Performance is one of the key features of virtualization products. Higher performance can often help you to decide which product to buy. Our project deals with researching the performance of the two leading virtualization technologies: Virtuozzo Containers and Parallels virtual machines.The project tasks require fundamental knowledge of modern operating systems (OSes) and computer systems, which you can gain directly from the product developers. You will have an opportunity to work on unique tasks, such as calculating the maximum density of virtual servers per physical server, or testing the productivity on NUMA architecture with the number of CPUs of up to 128, and so on.
Responsibilities:
* сhecking performance using standard industrial tests; * мaking up reports/presentations that provide comparison with our competitor, including testing methods and problem analysis; * active cooperation with developers, finding out the requirements for performance tests; * writing tests for subsystems specific for virtualization technologies (file subsystems, scheduler, net, memory manager, etc).
Basic Qualifications:
* knowledge of modern OS working principles; * experience in working in Linux environment; * experience in programming on the C language; * desire to develop one’s skills rapidly.
Preferred Qualifications:
* experience in system programming (programming on the C language, Assembler), knowledge of the x86/amd64 architecture; * experience in administrating Linux; * experience with performance tests from the leading vendors (SPEC, Intel, TPC, etc); * understanding of the data collection process (detecting bottlenecks, monitoring resource usage, ensuring statistical reliability of the experiment and its accuracy); * experience with profiling tools (Intel vTune) and experience in performance optimization.
Salary and Benefits:
* сompetitive salary, great benefits; * free meals at the office; * dental and medical insurance; * learning opportunities; * our office is located in Moscow in a walking distance from the Otradnoye subway station.
