Software Development Engineer II, Nav Native

The role

We are looking for smart, fast-learning engineers driven by the challenge of developing core components of the Mapbox navigation ecosystem. As a C++ Developer, you will: Build and maintain a unified C++17 library that runs seamlessly across iOS, Android, and low-power automotive embedded hardware. Analyze and improve map-matching and dead-reckoning algorithms using real-world data from millions of vehicles. Implement route-following features, including high-frequency route progress reporting, deviation detection, and timely instruction delivery. Work on road object matching (OpenLR) and live traffic incidents to give drivers a predictive "window" into the road ahead. Design predictive caching for routing tiles and manage complex on-board resources like junction views and signposts. Integrate and extend the Valhalla routing engine to support offline routing and route refresh controllers. Thoughtfully leverage AI tools in your design and development workflow to increase efficiency and code quality. Strong proficiency (min 7 years of experience) in C++17 (or later) with a deep understanding of the language specification, memory management, standard library, and multi-threading. A passion for writing clean, fast, and portable code that adheres to strict CPU and memory constraints. Experience working with complex graph-based structures, data structures, and spatial algorithms. Proven experience developing cross-platform code (Linux, mobile, or embedded systems). Strong English skills, with the ability to explain complex technical trade-offs to both peers and stakeholders. Would be a Plus Familiarity with navigation concepts (dead reckoning, bearing, Electronic Horizon, or OpenLR). Experience working with IMU, OBD-II, or GNSS data. Background in computational geometry or safety-critical features (ADAS). Experience with or contribution to open source routing engines.
