More

In this role, you will join a specialized iOS engineering squad focused on rapid experimentation and product hypothesis validation. You will be responsible for building, deploying, and iterating native iOS features in a high-scale, social-financial ecosystem. Beyond writing code, you will architect AI-native workflows, leverage experimentation frameworks, and collaborate closely with Product and Data teams to ensure every feature is measurable, scalable, and production-ready.

What you can expect from this role (Responsibilities)

Develop and iterate native iOS applications using Swift, building modular UI components with SwiftUI while maintaining and refactoring critical flows in UIKit.

Architect experimentation-ready solutions using feature flags and A/B testing systems (e.g., LaunchDarkly or internal tools).

Leverage AI-native tools (Claude Code, Cursor, GitHub Copilot) to automate repetitive tasks such as unit tests, documentation, and scaffolding experimental features.

Manage complex application state using scalable architectures such as RIBs, MVVM+C, or The Composable Architecture, ensuring isolation of experimental features.

Integrate with high-performance APIs using GraphQL (Apollo) and REST, maintaining low latency in data-heavy flows.

Collaborate with Product and Data Science to define success metrics and instrument experiments using tools like Mixpanel or Segment.

Optimize and maintain CI/CD pipelines, enabling fast, confident releases to beta and production environments.

Ensure code quality, observability, and long-term maintainability while supporting high-velocity experimentation.
