Senior / Staff Software Engineer, iOS

Stack

Responsibilities

• ▹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 app health, and iterate rapidly post-launch based on real user data
• ▹Set the technical direction for the iOS platform and define architectural patterns (Staff level)
• ▹Mentor engineers and raise the bar for code quality and engineering culture

Requirements

• ▹Advanced expertise in Swift — SwiftUI with UIKit where necessary

• ▹Strong sense for performance: profiling, benchmarking, and fixing issues from UI thread contention to network efficiency
• ▹An obsession with the UX details that most engineers skip
• ▹Comfort with ambiguity: scoping work and shipping without a fully-defined spec
• ▹A collaborative spirit and strong communication with designers, PMs, and backend teams

Nice to have

• ▹Experience with audio playback systems, streaming pipelines, or real-time audio
• ▹Experience with social product features: feeds, follow graphs, notifications, publishing flows
