While one of my hats is a network engineer and as an actual Engineer I can learn new skills quickly, the requirements for the position are quite detailed and with RUST ability being one of them, this narrows down the field a lot.
Normally a network engineer is about designing networks and keeping them working, it is usually using hardware & wires & router os/config and (lot) less programming. Maidsafe’s role requires that knowledge to be expressed in programming which does not suit a lot of network engineers. Now if I knew RUST (> 1 year experience) and had NAT traversal experience I would even consider applying for the role. But at my age the old gray matter is not as sharp as it used to be and a younger mind would be better because of that and also more importantly the longevity needed for the role. (And I have caring duties at home)
Well the project is slower to implement. The role would be currently filled by multiple other developers applying what excellent skills they have in that area. With the network engineer then the project would be able to progress that much faster and have someone who can be an expert in that area.
