Svitla Systems Inc. is looking for a Senior Kotlin Engineer for a full-time position (40 hours per week) in Poland. Our client is the world’s leading cryptocurrency wallet company, which is designed to provide users with access to Web3, facilitating online payments and the exchange of digital assets through blockchain. It supports millions of assets across 100+ blockchains, including major chains like Bitcoin, Ethereum, BNB Smart Chain, Cosmos, and Polkadot. The application combines a web-based browser and a complete security audited system to send, receive, and store digital assets as well as synchronize with tokens issued on the Ethereum blockchain, enabling users to exchange bitcoins, currencies, and assets in real-time, interact with any decentralized application and have complete control of their Ethereum-based collectibles. Over 150+ million users trust this California-based company. 

We’re seeking experienced engineers who are passionate about building amazing products to join the Kotlin multiplatform team. This team creates and maintains a shared business logic layer across Android, iOS, and web apps. They’re constructing the SDK that reacts to user input and dictates what the UI displays on millions of devices. Currently, the KMM SDK integrates the business logic of blockchain interactions. They are expanding it to encompass even more of the app’s functionality. While they apply the MVI pattern, the views reside outside the KMM codebase. They believe that the “native” code should handle UI.
