The CSL degree course is one of the most interdisciplinary offered by the University, bridging both science and arts. It combines computer science with the mastery of a particular language (French, German or Irish) and with the study of linguistics, which is the scientific study of language in general and the associated technologies concerning language. As such its different strands foster a wide range of talents, from analytical problem-solving in computer science and mathematics to analysis of theories and data from linguistics, to fluency and cultural awareness in the language component.

Since the course began in 1985, graduates have moved on to careers that reflect the range of topics within the degree. Graduates will be qualified to work as language specialists, information technologists or software specialists in any of the IT, banking, translation, publishing or multi-media sectors. A number work as software engineers in international consulting firms. Some have embarked on careers in professional translation; others have moved into primary and secondary-level education. About 65% of graduates work in software engineering (whether in a mainly English speaking country or in a country where the language of the degree focus is the primary language); about 25% pursue research careers. A number of graduates now hold academic staff positions in Ireland and abroad. Another 10% tend towards a focus in technical translation. Some graduates have taken up employment in government service, e.g. the European Patent Office, the Irish Diplomatic Corps.
