The EU institutions conclude a number of framework contracts (FWCs), published as tendering procedures, with external contractors for specific services that are required on a regular basis. These are generally large, multi-annual contracts focusing on certain thematic areas where the EU doesn’t have the required staff. For example, several FWCs are made with communication agencies to provide specific skills: every time the EU has communication’s needs on a project, they can contact one of the agency that will recruit consultants.
We didn’t find a specific link, but to name a few consulting agencies working for the EU and specialised in communication: Gopacom, Deloitte, Tipik, Pomilio Blumm, Novacomm, …
If you get hired by a consultancy agency, you have two types of contract:
Intra muros (IM) consultant
An intra muros consultant is a consultant that will work directly inside the EU institution: the person will get offered an access badge and have an office to work on the attributed project with the attributed Unit. At the end of the mission, the consultant will have to leave the building, unless they lobbied good enough to find another project to work on.
Extra muros consultant
As you guessed, an extra muros consultant is someone that is working for the institutions but do not have access to it. Therefore, a consultant relies much more on its recruiting agency to find more work.
Notice: Interim consultants are not to be confound with interim staff
that are hired by temping agencies
and often needed in secretarial roles for a maximum period of six months.
