Parity Technologies builds core infrastructure for blockchains and Web 3.0 technologies. This means dealing with P2P networking, consensus algorithms, cryptography, databases, and decentralised applications. We strive to write the fastest, lightest, and safest core technology in Blockchain and write lots of open-source code. At Parity Technologies, we have built and launched live networks like Kusama and Polkadot atop the Substrate blockchain framework. We want to bring to these networks first-class end-to-end user experiences which tell a story of how easy it is to use these next-generation blockchains. For example, improving how users participate in network staking, how members of our governance systems present and vote on proposals, enabling simple integration of Substrate systems into web pages, improving how new users onboard into our ecosystem, and more… As the company rapidly grows, we seek a dedicated iOS Developer to join the Signer Team. The person will be responsible for our air-gapped wallet called Parity Signer- an iOS and Android app with a universal Rust backend, which is essentially a Ledger in the Substrate ecosystem. https://www.parity.io/technologies/signer/ With Parity Signer, people can easily keep their private keys secure and sign transactions. They can turn their old smartphone into a hardware wallet for Polkadot, Kusama, and other Substrate-based chains. All data is transmitted over the air via QR codes. Signer has a universal backend written in Rust for all cryptography-related operations. It utilizes hardware encryption (secure enclave) on devices where possible. The app interface is implemented on Swift UI and communicates with the backend using Mozilla's UniFFI. It's also open source: https://github.com/paritytech/parity-signer You will be responsible for the iOS version of Signer.
