Principal Mobile Engineer, Platform - MetaMask
About the role
Consensys is the leading blockchain and web3 software company founded by Joe Lubin, CEO of Consensys and Co-Founder of Ethereum. Since 2014, Consensys has been at the forefront of innovation, pioneering technological developments within the web3 ecosystem.
Through our product suite, including the MetaMask platform, Infura, Linea, Diligence, and our NFT toolkit Phosphor, we have become the trusted collaborator for users, creators, and developers on their path to build and belong in the world they want to see.
About the Role
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
- 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).
