As a Staff Mobile Engineer (Tech Lead), you will be a key contributor to the Engineering team, responsible for building and maintaining client-side applications and backend systems. You will define and drive the long-term technical vision and architecture for Gametime's mobile platform, explore AI-powered capabilities, and mentor engineers at all levels. Enjoy benefits such as health coverage, equity, flexible PTO, and a monthly Gametime credit.

• Contribuer de manière significative à l'équipe d'ingénierie en construisant et en maintenant des applications client et des systèmes backend.
• Définir et conduire la vision technique à long terme et l'architecture de la plateforme mobile de Gametime, en explorant et en championnant les capacités alimentées par l'IA.
• Mentorer et élever les ingénieurs à tous les niveaux grâce à des revues de code, des conseils architecturaux et un leadership technique.
• React Native Mastery: Deep, production-proven expertise in React Native, including the New Architecture (Fabric/TurboModules), bridging native modules, and cross-platform parity strategies
• TypeScript: Expert-level TypeScript usage for type safety, scalability, and maintainable codebases across large mobile teams
• State Management & Architecture: Deep experience with scalable state management patterns (Redux, Zustand, Jotai, or equivalent) and mobile-specific architectural patterns (clean architecture, modular monorepos, etc.)
• Mobile Observability: Strong command of mobile crash reporting, performance monitoring, and analytics tooling (e.g., Firebase, Datadog, Sentry, Amplitude)
• Cloud & API Integration: Proficient with RESTful and GraphQL API design and consumption patterns, and cloud infrastructure as it relates to mobile backends (AWS, GCP, or Azure)
• App Distribution & Release Engineering: Deep knowledge of App Store and Google Play release processes, phased rollouts, feature flags, and OTA update strategies (e.g., EAS Update). Experienced designing mobile CI/CD pipelines using tools like Bitrise, GitHub Actions, and Fastlane
• AI Tooling & Integration: Experienced leveraging AI for code generation and evangelizing best practices for integrating it into the development workflow. Familiar with shipping AI/ML-powered features in mobile apps — on-device models, LLM-backed experiences, and recommendation systems
• Testing: Strong culture of testing — unit, integration, and end-to-end testing for mobile using tools like Jest, Detox, or Maestro
• Mobile Platform Expertise: Strong understanding of both iOS (Swift/Objective-C) and Android (Kotlin/Java) native layers — comfortable diving into native code when React Native abstractions aren't sufficient
• Performance Engineering: Expert at diagnosing and resolving React Native and native performance bottlenecks — JS thread, UI thread, bridge overhead, memory, startup time, and render optimization
• Mentorship: Actively mentors engineers and uplifts team performance through coaching, feedback, and hands-on pairing
• Cross-Functional Collaboration: Trusted partner to Product, Design, Data, and Engineering peers — able to translate technical constraints into business context and vice versa
• Strategic Influence: Helps shape technical direction, roadmap priorities, and engineering best practices at the organizational level
• Technical Vision: Defines technical direction for the mobile platform with clarity, conviction, and organizational buy-in
• Domain Expertise/Ownership: Deep understanding of the mobile product surface area with the ability to lead initiatives from concept through production at scale
• Org-Wide Influence: Shapes engineering practices, architectural decisions, and tooling choices that extend beyond the mobile team to the broader engineering organization
• Project Leadership: Independently manages the full lifecycle of complex, multi-team projects with competing priorities and stakeholders
• Experience: 10+ years in software engineering, with 5+ years of hands-on experience building and scaling production mobile applications, including significant time in React Native
• Education: Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience)
