Flutter Mobile Developer Vacancy – Remote Contract Role
This Flutter Mobile Developer vacancy is an open remote contract role at SEOSERVICES1 for building and maintaining cross-platform iOS and Android applications with Flutter and Dart. The position is remote-first and contract-based, focused on production apps where stability, speed, and clean architecture matter.
SEOSERVICES1 is hiring a developer who can take ownership of mobile features end to end — from app structure and API integration to testing, release, and performance tuning. If you have shipped real Flutter apps to the App Store and Google Play and work well independently, this vacancy describes the scope, expectations, and application steps.
What Is This Flutter Mobile Developer Vacancy?
This is a remote, contract-based Flutter developer role centered on production-grade cross-platform mobile apps for iOS and Android. The core entities are SEOSERVICES1 as the hiring company, the contract developer as the contributor, and Flutter with Dart as the technical foundation.
The engagement is structured as a contract, not salaried in-house employment. Work is remote, with async communication and sprint-based delivery. The focus is mobile engineering — architecture, user interface implementation, integrations, and store releases — rather than marketing, SEO delivery, or general web development.
For context: Flutter is Google’s open-source UI toolkit for building natively compiled apps from a single Dart codebase. Dart is the programming language used with Flutter. Cross-platform here means one codebase targeting both iOS and Android.
What Will You Build and Own in This Role?
You will design, build, and maintain Flutter applications through the full mobile lifecycle, from architecture to App Store and Google Play release. Ownership includes code quality, performance, and reliable delivery.
Key areas of responsibility include:
- Cross-platform feature development: Build and update iOS and Android features using Flutter and Dart, with attention to layout accuracy and platform behavior.
- App architecture: Structure code for maintainability with clear separation of UI, business logic, and data layers.
- Performance tuning: Identify slow frames, excess rebuilds, large app size, or slow startup, and apply practical fixes to keep interaction smooth.
- Integration work: Connect apps to RESTful APIs, real-time sources such as WebSockets where needed, and third-party SDKs.
- Build and release management: Maintain automated builds and handle deployment steps for TestFlight, App Store Connect, and Google Play Console, including use of tools such as GitHub Actions, Codemagic, or Fastlane.
- Quality and maintenance: Diagnose crashes, fix root causes, and keep dependencies and release pipelines in working order.
Continuous Integration / Continuous Delivery (CI/CD) refers to automated build, test, and release workflows that reduce manual release errors.
What Skills and Experience Are Required?
Applicants need 3–5+ years of mobile development experience, including at least 2+ years shipping production Flutter apps with Dart. Production-level means apps actually released to users, not tutorials or prototypes alone.
The table below separates must-have qualifications from helpful extras.
| Area | Required for this vacancy | Preferred or helpful plus |
|---|---|---|
| Flutter and Dart experience | 3–5+ years in mobile, with 2+ years building released Flutter apps; solid async Dart, null safety, and package management | Contributions to open-source Flutter packages, pub.dev releases, or public GitHub samples |
| Architecture and state | Working knowledge of clean architecture and one or more state approaches such as BLoC, Riverpod, or Provider | Experience comparing trade-offs between BLoC vs. Riverpod in larger codebases |
| UI implementation | Ability to implement detailed layouts, navigation, and animations with Flutter’s rendering system | Motion design experience and accessibility-aware layouts |
| Data and backend | RESTful API integration, JSON handling, error states, caching, and secure storage practices | Hands-on work with Firebase, Supabase, push notifications, or real-time sync |
| Release engineering | Experience preparing iOS and Android builds and managing store submissions with CI/CD | Direct use of Codemagic, GitHub Actions, Fastlane, code signing, and staged rollouts |
| Native familiarity | Able to read platform docs and handle permissions, deep links, and SDK differences | Working knowledge of Swift and/or Kotlin for bridges and platform channels |
How do state management patterns differ? BLoC (Business Logic Component) separates events from states using streams, which suits larger teams and predictable testing. Riverpod offers compile-safe dependency management with less boilerplate. Provider is simpler and often sufficient for smaller apps but can become harder to scale without discipline.
How Is Success Measured in This Role?
Success is measured by app stability, rendering performance, and predictable delivery within sprint cycles. Expectations are practical, not perfection on day one.
- Stability: Low crash rate, high share of crash-free sessions, and timely fixes for production issues with clear root-cause notes.
- Performance: Smooth scrolling and transitions, commonly targeting 60 frames per second (FPS), plus attention to startup time and install size.
- Delivery: Complete sprint commitments reliably, with readable code, basic tests where appropriate, and clear pull-request descriptions.
- Collaboration: Explain technical limits and options in plain language so designers, managers, and stakeholders can make decisions.
Trade-off to expect: cross-platform speed comes with platform-specific edge cases. Camera, permissions, background tasks, and store review rules still require iOS- and Android-specific testing.
Who Should Apply — and Who Should Not?
This role fits autonomous, remote-ready Flutter developers who communicate clearly and take ownership; it is not a fit for beginners or developers seeking only on-site work.
You are likely a good fit if you:
- Have released and maintained Flutter apps used by real customers
- Are comfortable working independently in a remote-first contract setup
- Write structured, reviewable code and document decisions
- Can discuss performance, architecture, and release trade-offs without jargon
- Respond to bugs systematically and verify fixes before closing
This vacancy is likely not a fit if you:
- Have less than 2 years of hands-on Flutter production experience
- Prefer highly supervised tasks or fixed-hour on-site work
- Work only in native Swift/Kotlin without interest in Dart and Flutter
- Cannot participate in remote sprint planning, reviews, and async updates
SEOSERVICES1 is an equal opportunity employer committed to an inclusive work environment. Eligibility, contracting terms, and work authorization depend on individual circumstances and applicable regulations, which require qualified review and are not legal advice in this listing.
How Do You Apply for This Flutter Mobile Developer Vacancy?
To apply, submit your resume, portfolio or code links, and a short note on your preferred state management approach using the apply-by-email option for this listing. Applications without code evidence are harder to evaluate.
Include these three items:
1. Resume: Highlight mobile years, Flutter years, released apps, and your role on each app. 2. Code evidence: Links to App Store / Google Play listings, portfolio, GitHub, or pub.dev profile. Note what you personally built. 3. Short technical note: Name your preferred state pattern — for example, BLoC, Riverpod, or Provider — and explain in 3–5 sentences when you would choose it and why.
What happens next: relevant applications are reviewed for production Flutter depth, architecture judgment, and remote communication fit. Keep your links live and your contact details current so your work can be verified.
