Fellowship in Database Engineering


Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.

CERN’s computing fellowships are designed for recent graduates offering career development in a unique, international environment.


Job Description

At the Compact Muon Solenoid (CMS) experiment, we handle several aspects of the offline preparation of the data for physics analysis.

You will be part of the CMS Physics Performance and Dataset (PPD) group.

You will manage all programming and infrastructure support of the CMS databases related to online and offline conditions, data handling and processing related to alignment and calibration. You will interact strongly with physicists in the Alignment, Calibration and Database (AlCa-DB) team, which coordinates the detector and physics object groups for the preparation and deployment of the alignment and calibration conditions. 

In order to provide the best service, you will work in close collaboration with the CERN IT DBAs to ensure the stability of the services and coordinate scheduled updates and other maintenance tasks.

You will provide and maintain tools for the users to efficiently handle the conditions and calibration data in the database (O2O, Dropbox, GlobalTag, etc.) and the distribution of the conditions to the world-wide grid computing farms through the Frontier system. In addition, expertise and guidance is given to handle new use-cases.



Eligibility criteria

  • You are a national of a CERN Member or Associate Member State;
  • You have a Bachelor’s degree in Information Technology, Computer Science, Engineering or other related field;
  • You have no more than 4 years’ experience after completing your highest diploma.

Essential skills and experience

  • Excellent knowledge of database and database handling in general. Specifically ORACLE DB which is used as the main DB, and DB handling tools, such as SQL, sqlalchemy;
  • Excellent programming skills with proficiency in both Python and C++. 

Desired skills and experience

  • Expert-level knowledge of the techniques used to manage software releases and testing procedures;
  • Expert-level knowledge of the database query language (SQL) and Object Relational Mapper (sqlalchemy);
  • Good knowledge of modern web frameworks (CherryPy, Flask) and technologies (jQuery, AJAX).
