Principal Mobile SDK Engineer

Platform

Role

SDK and navigation

• Design a unified SDK architecture that keeps the mapping and rendering layer private and replaceable.
• Build turn-by-turn guidance, route snapping, off-route detection, rerouting, ETA, and trip-state logic.
• Design idiomatic, thread-safe public APIs with a strong developer experience.
• Produce reference documentation, integration guides, migration notes, and sample applications.

Location, performance, and release

• Use GPS, accelerometer, and gyroscope sensor fusion to improve location quality in tunnels, urban canyons, and weak-signal areas.
• Optimize battery, memory, tile caching, and thermal behavior across long navigation sessions.
• Support background location and audio modes so guidance continues when an app is backgrounded.
• Deliver multilingual voice guidance including Arabic and right-to-left map labeling.
• Package and version binaries for private gated and public distribution channels.
• Test with unit, integration, and device tests, simulated locations, and recorded route replay.

Required qualifications

• 10+ years building mobile software, with a substantial part on iOS.
• Expert Swift and deep command of concurrency, background modes, application lifecycle, permissions, memory, and power behavior.
• Track record building and maintaining SDKs or libraries used by external developers; understands semantic versioning, backward compatibility, and module stability.
• Advanced production experience with a major map or navigation SDK, such as Mapbox, MapLibre, Google Maps SDK, or equivalent.
• System-design ability across complex internal engines and simple public interfaces; writes documentation and demonstrates self-direction.

Strong advantages

• Working proficiency in Kotlin and Android; vector tiles, Metal or OpenGL rendering, GeoJSON, Mercator, and WGS84.
• Computational geometry, Kotlin Multiplatform or shared-core approaches, and offline-first handling of large local map datasets.
• CarPlay or embedded automotive delivery; Arabic-language products or right-to-left interfaces; experience growing and leading a small engineering team.

Hiring process

• The process consists of three conversations, without algorithm puzzles or a take-home project lasting more than a few hours.
