Flow is a layer one blockchain designed from the ground up as a platform for a new generation of Web3 apps, games, and the digital assets that power them. Flow is home today to millions of users and apps from top tier creators including Genies, Cryptoys, Doodles, and Dapper Labs (NBA, NFL, Disney) as well as industry leaders such as Mattel (Barbie, Hot Wheels), LiveNation / Ticketmaster, and many more.

2025 will be Flow’s biggest year yet. To prepare, Flow recently launched Flow Wallet - a new wallet built from the ground up for Flow. Flow Wallet aims to set the new standard for wallets across all of Web3 by leveraging what’s uniquely possible with Flow’s account abstraction, smart contract programming language Cadence, and mainstream consumer audience.

Flow’s mission is to take Web3 mainstream, and Flow Wallet is a big piece of the puzzle for how we’ll get there. We believe it’s unacceptable for users to have to tolerate the possibility of losing their keys, assets or accounts, have to set up their wallets using complex seed phrases, or worry about things like gas fees. At the end of the day, users just want to have fun, and feel safe to explore and experience what Web3 makes possible for them.

As a Staff Mobile Engineer, you’ll get to pave the way forward for the Web3 industry at large, and you’ll love that you’ll be empowered to solve the frustrations you have with Web3 wallets first hand.

About the Role

Your mission, should you choose to accept, is to level-up Flow Wallet’s development on iOS and/or Android. You’ll get to dive into building awesome new features like account recovery, human readable transactions, secure enclave support, passkey integration and many many more. You’ll be on the front lines of how Web3 will go mainstream, and solve major industry problems like user onboarding to crypto, empowering users to truly own their assets with self-custody, and drive mainstream adoption to Web3 apps.

Here's what your scope will include:

Building industry leading wallet features: Flow Wallet is currently working towards becoming the world's first multi-VM wallet, supporting both the Cadence and EVM ecosystems on Flow. You’ll be responsible for thinking big and pioneering first of their kind initiatives in Web3.

You’ll be responsible for the security of users and their assets secured by Flow Wallet.
Product-minded software engineering: Flow’s next challenges require engineers who love bridging the gap between product and engineering. The complexities in delivering an industry leading wallet require engineers on Flow Wallet to think through how their software impacts our users, and be mindful of how what we build can impact them. You’ll be responsible for translating product requirements into user value, and understanding how to best get there through the software you create.
Self-driven development: Flow believes experienced senior engineers can drive business initiatives from start to finish, work autonomously and use their intuition from experience to guide their success. You’ll be responsible for driving your own product initiatives, and will be given trust and room to make them a success.
Delivering mainstream-ready software quality: Flow is gearing up to support not only it’s existing ecosystem of Cadence developers, but also the rest of the Web3 ecosystem of EVM builders.
