• You have proven experience with storage systems, peer to peer systems, large scale distributed systems or simply system programming in general.
• You have previous experience of chasing problems through multiple layers of our software stack. You can be flexible and you are very curious.
• You are flexible and very autonomous. You won't be micromanaged in this role and will be looked to have experience thinking out of the box and coming up with simple and smart designs for complex issues.
• You have a previous track record of being pragmatic and believe in the value of simple solutions.
• You equally enjoy low-level and high-level programming. You have a taste for programming languages. You enjoy being a part of a team that challenges each other's designs
