Experience developing and testing for Apple platforms using Xcode, SwiftUI, XCTest, and XCUIAutomation.
A deep curiosity and excitement for exploring novel approaches to testing Generative AI and machine learning features.
Bachelor's degree in Computer Science, Engineering, or equivalent professional experience.

Understanding of large language models (LLMs) and prompt engineering concepts as well as how to leverage them for tooling and development workflows.
Experience testing machine learning frameworks or other complex, non-deterministic systems.
Deep knowledge of developer tools, SDKs, or framework testing and validation methodologies.
Familiarity with continuous integration (CI) systems and advanced build automation.
Experience using Python for test automation, custom tooling, or machine learning pipelines.
