## About the Role

* 12+ years of professional software engineering experience.

 * Deep expertise across modern and legacy iOS frameworks, Swift, and Objective-C.

## Description

We build native foundations that support seller-facing software across multiple teams. You will set direction for iOS architecture, performance, reliability, security, and developer experience. You can start from an important, unowned problem, prove a direction through hands-on work, and create a program other teams can join. You may begin as the sole expert, but your goal is to create leverage through clear interfaces, documentation, and new technical leaders., * Define strategy, architecture, standards, and measures of success across teams and applications.

 * Build prototypes, reference implementations, and the critical path needed to prove the direction.
 * Lead multi-quarter migrations and foundational initiatives through broad adoption.
 * Establish durable practices for quality, testing, observability, release safety, and maintainability.
 * Develop senior engineers and create an ownership model that does not depend on you as a permanent bottleneck.

How you work

 * You are self-directed and actively gather the context, data, and domain expertise needed to make sound decisions.
 * You move independently within your scope and seek alignment when decisions affect other teams or create long-term commitments.
 * You use AI tools to investigate and deliver at greater scale. You verify the work and remain accountable for security, reliability, and customer trust.
 * You measure success through adoption and seller or customer outcomes, not the production of frameworks or documents., We may use automated AI tools to evaluate job applications for efficiency and consistency. These tools comply with local regulations, including bias audits, and we handle all personal data in accordance with state and local privacy laws.
