What You'll Own :

• Own the application architecture, scalability, modularity, design patterns, and engineering standards.

• Build complex features, write production-grade Dart/Flutter code, review code, and develop reusable components.

• Optimize app startup, rendering, memory, network usage, responsiveness, and overall performance across devices.

• Improve application stability, troubleshoot production issues, conduct root-cause analysis, and reduce crashes and failures.

• Establish standards for state management, networking, security, caching, error handling, and automated testing.

• Resolve platform-specific issues and manage native integrations, plugins, permissions, notifications, and OS compatibility.

• Own reliable mobile builds and releases while improving automation, deployment pipelines, versioning, and rollback processes.

• Implement secure coding practices and protect authentication, sensitive data, local storage, and API communication.

• Guide mobile engineers through technical decisions, design and code reviews, mentoring, and engineering best practices.

• Drive refactoring, dependency modernization, technical-debt reduction, and improvements to engineering productivity.

• Partner with Product, Design, Backend, QA, Data, and Platform teams to align technical decisions with product goals and delivery timelines.

Who You Are :

• A hands-on engineer who takes end-to-end ownership of mobile technical outcomes.

• Comfortable making architectural decisions and evaluating engineering trade-offs.

• Strong at debugging complex issues and improving performance, reliability, and scalability.

• Able to mentor engineers and maintain high engineering standards without requiring formal people-management responsibility.

• Proactive about technical debt, continuous improvement, and cross-functional collaboration.

Required Qualifications :

• 6 - 8 years of software engineering experience, with significant production mobile development experience.

• Strong hands-on expertise in Flutter and Dart, including application architecture, widget lifecycle, rendering, state management, and asynchronous programming.

• Experience owning the architecture and technical direction of a production Flutter application.

• Strong understanding of Android and iOS development, REST APIs, networking, local storage, caching, background processing, notifications, and deep linking.

• Experience with application performance optimization, debugging, and production issue resolution.

• Experience writing unit, widget, and integration tests.

• Experience with Git, code reviews, CI/CD, and automated mobile builds and releases.

• Strong software design fundamentals, problem-solving skills, and communication abilities.

Nice to Have :

• Experience building and scaling consumer-facing mobile applications.

• Knowledge of native Android (Kotlin/Java) or iOS (Swift/Objective-C).

• Experience with payment, authentication, maps, location, analytics, or other third-party SDKs.

• Familiarity with Firebase, Crashlytics, mobile observability, and performance monitoring.

• Experience with feature flags, staged rollouts, A/B testing, and automated release tools such as Fastlane or GitHub Actions.

• Experience with modular Flutter applications and reusable component libraries.

• Experience in automotive, mobility, EV, payments, or consumer technology.

• Experience working in a high-growth startup environment.
