Job Description:

You will develop and optimize the core infrastructure that facilitates reliable, low-latency execution of on-vehicle robotics software. Your mission extends beyond building a rock-solid foundation for autonomous driving — you will also equip engineers with the tools needed to analyze system behavior, identify performance bottlenecks, and enhance robustness. In this role, you will contribute to existing frameworks, libraries, and tools while also designing and implementing new components across various mission-critical domains.

Job Responsibility:

Design and optimize low-latency interprocess communication and data flow monitoring
Develop high-performance event logging and structured telemetry
Implement safety-enhanced memory allocators and efficient memory provisioning policies
Build lock-free data structures and algorithms to support real-time system requirements
Work on network communication and coherency protocols
Develop on-the-fly component health monitoring and rapid response mechanisms for critical events
Manage on-vehicle configurations and system state validation
Optimize low-level OS interactions and fine-tune system performance
Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts
Ensure team compliance with QMS, monitor quality, and drive process improvements

Requirements:

BS in Computer Science, Electrical Engineering, or related field
Solid hands-on coding experience using C++14(or later)
Strong understanding of Linux development tools, including build systems, compilers, debuggers, and performance analyzers
Excellent written and verbal communication skills
Proactive problem-solving mindset: ability to identify, propose, and implement solutions

Nice to have:

Experience in writing, debugging, and profiling multithreaded C++ applications
Familiarity with robotics-related libraries such as ROS
Knowledge of real-time OS, database internals, network programming, GPGPU, or robotics
