About the role

Key responsibilities & impact

Own the end-to-end architecture of the mobile SDK
Design a unified architecture that keeps the underlying mapping and rendering layer private and replaceable
Implement core navigation logic including turn-by-turn guidance, route snapping, off-route detection, rerouting, ETA, and trip state
Design idiomatic, thread-safe public APIs that hide internal implementation details
Create reference documentation, integration guides, migration notes, and working sample applications
Improve location quality through sensor fusion across GPS, accelerometer, and gyroscope
Optimize battery, memory, tile caching, and thermal behavior during long navigation sessions
Implement background location and audio modes for guidance when applications are backgrounded
Support multilingual voice guidance including Arabic and right-to-left map labeling
Own binary packaging and versioning across private gated and public distribution channels
Establish unit, integration, and device testing with simulated location and recorded route replay
Set architecture and engineering standards while remaining hands-on
Work alongside routing, search, and tile teams
Report directly to the Founder and CEO
Grow and lead the mobile team as the SDK matures

Requirements

What you’ll need

10 or more years building mobile software, a substantial part of it on iOS
Expert Swift, with deep command of concurrency, background modes, application lifecycle, permissions, memory and power behavior
Proven experience building and maintaining an SDK or library consumed by developers outside your own company
Understanding of semantic versioning, backward compatibility, module stability, and breaking changes
Advanced production experience with a major map or navigation SDK, such as Mapbox, MapLibre, Google Maps SDK, or equivalent
System design ability at the boundary between a complex internal engine and a simple public surface
Ability to write documentation as part of the deliverable
Self-direction and judgment
Working proficiency in Kotlin and Android is a strong advantage
Knowledge of vector tiles, Metal or OpenGL rendering behavior, GeoJSON, Mercator, and WGS84 is a strong advantage
Knowledge of computational geometry, including bearings, distances, line snapping, and polygon intersection, is a strong advantage
Kotlin Multiplatform or shared core experience is a strong advantage
Offline-first behavior with large local map datasets is a strong advantage
CarPlay or embedded automotive delivery experience is a strong advantage
Arabic language products or right-to-left interface experience is a strong advantage
Experience growing and leading a small engineering team is a strong advantage
