ABOUT THE JOB

We’re looking for a Staff iOS Engineer to shape Radar’s mobile and cross-platform technical strategy and influence engineering direction well beyond the iOS team. We’re redesigning and rebuilding our mobile apps from the ground up, and you’ll be the technical leader shaping it. This is a senior individual contributor role with no formal management duties. You’ll lead through deep technical expertise, sound judgment, and influence. You’ll work with significant autonomy to set long-term architecture, drive innovation, and guide major cross-functional initiatives with product, design, Android, platform, and backend leaders. You’ll stay hands-on in the code while multiplying the impact of engineers across the organization.

Responsibilities:

• Define the multi-year mobile architecture and technical strategy.
• Co-lead cross-platform strategy, including shared code and Kotlin Multiplatform adoption, in partnership with Android and backend leaders.
• Drive innovation by finding new technical bets and platform capabilities that open up product opportunities.
• Guide major cross-functional initiatives across mobile, platform, and backend teams from concept to measurable outcome.
• Stay hands-on: design and build the most complex, highest-leverage parts of the iOS codebase in Swift and SwiftUI.
• Set engineering standards for architecture, quality, performance, and reliability, and get them adopted across teams.
• Mentor Staff and Senior engineers and help grow Radar’s next generation of technical leaders.
• Help drive the technical vision and architecture as we rebuild Radar’s mobile apps, a rare chance to define the foundation of our next-generation product.
• Plan and drive the migration of existing customers from legacy apps to the new app, keeping the experience smooth and low-risk with minimal disruption.
• Keep supporting and improving Radar’s legacy products, balancing their stability and customer needs against investment in the new platform.

ABOUT YOU

Required:

• You have extensive experience building and shipping iOS applications, including setting the technical direction for large-scale, widely used apps.
• You have deep expertise in Swift, SwiftUI, UIKit, and Apple platform internals, including concurrency, performance, and memory management.
• You have set technical strategy across multiple teams or an organization, with clear influence on product and business outcomes.
• You have led major, multi-quarter initiatives across functions and delivered measurable results.
• You are able to define your own priorities and problem space with little direction, and you work with a high degree of autonomy.
• You are skilled at influencing without authority and can get senior engineers and leaders aligned on complex technical decisions.
• You are an excellent communicator who explains complex tradeoffs clearly to technical and non-technical audiences.
• You are a proven mentor to senior engineers and a multiplier who raises the bar for everyone around you.
• You are energized by ambiguity and high ownership in a fast-moving startup.

Preferred:

• You have worked as a Staff+ engineer, or in an equivalent technical leadership role, at a company through a period of significant scale.
• You have led a major app rewrite or re-platforming and migrated existing users to it successfully.
• You have hands-on experience with Kotlin Multiplatform or other cross-platform code-sharing approaches on iOS.
• You have experience with modular app architecture, and build-system optimization 
• You have shipped features using newer Apple capabilities such as widgets, Live Activities etc.
• You are passionate about design detail, accessibility, and delightful user experiences.
• You have experience developing and shipping a configurable UI
• You have experience building iOS apps on gRPC and Protocol Buffers, including API contract design, streaming, and network performance tuning.
