About the Role
We are seeking a Full-Stack Engineer with a 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.
