Fellowship in Frontend Web Developement

CERN

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

Are you talented in designing intuitive web interfaces? Do you feel confident in writing efficient, well-documented, and modular JavaScript code? Do you keep yourself up to date with new technologies in your field? Then join CERN’s Electrical Power Converters Group! We are seeking a frontend developer to work on web applications used by power converter experts, to work with a large distributed control system consisting of more than five thousand power converter controllers. These are used to precisely control the current delivered to the magnets in CERN’s accelerator complex in order to guide and focus particle beams.

You will join the Converter Controls Software Section and enjoy creating and extending the user interfaces of the group’s expert tools in close collaboration with users and other team members.

As part of an agile team, you will collaborate closely with four developers who are working on the full stack of the group’s expert tools.

You will contribute to the design, development, deployment, maintenance, and support of existing and new web applications and services.

You will become the main responsible for a selected subset of existing web applications such as the signal visualisation and inspection tool PowerSpy. This role mainly comes with frontend related tasks but it will also require you to become familiar with and work on the Python backends.

On the frontend, we use mostly:

  • JavaScript (ES6+)
  • Vue.js
  • Bootstrap 5

On the backend, we use:

  • Python
  • FastAPI, Django and REST APIs
  • PostgreSQL and Oracle

Section wide, we use:

  • Git for version control
  • Gitlab CI/CD for continuous integration
  • Jira and Gitlab for issue tracking
  • Confluence for wiki articles

Additionally, you will be part of a support team that is responsible for tasks such as helping power converter experts to insert definition and configuration data into our system. Approximately every three months, you will be on stand-by duty for one week including nights, weekends and public holidays.
