Mobile iOS & Swift Engineer with MapBox Navigation SDK

We are looking for an experienced Senior iOS Developer to maintain and enhance a delivery operations application that provides drivers with turn-by-turn navigation, route visualization, rerouting, and live delivery tracking. The application originally used Mapbox Navigation SDK v2.x and has been migrated to v3.x. We need someone who has personally worked with the v3.x SDK in a production navigation application, not someone whose experience is limited to displaying a map or basic Mapbox Maps SDK integration. When applying, please explain specifically how much hands-on work you have personally done with Mapbox Navigation SDK v3.x. Please describe whether you have worked on a production app where turn-by-turn navigation was running on v3.x and your direct involvement with the route lifecycle, route progress, rerouting, and route-line implementation. We are looking for someone who can confidently take ownership of the existing navigation layer and work through complex production issues independently.
