Flutter Developers
Flutter engineers working your British day. Flutter draws its own widgets, so a design-heavy product looks identical on both platforms without per-platform fixes, which is usually why a UK team picks it over the alternatives.

Vetting
You see two people - not 200 CVs.
Engineers vet engineers
A senior engineer runs a live technical conversation on the candidate's real stack, not a recruiter working from a keyword list.
Live coding, not take-homes
Real problems solved in front of an assessor, with anti-cheating checks. You see how they actually work, not what they submitted overnight.
A full profile, not a CV
Every candidate arrives with a CV, interview summary, coding-test breakdown and rate in pounds. You decide on evidence.
Every tab is a stage a candidate has to clear. Six of them, all run by our own internal engineers at Cloud Employee, before you see a name.

Got questions?
The questions CTOs and founders ask.
01How much does it cost to hire a Flutter developer in the UK?
For most roles, 50 to 75% less than the full cost of a comparable British hire, including salary, employer national insurance, pension, recruitment fees and overheads. Yes, we place UK-based Flutter developers. Most clients still end up in Eastern Europe, the Philippines or Latin America, because the talent is comparable and the price is not, and Eastern Europe overlaps a British day almost completely. What you are buying is the strongest quality-to-cost ratio we can find, not a location, geography is how it is achieved. Flutter is young enough that Britain has only a small pool of senior cross-platform developers.
02What is Flutter and why do teams choose it?
Flutter is Google's toolkit for building natively compiled applications for mobile, web and desktop from a single Dart codebase. Teams choose it because one team ships to iPhone and Android at once, with an interface drawn by Flutter's own rendering engine that looks identical on both. Hot reload keeps the feedback loop tight, and the widget model makes interfaces composable. But you take a dependency on Dart and on Google's continued investment, and platform-specific features still need native code. If your product is one platform only, a Swift or Kotlin team may serve you better.
03What skills should I look for in a Flutter developer now?
State management judgement, performance literacy and release discipline matter more than knowing every widget, because widgets are exactly the sort of thing AI assistants now recall perfectly. A strong Flutter developer can explain why they reach for a particular state approach and what it costs, since every option trades boilerplate against magic. They should understand the rendering pipeline well enough to hunt jank and diagnose dropped frames with profiling tools rather than guesswork. Shipping matters too, so look for release-train experience on both stores. Ask how AI fits their workflow, the best generate scaffolding while owning architecture.
04How do I assess a Flutter developer, and what should I ask?
Give them a small feature to build or review in a pairing session, and pay most attention to how they structure state and explain trade-offs. Useful questions include when they would choose Flutter over native and when they would not, and how they would track down a dropped-frame problem. Ask what lives in native code in their current product, anyone who says nothing has not gone deep. Encourage them to use their usual AI tools and watch the checking behaviour, not the generation. A candidate who interrogates an assistant's rebuild behaviour works the way modern mobile teams work.
05Are Flutter developers in demand, and is it worth building on?
Demand is strong wherever product teams need both major platforms without funding two native teams, which describes most startups and a growing share of established companies. Flutter earns its keep when your product's value is features and iteration speed rather than deep platform integration, think consumer apps, internal tools and companion apps. It is a weaker fit when you need the newest platform capabilities on day one. The AI wave has not diminished it, assistants speak Dart fluently, leaving the scarce skill exactly where it was, in architecture and performance judgement.
06Do your developers use AI tools, and how do you know the code is sound?
Yes, and in mobile work the question is really about what survives contact with a device, because plausible generated code and smooth-scrolling code are different things. We assess whether candidates use AI tooling well, and in Flutter that means watching what they do after generation, profiling the screen an assistant produced, checking rebuild scope, testing on a low-end device rather than the simulator. Syntax recall is cheap now, the engineering is in judgement calls a model cannot make about state, navigation and performance budget. We hold ourselves to the same standard, screening with AI while a human decides.
07How does Cloud Employee vet Flutter developers?
The process is CTO-led, and for Flutter it centres on a live pairing session with a senior engineer, because mobile craft shows up in conversation with running code. Around that sit a technical assessment, a cultural fit screen and a psychometric assessment designed for software engineers. We look for shipped apps on both stores and honest answers about where Flutter fights you, rather than certificate collections. AI helps us screen across candidate data, but no algorithm makes the call, a person does. Retention proves the filter works, 97% of engineers stay beyond two years.
08How quickly can a developer start, and how does the engagement work?
You are typically interviewing matched candidates within 7 working days of a requirements call, and developers are often embedded and pushing code within about two weeks. From there it is a rolling monthly contract with 30 days' notice, one monthly fee, and no placement charges. You can scale up or down as the work changes, and you pay nothing to interview.
09What happens if the developer is not the right fit?
There is a two-week money-back guarantee, and if you want to continue we replace the developer free of charge. In practice this rarely comes up, because you interview a shortlist of two candidates who have already passed a CTO-led technical assessment and a live pair programming session, so the fit question is largely settled before anyone starts.
