Responsibilities:
  • 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.


Required Skills:
  • BS in Computer Science, Electrical Engineering, or related field.
  • Proficiency in 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.


Preferred Skills:
  • 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.


Salary Range:
  • $120,000 - $170,000 a year


Our compensations (cash and equity) are determined based on the position, your location, qualifications, and experience.
