C POSIX Software Engineer @ Citrix

Citrix's Xen Platform team works as part of the Xen Open Source community on the world-renowned Xen hypervisor, powering over 90% of today's cloud, including Amazon EC2, Rackspace Cloud and Linode. Xen is widely acknowledged as the fastest and most secure hypervisor in the industry.

We are looking for experienced C POSIX software engineers to help us improve the userspace side of the Xen software stack: XL/Libxenlight, Qemu, etc.

The successful candidate will be comfortable working with low level POSIX interfaces and writing stable library APIs. Ideally candidates will have already worked on other Open Source projects in C, contributing code or ideas, and know how to interact with a vibrant Open Source community, mainly through mailing lists like the LKML.

The core of the Xen project was originally developed in the Computer Laboratory of the University of Cambridge and spun out as the company XenSource which was acquired by Citrix in 2007. The Xen team is still based in Cambridge, UK and therefore this role is based in the modern Citrix research and development centre on the Cambridge Science Park. However a self-motivated person with a proven track record could work from anywhere with a good bandwidth connection.

Responsibilities:

• design, implement and deploy new toolstack capabilities;
• help maintain libxenlight, the low level library for toolstack operations, fixing bugs and reviewing patches contributed by the community.

Requirements:

• experience with C software development on UNIX;
• experience with development on mailing lists and Open Source communities;
• extensive knowledge of the POSIX interfaces;
• strong skills in C; Python desirable;
• self-driven, capable of self-learning and seeing through a project from the beginning to the end;
