About the Mobile Platform Team

MetaMask’s Wallet Platform organization owns the client platforms for the MetaMask browser extension and mobile apps. The Mobile Platform team treats MetaMask Mobile as a platform: we enable all feature teams to ship high‑quality experiences faster by providing a secure, stable, high‑performance foundation with excellent developer experience and automated operations.

MetaMask Mobile (iOS & Android) is built primarily on React Native, with native code where it matters. As a Principal Mobile Engineer, you’ll be the most senior hands‑on technical leader focused on mobile: setting architecture, defining standards, and driving cross‑team initiatives that shape the future of our mobile platform and MetaMask app.

You’ll work closely with engineers across MetaMask, not just within Mobile Platform, to ensure our mobile apps performance and stability scale with our users, features, and the broader Web3 ecosystem.

What you’ll do

As a Principal Engineer, you will:

• Own mobile platform architecture
  • Define and evolve the architecture of MetaMask Mobile (React Native + native), leaning into performance by tightly integrating with backend services and optimizing app–backend interactions holistically rather than in isolation.
  • Make key tradeoffs between JS/TS, RN, and native to balance performance, reliability, and iteration speed.
  • Design and steward core platform systems (e.g., OTA, analytics foundations, data/persistence, auth, VPN/geolocation primitives).
  • Lead design and architecture reviews for critical platform areas.
• Lead high‑impact, cross‑team initiatives
  • Drive large upgrades and migrations (React Native, navigation, foundational libraries).
  • Lead structural performance and stability work: startup time, crash rate, ANRs, jank, memory usage, bundle size.
  • Break large efforts into incremental, shippable milestones with clear impact.
• Elevate developer experience & automation
  • Improve tooling, local dev ergonomics, build/test pipelines, and release workflows for all mobile engineers.
  • Establish clear patterns for navigation, state management, and platform primitives to reduce cognitive load.
  • Push towards “push‑button” releases and reduced operational toil via automation.
  • Own and continuously improve the mobile SDLC and lifecycle, including CI, testing, and release workflows.
• Build an AI‑enabled platform
  • Integrate AI/LLMs into workflows to scaffold code, enforce patterns, and improve testing and feedback loops.
  • Help define how tickets and platform patterns leverage AI safely and effectively.
• Drive app health & performance culture
  • Define and evolve metrics and dashboards for performance, stability, and efficiency.
  • Provide tools and guidance so feature teams can self‑diagnose and own regressions.
  • Champion shared accountability for app health across all teams contributing to mobile.
• Multiply impact through leadership
  • Mentor Senior/Staff engineers and influence technical direction across Wallet Platform and MetaMask.
  • Help shape hiring and technical culture for a lean, senior, high‑leverage Mobile Platform team.

Would be great if you brought this to the role

• Experience
  • ~10+ years building and scaling mobile apps, including ownership of large, production React Native or hybrid mobile platforms.
    Prior Staff/Principal‑level impact: leading complex, cross‑team technical initiatives.
• Technical depth
  • Deep expertise with React Native in production: architecture, performance, debugging, bridging.
  • Solid experience with native iOS (Swift/SwiftUI) and/or Android (Kotlin/Jetpack), including native modules and performance tuning.
  • Strong understanding of mobile CI/CD, release engineering, and OTA systems.
• Platform & systems mindset
  • Track record building internal platforms, shared libraries, or tooling for other engineers.
  • Comfort operating in ambiguity and designing durable, reusable solutions.
  • Strong architecture and communication skills; able to align diverse stakeholders.
• Leadership & mentorship
  • Proven ability to influence without authority, set technical direction, and raise the engineering bar.
  • Experience mentoring senior engineers and shaping technical culture.
• AI‑curious / AI‑pragmatic
  • Experience or strong interest in using AI/LLMs to improve developer productivity and code quality.

Bonus Points

• Experience with crypto / Web3, wallets, fintech, or other security‑sensitive apps.
• Contributions to open‑source in React Native, mobile, performance, or tooling.
• Experience optimizing apps for emerging markets or low‑end devices.
• Background in fully remote, globally distributed teams.
