Staff Software Engineer (Mobile), Bitkey

Job Description
Bitkey sits within the Proto organization. Proto's purpose is to accelerate the world’s transition to a more open economy by making products that increase access and independence for everyone. The first two initiatives we’ve identified that represent the biggest impact to this purpose are in the Bitcoin space with Bitcoin mining and Bitkey, a self custody Bitcoin wallet. While we’re starting there, we don’t believe the need for tools to increase one’s independence is limited to bitcoin or the financial space. One principle across everything we do in Proto is open development – show and tell. We develop products, you can read more about them at bitkey.Build and mining.Build.
We are growing our small cross-discipline engineering team and are looking for a mobile engineer who has experience architecting Kotlin Multiplatform solutions or deep experience architecting Kotlin-based Android solutions at scale with a strong interest in diving deep into Kotlin Multiplatform. We have blurred the lines of a traditional Android and iOS team by focusing on the right, single solution across multiple platforms in efforts to make it simple and easy to iterate on the Bitkey product. We’re looking for someone to help our team of passionate mobile engineers shape our multiplatform story in a scalable, sustainable, and secure way.
This role will also include deep feature development work in the Bitkey self-custody wallet with our existing team of mobile and server engineers. After all, the best way to help shape our architecture is to build in it!
You will:
Ship critical features in a non-custodial, hardware-enabled bitcoin wallet to a global audience
Collaborate with and help lead an experienced group of mobile engineers to evolve our multi-platform mobile system architecture, advance our testing capabilities and performance, and help iterate on and improve our mobile CI infrastructure
Improve our mobile release pipeline by increasing automation and improving reliability
Work closely with designers and product managers to build user experiences expanding the offerings of Bitkey
Work with a small team of engineers across our Mobile Application (KMP, Kotlin, Swift) and Rust backend on a team responsible for features from ideation through long-term maintenance
