The role

This company builds the AI workspace that the world's largest banks and regulated institutions run their document-heavy work inside. They're growing rapidly, backed by leading investors, and transforming how major financial institutions produce and validate client-ready work. They've shipped everything on the web, but now need a native iOS app — not a wrapper, but a proper, performant experience for iPhone and iPad. You'll own the entire iOS architecture, from interaction patterns and offline behavior to testing and release. This isn't just implementing features; it's defining the mobile future for a product used by global teams.
