• Proven experience (5+ years) in a senior software engineering role with a significant mobile component; possibly 10+ years in software engineering.


• Expertise in Swift, Kotlin, and ideally in Objective C and Java.


• Significant experience in adapting to and learning new software stacks and code bases.
