Conduct rigorous testing and debugging at the kernel level to handle system updates and compatibility issues.
We hope you:
Can autonomously figure out solutions to engineering challenges
Value clear and frequent communication (we do a lot of reading and writing)
Enjoy being a generalist and are not tied down to a specific framework or surface area of our codebase
Are naturally curious and willing to learn something they don’t have experience in
Have good judgement of when to ship: perfect is the enemy of good
