The overhaul, led by corporate affairs director Frank Rogerson, has seen a complete re-organisation of the department's structure to create a centralised corporate affairs division, which sits alongside key group functions such as sales and marketing, finance and human resources.
Former Imperial international affairs manager Jacqueline Smithson has been named head of group corporate communications, alongside Ian Bailey, who becomes head of corporate responsibility.
Alan Porter has been appointed head of legal and regulatory affairs; Marion Funck named head of legal and commercial, and Werner Rahn is promoted to lead the scientific and technical unit.
While the merger of Imperial and Reemstma saw 37 redundancies across corporate affairs worldwide, the group is now recruiting for newly created communications jobs.
Smithson said they are hunting for a PR manager and a media relations manager - two of four managers who will report to her.
Smithson said: 'When you bring together two big companies in one head office you are going to have some overlap in terms of responsibilities, but we think the re-organisation is a transformation and we are growing the function.'
Reemstma's former head of corporate comms Dieter Lukowski left after the merger announcement to launch his own PR agency in Germany.
Smithson confirmed that there are no agency changes planned.
