Computing Fellowship: Full-Stack Software Engineer (Python/React)

  • Geneva, Switzerland
  • Full-time

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

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

Job Description

Indico is a web-based event management system which allows thousands of scientists around the world to conduct conferences and meetings, sharing materials and collaborating in an easy way. Indico is an Open Source Project, developed at CERN by an international team of passionate developers. It is used by CERN and 150 other institutes world wide, including the United Nations.

As part of the Indico Team, your main focus of work will be the implementation of new features aiming at improving the handling of personal data in Indico and migrating more parts of Indico’s User Interface to React.

Please note that this is a full-stack development position, but we generally accommodate for the preference of each developer when possible: we’d love to have someone with a keen eye for User Interfaces and strong CSS skills, but if APIs and server-side code is where you live, then you will be just as much of an asset to the team.

In the context of your job, you will:

  • Actively contribute to a large Open Source project on GitHub;
  • Work closely with developers, prototyping solutions and iterating on them in an agile environment;
  • Maintain code repositories and take part in code reviews of Open Source projects;
  • Work on DevOps infrastructure (OpenStack/Puppet and Docker/OpenShift).


Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State;
  • You have graduated, or are about to graduate, with a university degree (BSc or MSc level in computer science,engineering or another relevant course) and have no more than 4 years’ relevant experience after obtaining your degree;
  • Kindly note that experience prior to the latest obtained degree will not be taken into account for the calculation of your overall years of experience.

Essential skills and experience:

  • Strong knowledge of Python, ideally in web development;
  • Experience with JavaScript and in particular React (or a comparable framework);
  • Experience creating web application frontends with HTML5 and CSS;
  • Familiarity with Git and Open Source code hosting platforms like GitHub.

Desired technical skills:

  • Experience developing web applications using Flask and SQLAlchemy;
  • Experience prototyping and developing intuitive User Interfaces;
  • Passionate about software development and writing clean and robust code;
  • Basic knowledge of Linux system administration.

Having recent Open Source contributions or personal side projects on your GitHub account would be a plus.

Please note that CERN Staff members are not eligible to apply for a Fellowship.

Additional Information

In return, CERN will provide you with:

  • An employment contract for between six months (minimum) up to a maximum of 36 months.
  • A stipend ranging from 5,305 to 6,586 Swiss Francs per month (net of tax).
