1. You need an explanatory or evocative translation, as this position doesn't have a widely known exact equivalent in the English-speaking world.

2. The term needs to be capitalized, as it is in French, to show it's a job title.

3. Attaché is usually translated as "officer," and it indicates that the person is an employee and agent of the entity that they're an attaché of.

4. Judiciaire means "judicial" (relating to the judiciary and/or the court system), not just "legal."

"Services Judiciaires" can be translated as Judicial Services, Judicial Administration or similar. If it's not a title but just a noun, it can be judicial authorities (I've seen news articles reporting that "les services judiciaires" said or did XYZ). Either Judicial Services or Judicial Administration would be fine here. If you use the latter, I would suggest changing the word order to keep "Judicial Administration" by itself. That enhances clarity, because if you say "Judicial Administration Officer," then "administration" could be misread as modifying "officer," when in fact the proper interpretation is that "judicial" modifies "administration."

Thus, you end up with a translation (Judicial Services Officer or Officer of the Judicial Administration) that makes clear we're talking about some type of governmental judicial-department officer in the Ivory Coast -- which is what the reader needs to know.
