Full Stack Flutter Developer

About the role

We are seeking a full-stack engineer with strong expertise in Flutter to join a fast-growing startup building digital solutions for the construction industry. While your primary superpower will be driving mobile app development using Flutter, you will also play a key role in building, maintaining, and integrating the backend services that power our mobile experiences. This is a hands-on role for a versatile engineer who enjoys building scalable, end-to-end features in a fast-paced, agile environment.

Key responsibilities

• Frontend mobile development: Design, build, and maintain cross-platform mobile applications using Flutter/Dart, translating complex UI/UX designs into high-quality, responsive interfaces.
• Backend architecture & integration: Develop, optimize, and maintain scalable backend services, databases, and server-side logic to support the mobile application.
• API management: Design and implement robust RESTful APIs, WebSockets, or GraphQL endpoints, ensuring smooth data synchronization between the frontend and backend.
• Performance optimization: Debug, profile, and optimize end-to-end application performance—addressing both mobile UI rendering bottlenecks and backend database query latency.
• Clean code & architecture: Maintain clean, scalable, and well-documented architectural patterns across the entire technical stack.
• Startup collaboration: Work closely with product owners, designers, and the broader engineering team to contribute to architectural decisions as our product scales.

Requirements

• Core mobile expertise: 3–5 years of hands-on experience with Flutter & Dart, with a proven track record of shipping production-ready mobile apps to the App Store and Google Play.
• Robust backend experience: Solid experience building server-side applications using modern backend technologies (e.g., Node.js, Python/Django, Go, or .NET) and managing relational/non-relational databases (PostgreSQL, MongoDB, etc.).
• State management & architecture: Deep understanding of Flutter state management solutions (Bloc, Riverpod, or Provider) and solid architectural patterns (Clean Architecture, MVVM).
• System integration: Strong proficiency in REST API integration, authentication protocols (OAuth2, JWT), and third-party SDK integrations.
• Industry context: Prior experience building software for construction, real estate, PropTech, or field-services industries is a strong plus.
• Mindset & communication: Comfortable navigating a fast-paced startup environment with evolving scopes. Strong English communication skills (written and verbal) are essential.

Nice to have

• Experience with cloud infrastructure (AWS, Azure, or GCP) and serverless architectures.
• Familiarity with mobile CI/CD pipelines (Codemagic, Fastlane, GitHub Actions) and automated testing frameworks.
• Background in native Android (Kotlin) or iOS (Swift) development.
