Senior Mobile Engineer

We’re looking for a Senior Mobile Engineer who is excited to work across both iOS and Android (natively), and who strongly leverage AI-assisted development to move faster, improve quality, and reduce friction in large production codebases. You’ll bring deep expertise in one platform (iOS or Android), with the ability and willingness to contribute meaningfully in the other. This role follows a hybrid schedule, with in-office work required on Wednesdays and Thursdays from our Toronto office to support collaboration, and flexibility to work remotely for the remainder of the week.

Requirements

Senior-level experience building and shipping production mobile applications; Deep expertise in iOS or Android, with strong proficiency in the other platform; Solid understanding of mobile fundamentals: lifecycle, performance, debugging, observability, and tooling; Experience working with modern mobile architectures and asynchronous programming; Comfort owning features in a large, production codebase; Ability to balance speed with quality, maintainability, and user impact; Experience mentoring other engineers or leading technical initiatives; Comfort working in ambiguous problem spaces and collaborating across disciplines; Hands-on experience using AI tools (e.g., Claude, Copilot, or similar) in real development workflows; Ability to critically assess AI output and validate it with tests, reviews, and incremental rollout; Interest in turning AI usage into repeatable team leverage, not just personal productivity

Nice to have
