Tom Macbeth, VP of platforms at Shiva?s Edinburgh office, left the company earlier this week, prompting speculation engineering will move to the US.
He masterminded Shiva?s new switch which was shown at Networld Interop in the US earlier this year and was the inventor of the first ISDN router when he was with Spider, taken over by Shiva.
At the same time, Shiva nominated James Zucco, former operating officer at the company, to be its CEO, with founder Frank Ingari staying as chairman.
But Shiva insisted that Macbeth?s leaving has nothing to do with Zucco?s appointment. A US corporate representative said: ?We have been in discussions with Tom for a number of months. He spent 90 per cent of his time travelling and wanted to spend more time with his family.?
But an insider at Shiva in the UK said he thought this was stage one of a move to shift its engineering to the US. He added that it was internal politics at Shiva which caused Macbeth to depart.
The corporate representative denied that Shiva had any plans to move its engineering from Edinburgh to its corporate headquarters in Massachusetts. ?On the contrary,? she said. ?Our facility at Edinburgh will be staffing up.?
Macbeth?s position has been filled by Mike Allan, who formerly worked at the company, she added.
Zucco was formerly at Lucent, AT&T and MCI. AT Lucent he was president of network communications software.
