About the Role:
We're looking for a seasoned Senior Mobile Engineer (Flutter) who has built and scaled real-world mobile products and understands the craft behind delivering fast, reliable, and user-centric experiences. At HighLevel, you'll help shape a mobile platform used by hundreds of thousands of users across small and medium businesses, working on core feature development, cross-platform abstractions, performance optimizations, and our WYSIWYG mobile app customizer for white-label apps.
This role is ideal for an engineer who goes beyond implementation — someone who understands how mobile systems behave under the hood, cares deeply about performance and resource efficiency, and brings strong product intuition to every decision. You'll collaborate with product, design, and backend teams, guiding both what we build and how we build it. If you enjoy solving complex technical challenges, thinking like a product engineer, and influencing systems at scale, this is the place to make meaningful impact.
Qualifications
- Experienced in building and scaling production-grade Flutter applications with deep knowledge of rendering, widget lifecycle, state management, concurrency, and performance tuning.
- Strong native expertise in Android (Kotlin/Java) or iOS (Swift), including comfort with platform APIs, debugging tools, and architectural patterns.
- Proven ability to optimize for memory usage, CPU load, battery efficiency, networking, and storage to deliver smooth and resource-efficient mobile apps.
- Strong understanding of concurrency models (isolates, async/await, streams, coroutines, GCD) and ability to build responsive and resilient systems.
- Comfortable working with reactive architectures.
- Ability to design clear abstractions, write maintainable and idiomatic code, and consistently improve the codebase.
- Familiarity with other cross-platform technologies (React Native) or exposure to web/backend systems (Node/NestJS, Go, etc.) is a strong plus.
- Strong communication skills and a product-engineering mindset, with the ability to understand customer needs, challenge assumptions, and shape solutions.
- Collaborative approach with experience in Git, CI/CD workflows, code reviews, and cross-functional teamwork.
