3D Application Engineer (Automotive 3D Visualization)
About this role
42dot seeks a Senior/Staff Software Engineer to architect and develop next-generation automotive 3D visualization systems for digital cockpits and driver assistance displays. You'll lead hands-on development using game engines like Unreal or Unity, optimizing real-time 3D environments for in-vehicle hardware while bridging sensor data integration and graphics performance.
What you'll do
- Develop and optimize vehicle HMI using Unreal Engine (C++), Unity3D (C#), or custom 3D rendering systems
- Design the integration layer between vehicle sensor data and 3D scene graphs for low-latency visualization
- Profile and optimize graphics performance for automotive SoCs, managing memory, GPU utilization, and thermal constraints
- Build core frameworks powering real-time 3D clusters and infotainment displays
- Develop custom engine plugins and automated build pipelines for 3D asset deployment to vehicle hardware
- Establish technical direction for the company's 3D visualization strategy
What they're looking for
- C++ and Unreal Engine (Blueprints, UObject, custom shaders/HLSL)
- C# and Unity (HDRP, custom package development)
- Modern rendering pipeline (PBR, lighting, post-processing)
- 3D mathematics (vectors, quaternions, matrices, spatial transformations)
- Graphics optimization for mobile and embedded platforms
- Android Automotive OS (AAOS) and Linux deployment
- Functional safety standards for automotive environments
- Platform-level integration (Kotlin, Swift)
Benefits
- Competitive salary: $172,000–$237,800
- Work on cutting-edge software-defined vehicle technology
- Role in shaping the future of automotive infotainment and autonomous systems
- Opportunity to lead technical strategy and architecture decisions
