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.
