Staff iOS Engineer

Radar•San Diego, NY

About The Position

RADAR is hiring a Staff iOS Engineer to shape the company’s mobile and cross-platform technical strategy and influence engineering direction beyond the iOS team. The company is rebuilding its mobile apps, and this senior individual contributor will provide technical leadership without formal management duties. The role calls for significant autonomy, hands-on engineering, and collaboration with product, design, Android, platform, and backend leaders. The engineer will define long-term mobile architecture, help lead cross-platform strategy—including shared code and Kotlin Multiplatform adoption—and guide major initiatives from concept through measurable outcomes. They will build complex, high-leverage parts of the iOS codebase in Swift and SwiftUI, establish engineering standards, and mentor Staff and Senior engineers. The role also includes planning a smooth, low-risk migration of existing customers from legacy apps to the rebuilt app while continuing to support and improve legacy products. RADAR describes itself as a retail technology company building a hardware-enabled SaaS platform that uses overhead sensors, software, and AI-powered analytics to locate products in stores. Its platform is deployed in more than 1,500 stores and processes tens of billions of real-world events daily. The expected base salary range is $172,000–$250,000. Individual pay depends on work location and factors including relevant skills, experience, education, or training. The position is also eligible for equity and the benefits listed below.
