Citrix

Citrix's goal is to enable everyone to work from anywhere, any time, and on any device. Citrix Hypervisor (formerly XenServer) is a virtualization product built on top of the open-source Xen hypervisor and XAPI toolstack. Tech stack: C (hypervisor, kernel, userspace), OCaml, Python, CentOS 7.x. For the "hypervisor engineer" role prior experience with a hypervisor is not necessary, we also welcome developers who have experience with kernel-level development. OCaml experience is not required for this role. You'll have the opportunity to actively contribute to various open-source projects that are part of the product.
