> CodeNinja · Riyadh, Saudi Arabia · — · Posted 2026-07-05

**Workplace:** on_site

**Department:** Professional Services

## Description

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.
