For one codebase that has to feel native on both platforms
Hire Flutter Developers
One codebase across iOS and Android sounds simple in theory. In practice a widget tree rebuilds too often, a native SDK has no plugin, or a feature quietly behaves differently on the two platforms it was supposed to unify. These engineers are tested against those exact gaps, then placed to keep one codebase feeling native on both.
- 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 Flutter 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.
The Flutter bar is published, not assumed: five competencies, the exact task behind each, and the shortcut that ends a candidacy. Most interviews ask about widget names. This one asks whether the app actually feels native on both platforms.
What we listen forWhether they can trace an unnecessary rebuild, not just wrap widgets in const.
A list scrolls janky because the whole widget tree rebuilds on every state change, even for rows that didn't change. Diagnose and fix it.
- What strong sounds like
- Identifies the specific state dependency forcing the full rebuild and scopes it down with the right widget boundary.
- What gives us pause
- Wraps everything in const or RepaintBoundary without identifying which widgets were actually rebuilding and why.

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 four steps below are built around real platform behaviour, not a catalogue of widgets used before. Each one ends with something concrete, and walking away costs you nothing.
Define the platform problem
We map where your app's performance or platform parity is actually breaking down. The brief names that gap, not a list of Flutter widgets to know.
A brief your leads signMatch against your app
Candidates are screened against your actual state-management approach, your native integrations and your review culture. Three engineers who understand your app beat thirty who list Flutter on a CV.
Three fits, not thirty CVsAssess on the real tasks
Bring your own engineers to the rebuild-performance and platform-divergence exercises. Judgement under real cross-platform constraints is visible here, not a rehearsed demo.
Evaluation you can watchOnboard inside your process
Access, standards and a first bounded fix shipped to both platforms. Continuity cover means a departure is our scheduling problem, resolved before it touches your release.
A merged change in week one
04Evidence and proof
Engineers who made one codebase feel native on both.
Flutter proof is platform parity that holds up under real use, not a demo that only runs well on one device. Every record here waits for written client approval before production.
Explore case studies
A scroll that stopped janking once the widget tree stopped over-rebuilding.
Pillar Learning's course list janked badly on mid-range Android devices while running smoothly on the team's own phones. An embedded Flutter engineer traced it to unnecessary widget rebuilds and fixed it without a redesign.
- Frame drops on mid-range devices
- Eliminated
- Redesign required
- None
He found a platform-divergence bug we had been quietly working around for two releases instead of fixing.

05Three shapes, one standard
Add an engineer, a mobile pod, or a practice.
Most teams start small, with one engineer inside the app they already have. Some need a pod that takes the whole cross-platform surface off their plate. When the real ask is a finished app, not an added seat, we point you toward the practice instead.
- Team extension
One named engineer
A single Flutter specialist inside your direction and your reviews. The smallest commitment, and where most engagements begin.
- Delivery pods
A mobile pod
A pod with its own lead that owns the Flutter app end to end, both platforms included. You set priorities while the pod carries delivery.
- Mobile app development
The practice, not the person
Where shipping the whole app matters more than filling a seat, mobile app development takes on that delivery accountability instead.
06Straight answers
Asked before a Flutter hire is signed.
01What does a Flutter engineer actually do day to day?
Designs widget architecture and state management that scale, keeps rendering efficient as screens grow complex, and closes the platform-channel gaps a plugin doesn't already cover. The unglamorous majority of the work is making both platforms actually feel the same.
02Do you hire for a specific state-management approach?
Matched to your actual app. Architectural judgement about rebuilds and state transfers across Provider, Riverpod or Bloc, then the evaluation confirms familiarity with whichever your app runs.
03Can we run our own interviews as well?
Yes, the published tasks are built to be reused directly. Several clients now run the rebuild-performance exercise themselves in later hiring rounds.
04How fast can a Flutter engineer start?
A shortlist arrives within days from a bench evaluated continuously. Real start speed after that tracks your own repository and native-tooling access process.
05Who manages the engineer day to day?
Your leads own the roadmap and the release calendar. What we carry is the layer behind the engineer: continuity, payroll, replacement risk and the handoff work if plans shift.
06What if the engineer is not the right fit?
Bring it up early and the replacement is on us, no argument. The next engineer is given the specific reason it didn't work, so it rarely happens twice.
07Do your Flutter developers use AI coding tools?
Yes, openly. AI drafts widget scaffolding and test suites quickly; the engineer stays accountable for every state-management decision, platform-channel boundary and merge that reaches your app.
08How does pricing work for a hired Flutter engineer?
Expect the range shown in the bands above, with the shortlist confirming the specific figure. Billing runs monthly per engineer, there is no placement fee, and notice-period terms apply.
