Bonus Skills:

* RTOS Experience
* Kernel Driver Development Experience
* Understanding of GPU memory access patterns, data movement
* Understanding of x86-64 and/or ARM v8 compute architecture

Perks:

While doing meaningful work is the best perk of all, we also offer the following programs and benefits to support the extraordinary humans who serve as the backbone in making our robot cars go:

* The opportunity to solve difficult problems that have immediate and valuable real-world applications
