Senior Software Engineer - iOS (Interaction and Animation)

This role focuses on how the app feels as much as how it functions. It is one of the few engineering roles in which motion, interaction quality, and visual clarity are primary responsibilities. The person in this role will define how we use animation across the iOS app, help express our brand through movement, and support product teams in building polished, scalable experiences.

• You will join the Mobile Platform team and work within a group focused on foundational mobile capabilities.
• Collaborate with other iOS and Android engineers, as well as product and design partners, to raise the quality of motion and interaction across the app.
• Design and build animations, transitions, and interactive UI components in SwiftUI, Lottie, and Rive.
• Work closely with designers to explore ideas quickly and turn the best ones into production-ready patterns.
• Help teams evaluate motion concepts, understand trade-offs, and use animation to improve clarity and engagement.
• Bring other engineers along as a key part of the role.
• Document patterns, create examples, pair with engineers when needed, and help the organization understand when and how to use motion responsibly.
• Build systems that enable product teams to ship polished interactions without relying on bespoke implementations.

• You are an experienced iOS engineer who cares deeply about how interfaces feel, not just how they function.
• You have a portfolio or examples of past motion or interaction work, and can explain the intent, decisions, and tradeoffs behind them.
• You understand animation tools such as SwiftUI animations, Lottie, and Rive, and know when to use each.
• You know how to build animations that perform well under real product conditions and how to debug issues that affect responsiveness.
• You work well with designers and can translate motion concepts into clear engineering plans.
• You communicate clearly with engineers, designers, and product partners and can guide conversations about what motion adds and what it costs.
• You are comfortable iterating quickly during exploration and being disciplined when shipping to production.
• You notice gaps in polish and take initiative to improve them without needing direction.

• Experience bringing brand expression into motion or helping shape a motion language for a product.
• Experience working with design systems teams or contributing to reusable interaction patterns.
• Experience with cross‑platform animation tools and collaboration patterns, especially when aligning animations across iOS and Android.
• Familiarity with haptics, gesture‑driven interactions, and micro‑interaction design.
• Interest in building lightweight tools or workflows that make it easier for teams to prototype and ship polished interactions.
