What gives software development engineers their buzz? Technical staff at Euristix cite the sheer variety of the work, the challenges the work throws up and the co-operation between colleagues as the aspects of their work that they most appreciate.Since it was founded in 1990 by Dr Jim Mountjoy and Brian Alton, the telecommunications software development company has quickly established itself as one of Ireland's software leaders. The Dun Laoghaire-based company, boasts an office in San Jose, California. It has a staff of 140. Almost all Euristix technical staff are graduates.The company is growing at a rate of 80 per cent each year. Over the next 12 months, Euristix expects to recruit up to 100 new computing staff, according to engineering resource manager Anthony O'Callaghan.The company's customers are blue-chip telecommunications operators and equipment vendors in Europe, Japan and the United States. It operates two divisions - Advanced Telecommunications Software Services (ATSS) provides a customised telecommunications software development service for network equipment vendors and operators and RACEMAN Technologies supplies network and element management technologies for operator networks.Euristix has developed a number of products, including Titan 5000, for the Chicago-based Tellabs, the world's largest vendor of telecommunications equipment.Because the software industry is young, there's plenty of room for career moves. You could find yourself coming in as an engineer, discovering other talents and moving into another area. For example, Euristix international marketing manager, Irene McGoey, came to the company armed with a computer science degree from Magee College, University of Ulster, and an MBA in international marketing from DCU. Anthony O'Callaghan, who is responsible for recruitment and staff development, came to Euristix as an engineer - he holds a masters in civil engineering with a strong computing content from UCC
