Principal Mobile Engineer Platm MetaMask

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 Meta Mask 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.

Whether building a dapp, an NFT collection, a portfolio, or a better future, the instinct to build is universal. Consensys inspires and champions the builder instinct in everyone by making web3 universally easy to use and develop on.

Our mission is to unlock the collaborative power of communities by making the decentralized web universally easy to access, use, and build on.

You’ll get to work on the tools, infrastructure, and apps that scale these platforms to onboard one billion participants and 5 million developers. You’ll be constantly exposed to new concepts, ideas, and frameworks from your peers, and as you work on different projects—challenging you to stay at the top of your game. You’ll join a network of builders that reaches the edge of our ecosystem.

Consensys alumni have moved on to become tech entrepreneurs, CEOs, and team leads at tech companies.

Meta Mask's Wallet Platform organization owns the client platforms for the Meta Mask browser extension and mobile apps. The Mobile Platform team treats Meta Mask 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.

Meta Mask 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 Meta Mask app.

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

As a Principal Engineer, you will:

• Own mobile platform architecture
• Define and evolve the architecture of Meta Mask Mobile (React Native + native)
• 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 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 and 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
• 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 and 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 Meta Mask
• Lead design and architecture reviews for critical platform areas
• Help shape hiring and technical culture for a lean, senior, high-leverage Mobile Platform team
