About 1,000 offshore jobs are expected to be created at the development at Alexandra Dock, which received final planning consent last week.
It will include a blade manufacturing plant and a servicing and maintenance facility along with storage and assembly areas.
The first major wave of 250 energy jobs are expected to be advertised before Christmas.
The German engineering giant has already said it expects to recruit about 90 per cent of the workforce from Hull and the East Riding.
Speaking at a council scrutiny meeting, the authority's regeneration manager Mark Jones said: "Until now, this industry has been fairly rootless but Siemens is definitely up for employing local people."
Mr Jones, who played a key role in negotiations to secure the company's investment in Hull, said there would be "no such thing" as an unskilled job at the development.
"We do not want to frighten people away but we should not undermine the of these jobs," he said.
"I believe there is no such thing as an unskilled job anymore and while some of the jobs here will be low- skilled, they will also be high-demand jobs.
"There will be several elements to the blade manufacturing process and people will have to be able to work as part of a team and in a controlled environment."
