About The Role We are looking for a hands-on Senior Mobile Full Stack Engineer who has deeply mastered both backend systems and native mobile development. You will take end-to-end ownership of critical production features—from designing high-performance Go microservices and data pipelines to crafting slick native mobile experiences. This is not a generalist role where mobile or backend is an afterthought. We need someone who has run backend services at scale and independently shipped native iOS or Android apps to production. The backend for this project is built in Go. Go experience is a plus, not a requirement: strong backend engineers who haven’t used it yet will pick it up on the job.

Native Mobile Engineering: Develop and maintain mobile features using modern native frameworks (Swift/SwiftUI or Kotlin/Jetpack Compose) and push updates to the App Store or Google Play. Technical Communication: Write clear Architecture Decision Records (ADRs), system design specs, and deliver thorough, actionable code reviews. You have 6+ years of professional experience building production software. 6+ years of production backend experience in Go, Java, Kotlin, Python, Rust, Node/TypeScript, Scala, C++ or a similar language, used as your primary backend language (not just as a secondary or…
