About The Position

THE ROLE: We have three openings with the same title. Build, prototype, and scale next-generation mobile experiences by operating as an innovation engineer, not just a feature implementer. This role exists to transform ambiguous ideas into validated mobile solutions—balancing rapid experimentation with long-term platform integrity. You will help define what should be built, why it matters, and how it can scale across ecosystems. You will bring deep mobile expertise while working at the intersection of product discovery, platform evolution, and technical experimentation, crafting mobile strategy as much as execution. 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 contribute to discovery sprints, feasibility studies, and technical spikes● Challenge assumptions and propose alternative mobile experiences or architecturesPrototyping & 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 learningMobile 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 insightOperational 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

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
Experience 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)
Contributions to open-source, side projects, or experimental work
Experience with mobile database solutions (Core Data, Room, Realm, SQLite)
Understanding of mobile security guidelines and common vulnerabilities
Experience with mobile CI/CD tools (Fastlane, Jenkins, GitHub Actions)
Familiarity with cloud platforms (AWS, Azure, Google Cloud) for mobile backends
Experience with augmented reality (ARKit, ARCore) or other emerging mobile technologies
Understanding of app store submission and review processes

Nice To Haves

Master’s degree or equivalent experience with a demonstrated innovation portfolio (prototypes, experiments, published apps)
Platform-specific certifications (Apple Developer certification, Google Associate Android Developer), and relevant technology certifications are valuable
Outstanding portfolios showing sustained innovation impact may substitute for formal education.

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 contribute 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
