Mid Flutter Engineer

Mid Flutter Engineer (B2B Contract)

We are looking for a mid-level Flutter Engineer who can take ownership of mobile feature delivery within a product-driven environment. This role requires a balance between hands-on development, understanding of mobile architecture, and the ability to work independently within an experienced team.

About the project

You will join a product-focused team building and scaling a cross-platform mobile application used across multiple international markets.

• 100% Flutter-based application (no legacy, no migration)

• Contribute to a modular and scalable architecture

• Integrate backend services using GraphQL and REST APIs

• Ensure code quality through unit, widget, and end-to-end testing

• Collaborate closely with product managers, designers, and engineers

• Participate in the full development lifecycle: design, implementation, release, and monitoring

• Debug and optimize app performance (rendering, networking, stability)

• Take ownership of delivered features and propose improvements where relevant

Requirements:

• Solid commercial experience with Flutter (Dart) in production environments

• Experience working on live mobile applications (App Store / Google Play)

• Ability to work independently within a team of experienced engineers

• Good understanding of mobile architecture patterns (e.g. BLoC, Provider, Riverpod, Clean Architecture, modularization)

• Experience integrating APIs (preferably GraphQL, plus REST)

• Practical experience with testing (unit, widget, or E2E)

Nice to have:

• Experience with mobile CI/CD pipelines

• Familiarity with monitoring and analytics tools

• Exposure to end-to-end testing frameworks

• Experience working in product-oriented environments
