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.
CodeNinja is a Middle Eastern–American Software & AI company helping businesses build AI systems and learning architectures for mission-critical workloads.
With offices in Seattle, San Francisco, Riyadh, and Lahore, our work centers on enabling organizations to develop capabilities across workplaces and factory floors using both open-source and proprietary AI models, spanning generative and deterministic systems.
We believe most workplaces and factory floors are not ready for the post-AGI era of work. Our mission is to help enterprises reimagine how work itself is organized and executed so that human talent and automation not only coexist but thrive. We call this mission: “Reimagining Workplaces for Post-AGI Readiness.”
At the core of our approach is Hyper Tools, our integrated Platform + Services model, designed to accelerate the creation of AI applications and agents in complex domains. Hyper Tools reduces the generality of large models through reinforcement learning, rapid development workflows and purpose built synthetic and manual Data creation.
Our focus spans four core thrust areas:
Physical AI Systems – Building AI/ML systems for physical infrastructure. Some of the world’s leading chemical and energy companies rely on CodeNinja’s outcome-based, vendor-independent models to enhance operational efficiency and revenue.
Work AI – Developing agentic AI systems that transform workplace processes into adaptive, intelligent experiences.
Hyper Core – Enabling enterprises to build software and automation layers in-house instead of outsourcing to Software Services Vendors.
Global Capability & AI Centers – Partnering with universities and developer communities in South Asia and South America to build AI and research talent pipelines, helping global companies scale their capabilities sustainably.
Founded by 4 Engineers and incredible team of operators, CodeNinja is united by this mantra of " Inspiration and Innovation for every knowledge worker in the world"
