Senior / Staff Software Engineer, iOS

What You’ll Do

• Design and build Suno’s iOS app across creation, discovery, playback, and social experiences
• Create foundational abstractions and libraries for performant, highly interactive audio and animation
• Collaborate closely with product and design to shape the feel, flow, and direction of the app
• Optimize for performance, responsiveness, and delight — from frame rates to load times to micro-interactions
• Instrument and monitor the app’s health, and iterate rapidly post-launch based on real user data
• Set the technical direction for the iOS platform and define architectural patterns the team builds on
• Mentor engineers and raise the bar for code quality, abstractions, and engineering culture

What You’ll Need

• 5+ years (Senior) or 7+ years (Staff) shipping production iOS apps
• Advanced expertise in Swift — we use SwiftUI with UIKit where necessary
• Deep experience building fluid, polished animations and translating design prototypes into robust, production-grade code
• Strong sense for performance: you profile, benchmark, and fix, from UI thread contention to network efficiency
• An obsession with great user experience — you care about the details that most engineers skip
• Comfort with ambiguity: you can scope work, make tradeoffs, and ship without a fully-defined spec
• A collaborative spirit and strong communication — you work fluidly with designers, PMs, and backend teams

Strong Plusses

• Experience working with audio playback systems, streaming pipelines, or real-time audio
• Experience with social product features: feeds, follow graphs, notifications, publishing flows
• Background designing or consuming mobile-first APIs in close collaboration with backend engineers
• Track record building 0→1 consumer products at a fast-moving startup
• Technical leadership or mentorship experience (especially important for Staff candidates)
