Sr. Flutter Developer
About the position
THE ROLE: Build and scale next-generation mobile experiences by operating as an innovation engineer, not just a feature implementer. In this role, you’ll turn ambiguous ideas into validated, high-impact mobile solutions — balancing rapid experimentation with long-term platform stability and scalability. You’ll play a key role in shaping what gets built, why it matters, and how it can scale across mobile ecosystems. Working at the intersection of product discovery, platform evolution, and technical experimentation, you’ll apply deep mobile expertise to both strategy and execution — influencing mobile direction as much as you ship code. This is a hands-on role for builders who thrive in uncertainty, enjoy early-stage problem-solving, and want to leave a lasting mark on mobile platforms. This is not a traditional mobile delivery role. You will: ● Work in high-ambiguity environments ● Build prototypes before roadmaps ● Validate assumptions through experiments, data, and learning ● Help transition validated concepts into scalable, production-grade systems HOW YOU WOULD CONTRIBUTE: Discovery, Framing & Experimentation ● Partner with product, build, data, and business collaborators to frame problems, not just implement requirements ● Translate loosely defined ideas into hypotheses, experiments, and technical prototypes ● Lead or chip in to discovery sprints, feasibility studies, and technical spikes ● Challenge assumptions and propose alternative mobile experiences or architectures Prototyping & Validation ● Build rapid prototypes (throwaway and evolutionary) to test user value and technical feasibility ● Instrument prototypes with analytics to measure adoption, performance, and learning outcomes ● Run controlled experiments (feature flags, pilots, A/B tests) where appropriate ● Make informed tradeoffs between speed, quality, scalability, and learning Mobile Architecture & Platform Thinking ● Build native and cross-platform mobile solutions with platform and ecosystem thinking ● Influence mobile architecture decisions, frameworks, SDKs, and integration patterns ● Balance innovation velocity with long-term maintainability and platform evolution ● Collaborate on API contracts, data models, and service boundaries Engineering Excellence ● Write clean, efficient, and maintainable mobile code aligned with platform guidelines ● Implement secure, performant, and accessible user experiences ● Optimize performance across memory, battery, startup time, and responsiveness ● Apply mobile security guidelines, including authentication, encryption, and data protection Teamwork & Influence ● Collaborate closely with UX, backend, data, and product teams to build cohesive solutions ● Provide technical mentorship and architectural guidance to mobile engineers ● Communicate sophisticated technical ideas clearly to non-technical collaborators ● Influence direction through prototypes, evidence, and technical insight Operational Enablement ● Advise on mobile DevOps practices, including CI/CD, automated testing, and release strategies ● Support transition of validated concepts from innovation into scaled delivery teams Document architecture, experiments, findings, and technical decisions
Responsibilities
• Partner with product, build, data, and business collaborators to frame problems, not just implement requirements
• Translate loosely defined ideas into hypotheses, experiments, and technical prototypes
• Lead or chip in to discovery sprints, feasibility studies, and technical spikes
• Challenge assumptions and propose alternative mobile experiences or architectures
• Build rapid prototypes (throwaway and evolutionary) to test user value and technical feasibility
• Instrument prototypes with analytics to measure adoption, performance, and learning outcomes
• Run controlled experiments (feature flags, pilots, A/B tests) where appropriate
• Make informed tradeoffs between speed, quality, scalability, and learning
• Build native and cross-platform mobile solutions with platform and ecosystem thinking
• Influence mobile architecture decisions, frameworks, SDKs, and integration patterns
• Balance innovation velocity with long-term maintainability and platform evolution
• Collaborate on API contracts, data models, and service boundaries
• Write clean, efficient, and maintainable mobile code aligned with platform guidelines
• Implement secure, performant, and accessible user experiences
• Optimize performance across memory, battery, startup time, and responsiveness
• Apply mobile security guidelines, including authentication, encryption, and data protection
• Collaborate closely with UX, backend, data, and product teams to build cohesive solutions
• Provide technical mentorship and architectural guidance to mobile engineers
• Communicate sophisticated technical ideas clearly to non-technical collaborators
• Influence direction through prototypes, evidence, and technical insight
• Advise on mobile DevOps practices, including CI/CD, automated testing, and release strategies
• Support transition of validated concepts from innovation into scaled delivery teams
• Document architecture, experiments, findings, and technical decisions
Requirements
• 5+ years of professional mobile development experience; experience working with diverse technology stacks and multiple projects preferred
• Proven experience across both exploration (early-stage) and exploitation (scaled delivery) preferred
• Native mobile development (Swift/SwiftUI for iOS and/or Kotlin for Android)
• Cross-platform development frameworks (React Native, Flutter, or similar)
• Mobile application architecture and design patterns (MVVM, MVC, Clean Architecture)
• API integration, mobile networking, and data synchronization
• Lifecycle management, memory management, diagnostics, and performance optimization
• Proven track record to work effectively with incomplete or evolving requirements
• Strong problem-framing and systems-thinking skills
• Experience building prototypes or proof-of-concepts—not just production features
• Curious approach with a bias toward experimentation and learning
• Ability to articulate why a solution works, not just how it’s built
• Proven track record of delivering production mobile applications with high quality and performance
• Deep understanding of iOS and Android platform capabilities, limitations, and guidelines
• Familiarity with mobile development tools and IDEs (Xcode, Android Studio)
• Strong problem-solving skills for complex technical challenges
• Ability to communicate technical concepts clearly to non-technical collaborators
• Mobile analytics (such as Firebase, Crashlytics), experimentation, and observability tooling
• Experience with feature flags, phased rollouts, or experimentation platforms
• Exposure to emerging mobile technologies (AI-enabled UX, AR, sensors, wearables)
• Experience with mobile database solutions (Core Data, Room, Realm, SQLite)
• Understanding of mobile security protocols and common vulnerabilities
• Familiarity with mobile CI/CD tools (Fastlane, Jenkins, GitHub Actions)
• Familiarity with cloud platforms (AWS, Azure, Google Cloud) for mobile backends
• Understanding of app store submission and review processes
• Minimum: Bachelor’s degree in Computer Science, Software Engineering, or equivalent experience
Nice-to-haves
• Contributions to open-source, side projects, or experimental work
• Experience with augmented reality (ARKit, ARCore) or other developing mobile platforms
• Preferred: Master’s degree or equivalent experience with a demonstrated innovation portfolio (prototypes, experiments, published apps)
• Certifications: Platform-specific certifications (Apple Developer certification, Google Associate Android Developer), and relevant technology certifications are valuable
• Equivalent Experience: Outstanding portfolios showing sustained innovation impact may substitute for formal education.
Benefits
• Herbalife offers a variety of benefits to eligible employees in the U.S. (limited to the 50 States and the District of Columbia), which includes Group Health Programs, other Voluntary Benefit Programs, and Paid Time Off.
• Group Health Programs include Medical, Dental, Vision, Health Savings Account (HSA), Flexible Spending Accounts (FSA), Basic Life/AD&D Short-Term and Long-Term Disability, and an Employee Assistance Program (EAP).
• Other Voluntary Benefit Programs include a 401(k) plan, Wellness Incentive Program, Employee Stock Purchase Plan (ESPP), Supplemental Life/Critical Illness/Hospitalization/Accident Insurance, and Pet Insurance.
• Paid time off includes Company-observed U.S. Holidays, Floating Holidays, Vacation, Sick Time, a Volunteer Program, Paid Maternity and Paternity Leave, Bereavement Leave, Personal Leave and time off for voting.
