John Streit joins from Carlson Marketing as head of delivery overseeing digital projects, while Nic Goodall joins from Dare as head of quality assurance.
Tom Cole takes over the role of head of creative technology at Agency Republic, from David Cox who is returning to Australia. Cole was recruited from Make Digital, the creative company he co-founded.
The two new roles will add to Agency Republic's award-winning creative agency. Cole brings with him eight years of Flash development, while Streit has more than 12 years' experience in digital delivery.
Agency Republic is also expanding its planning team with the recruitment of Matt Saunders, who will work on Diageo and BBC projects.
Last year, the interactive agency won several high-profile pitches for its portfolio, including EA Games, Hovis and RAF.
