Staff Mobile Engineer, Tech Lead

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Mobile Engineer, Tech Lead based in United States.

This is a senior individual contributor role responsible for shaping the long-term technical direction of a high-scale mobile platform serving more than one million users each week.

You will lead architecture and engineering strategy across iOS and Android through React Native, with a strong focus on performance, reliability, and scalability.

The role combines deep hands-on engineering with cross-functional technical leadership across Engineering, Product, Design, Data, and business teams.

You will help advance AI adoption in mobile development, including agentic coding tools, on-device intelligence, and AI-powered product experiences.

You will establish engineering standards around architecture, testing, observability, CI/CD, release quality, and mobile development practices.

As a technical leader, you will mentor engineers, influence organization-wide decisions, and lead complex initiatives that span multiple teams.

The environment values ownership, experimentation, operational excellence, collaboration, and continuous improvement while giving engineers significant influence over the evolution of the platform.

Accountabilities:

• Define and drive the long-term technical vision, architecture, and infrastructure strategy for the mobile platform across iOS and Android using React Native.
• Own the end-to-end technical strategy for the mobile application, covering architecture patterns, platform infrastructure, performance, reliability, and release engineering.
• Evaluate and champion AI-powered capabilities within mobile development, including agentic coding tools, on-device intelligence, and AI-driven personalization.
• Lead complex cross-functional initiatives spanning mobile, backend, product, design, and data teams while maintaining alignment on priorities and execution.
• Establish and promote engineering standards for code quality, testing, observability, architecture, and mobile-specific development practices.
• Drive improvements in application performance, reliability, and release quality through CI/CD, crash monitoring, progressive rollouts, and continuous optimization.
• Identify and eliminate platform-level bottlenecks that affect engineering velocity or user experience.
• Partner with Product and Design to translate business objectives into scalable, technically sound mobile solutions and roadmap priorities.
• Mentor engineers across experience levels through code reviews, architectural guidance, hands-on pairing, coaching, and technical thought leadership.
• Promote engineering excellence through technical talks, documentation, best-practice sharing, and collaborative problem solving.
• Influence broader engineering architecture, tooling, and development practices beyond the mobile organization.
• Lead initiatives from concept through production while balancing technical complexity, business priorities, and competing stakeholder needs.

Requirements:

• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• 10+ years of software engineering experience, including 5+ years building and scaling production mobile applications with significant React Native experience.
• Deep, production-proven expertise in React Native, including the New Architecture, Fabric, TurboModules, native module bridging, and cross-platform parity strategies.
• Strong expertise with TypeScript and scalable state management approaches such as Redux, Zustand, Jotai, or equivalent technologies.
• Strong understanding of both iOS native development with Swift or Objective-C and Android development with Kotlin or Java, with the ability to work directly in native code when required.
• Deep experience with mobile architecture patterns such as clean architecture and modular monorepos.
• Expert knowledge of mobile performance optimization, including JavaScript and UI threads, bridge overhead, memory usage, startup time, and rendering performance.
• Strong experience with mobile observability, crash reporting, performance monitoring, and analytics platforms such as Firebase, Datadog, Sentry, or Amplitude.
• Deep knowledge of App Store and Google Play distribution, phased rollouts, feature flags, OTA updates, and mobile CI/CD using tools such as Bitrise, GitHub Actions, or Fastlane.
• Strong testing experience across unit, integration, and end-to-end mobile testing using technologies such as Jest, Detox, or Maestro.
• Proficiency with RESTful and GraphQL APIs and familiarity with cloud infrastructure supporting mobile backends, including AWS, GCP, or Azure.
• Experience using AI for software development and familiarity with AI/ML-powered mobile capabilities such as on-device models, LLM-backed experiences, and recommendation systems.
• Ability to define technical direction, build organizational alignment, and influence architectural decisions beyond the immediate mobile team.
• Strong project leadership skills, with the ability to independently manage complex, multi-team initiatives and competing priorities.
• Excellent communication and collaboration skills with Product, Design, Data, Engineering, and business stakeholders.
• Demonstrated ability to mentor engineers, raise technical standards, and lead through influence rather than formal authority.

Benefits:

• U.S. salary range of $213,554-$251,240 USD.
• Competitive salary and equity package.
• Flexible PTO.
• Monthly credits for live events, valued at up to $1,200 annually.
• Medical, dental, and vision insurance.
• Life insurance and disability benefits.
• Family-forming benefits through fertility support programs.
• 401(k), HSA, and pre-tax savings programs.
• Company off-sites and team meet-ups.
• Wellness programs.
• Tenure recognition.
• Inclusive environment focused on collaboration, diverse perspectives, and professional growth.
