• Design and evolve shared infrastructure, APIs, and abstractions that scale across multiple iOS SDKs.

• Collaborate closely with Product, and Customer Support to ensure SDKs meet real customer needs.

• Lead cross-team technical discussions, reviews, and architectural decisions that span multiple SDKs.

• Improve developer experience through better APIs, documentation, tooling, testing strategies, and sample apps.

• Mentor senior and mid-level engineers, raising the overall quality and effectiveness of the team.

You'll be a great addition to the team if you have:

• A strong focus on developer experience and empathy for the engineers who use your work.

• Expertise in iOS platform internals and best practices.

• A track record of technical leadership where others look to you for guidance and decision-making.

• Strong judgment in making tradeoffs between API design, performance, backward compatibility, and speed of delivery.

• Comfort working across team boundaries and influencing without direct authority.

• A high bar for code quality, testing, and long-term maintainability.

• The ability to explain complex technical topics clearly to both technical and non-technical partners.

At a minimum, you need to have:

• B.S., M.S., or Ph.D. in Computer Science or a related technical field, or equivalent practical experience.

• 8+ years of professional software engineering experience, with significant time spent on iOS development.

• Deep expertise in iOS platform internals and best practices.

• Strong proficiency in Swift and Objective-C, with experience using modern iOS APIs, frameworks, and development tools.

• Experience designing public APIs with a strong focus on stability and backward compatibility.
