Citrix builds the secure digital workspace technology that frees 400,000 customers to do their very best work from anywhere. By joining our award-winning workplace, you’ll be included in the globally diverse, collaborative team that values work-life balance. Come see why Fortune named us one of the 100 Best Companies to Work For®. Let’s innovate and grow together!

What we're looking for:

You’re a software engineer with experience of development and optimisation at a system level. We'd like you to join a high profile team working on Citrix Hypervisor which is a leading virtualisation management platform optimised for application, desktop and server virtualisation infrastructures.
 

Our team is focused on optimising whole-system performance by identifying bottlenecks and developing improvements to overcome them. The development team has a strong research approach, and involves collaborative work with other engineering teams and components (e.g., storage, graphics and data path, Windows virtual machines, Linux operating systems, cloud orchestration, toolstack, and low-level components such as the kernel and the Hypervisor).

Experience in a system performance role is valuable, but not crucial. Other valuable skills include a background in design of experiments, knowledge of statistical methods, and modelling and analysis of complex systems including operating systems and cloud services. Familiarity with operating system programming and/or functional programming is also an asset.

We work in a fast paced multi-technology environment: programming languages currently used include C, Go, Python and OCaml; operating systems include Linux and Windows.

Responsibilities

  • Analysis of software internals and behaviour to identify performance problem areas

  • Definition of scales of measure of performance in a sophisticated system

  • Proposing, prototyping and productising software changes to improve system performance

  • Working as part of a self-organising team, and providing daily updates of own work, within an agile framework

Qualifications and Requirements:

You’ll probably have a strong academic background with one or more degrees in computing, software engineering, mathematics or experimental sciences.

You’ll actively contribute to several open source projects (including Xen, Linux Kernel, and Xapi), using our agile development methodology and you’ll get to interact with customers, partners, other Citrix product groups, and with the open source community.

  • A body of experience developing software

  • Unix or Linux experience

  • Ability to learn new areas quickly and work at a detailed level right across the software stack

  • Ability to conduct a research project both on one’s own and within a team

In addition, experience in any of the following areas would be preferred:

  • Server virtualisation in general, and Xen or Citrix Hypervisor in particular

  • Windows Device Driver development

  • Distributed systems

  • Datacentre-sized deployments

  • Cloud infrastructure

  • Enterprise network and storage configuration

  • Linux kernel internals

  • Software profiling and performance analysis

  • Agile development practices

  • Open-source development processes, and interaction with open source communities

  • Interaction with customers

  • Knowledge of different types of programming languages, such as procedural languages (e.g., C, C++, C# or Java); scripting languages (e.g., Python); and functional languages (e.g., OCaml, ML, F# or Haskell).

Functional Area:

Software Development
