About the Role

We are seeking a Senior or Staff Software Engineer to lead the development of our next-generation digital cockpit. This role focuses on delivering high-fidelity, real-time 3D environments for in-vehicle infotainment and advanced driver assistance visualizations. You will be the technical anchor for our 3D strategy, moving fluidly between high-level architecture and deep, hands-on implementation within industry-leading engines.

Responsibilities

• Engine Mastery: Take a primary, hands-on role in developing and optimizing our vehicle HMI using Unreal Engine (C++), Unity3D (C#) or a custom 3D rendering system.

• You will be responsible for building the core frameworks that power our real-time 3D clusters and HMIs.

• Architecture & Integration: Design the bridge between vehicle sensor data (SDV and VHAL) and the 3D scene graph, ensuring low-latency visualization of the vehicle’s surroundings.

• Embedded Optimization: Profile and optimize engine performance for automotive-grade SoCs, focusing on memory footprint, GPU utilization, and thermal efficiency.

• Tooling & Pipelines: Develop custom engine plugins and automated build pipelines to streamline the deployment of 3D assets from design to the target vehicle hardware.

Qualifications

• Hands-on Engine Expertise: For Unreal: Deep experience with C++, Blueprints, UObject system, and custom shader development (HLSL).

• For Unity: Mastery of C#, the High Definition Render Pipeline (HDRP), and custom package development.

• Graphics Programming: Strong understanding of the modern rendering pipeline, including PBR, lighting, and post-processing, specifically for mobile or embedded targets.

• Core Languages: Expert-level proficiency in C++ and familiarity with modern languages like Kotlin or Swift for platform-level integration.

• Mathematics: Strong foundation in 3D math (vectors, quaternions, matrices) required for complex spatial transformations and camera logic.

Preferred Qualifications

• Experience deploying Unity or Unreal-based HMI onto Android Automotive OS (AAOS) or specialized Linux distributions. Familiarity with emulator-based testing environments (e.g., Cuttlefish) for 3D UI validation. Knowledge of functional safety standards and their impact on real-time graphics in a vehicle environment.
