  • Major interest and expertise in Distributed Systems design, development, optimization and operation, especially in byzantine context.
  • Solid awareness of the key challenges rising from distributed data storage (e.g. availability, consistency, scalability).
  • Strong hands-on experience in securing p2p distributed systems (e.g. against typical attacks such as Sybil attacks, Eclipse attacks, etc.).
  • Deep understanding of key metrics in distributed networks (e.g. latency, throughput).
  • Strong general networking knowledge (DNS, TCP/IP, HTTP, load balancing, QoS).
  • Strong programming background in one or more of the following languages: Rust, C++11, Go.
  • Demonstrated leadership capabilities.
