This role can be performed remotely from anywhere within the United States

The Fullstory Mobile team is dedicated to building intuitive, privacy-conscious native libraries that help app developers create better user experiences. We sweat the details to ensure our tools are thoughtfully engineered, easy to integrate, and built with care. As a remote-first team distributed across North America, we’re looking for a collaborative and technically skilled communicator with deep systems programming expertise to help shape the future of our industry-leading behavioral data platform.

As a Senior iOS Engineer, you’ll design solutions that give mobile teams deep, actionable insights into how users interact with their apps, without compromising performance or privacy.

In a typical day, you might:

Use advanced techniques for reverse engineering, disassembly, decompilation, and debugging, to analyze the inner workings of iOS frameworks and third-party code in order to reconstruct accurate representations of user sessions in our customers’ apps, with a strong emphasis on end-user privacy.
Write cross-platform code in Rust for shared crates, some of which handle activities like stripping potentially private information, networking utilizing Flatbuffers, automated testing, and performance optimizations with asset uploading.
Work alongside specialists in our Go APIs and canvas-based-typescript frontend to ensure impeccably low-performance overhead on the device and high fidelity replay of sessions on our site.
Anticipate and engineer support for new iOS platform-specific features, such as SwiftUI.
Innovate new feature ideas to enable customers to build better digital experiences and the mobile team to work smarter.
Leverage AI as a productivity multiplier to design creative solutions and derive actionable insights that drive team goals.

Here’s what we’re looking for:

5+ years of technical experience.
Deep systems programming knowledge and an eagerness to apply that knowledge to iOS; while iOS/macOS experience is valuable for this role, it is not required.
Experience mentoring less experienced engineers and would be willing to eventually take a leadership role in ensuring our iOS offerings are best-in-class.
The ability to help the team complete timely releases, wisely balancing competing concerns to deliver a great product.
The ability to gain a solid understanding of customers’ needs and offer constructive feedback to the cross-functional team as we meet those needs.
Bachelor's degree in Computer Science or a related field.

The impact you will have in 6 Months:

Diagnose and resolve complex issues in our SDK as it runs inside some of the most widely used consumer apps in the App Stor
