across dozens of components. An embedded frontend engineer introduced design tokens ahead of a rebrand, cutting the actual rebrand work sharply.

05Three shapes, one standard

Add an engineer, a frontend pod, or a practice.

One engineer in your design-review loop, a frontend pod owning the interface layer, or the product practice when the whole surface needs delivering. Honest routing between the three.

  • One named engineer

    A single frontend specialist inside your direction and your reviews. The smallest commitment and the most common starting point.

    Team extension

  • A frontend pod

    Engineers and a lead who own the interface layer end to end. You set priorities and acceptance while the pod carries delivery.

    Delivery pods

  • The practice, not the person

    And if what you truly need is a finished surface rather than another seat, product engineering owns that delivery instead.

06Straight answers

Asked before a frontend hire is signed.

What does a frontend engineer actually do day to day?

Builds and maintains the interface layer, keeps design system values centralised rather than hard-coded, debugs cross-device issues, and treats accessibility and perceived performance as defaults. The unglamorous majority of the work is the interface holding up on devices nobody tested on directly.

Do you hire for React, Vue or a specific framework?

Matched to your actual stack. The evaluation focuses on layout architecture and cross-device judgement, which transfers across frameworks, then confirms familiarity with whichever your codebase runs.

Can we run our own interviews as well?

Yes, and the published tasks travel well into client-run loops. The accessibility review exercise in particular gets reused by clients for their own future hiring.

How fast can a frontend engineer start?

Days to a shortlist off the standing bench. Design-tool and repository access on your side usually sets the real start date.

Who manages the engineer day to day?

Your design and engineering leads direct everything daily. We stand behind the person: continuity, payroll, replacement, transitions.

What if the engineer is not the right fit?

Say so in the first weeks and the swap is ours to fund, informed by exactly which expectation missed.

Do your frontend developers use AI while building interfaces?

Yes, where it genuinely helps. AI speeds up markup scaffolding and utility styling; the engineer personally owns accessibility, cross-browser behaviour and the conversation with your designers. The judgement calls that make an interface feel right stay human.

How does pricing work for a hired frontend engineer?

The bands above are the frame; the shortlist carries exact figures. Monthly per engineer, no placement fee, notice-period terms.
