Mallaghan Engineering Limited makes ground support equipment used in the aviation industry. The company's products include passenger stairways and high lift trucks used to load catering supplies.
The company is now looking to develop an airport bus and is extending its factory premises.
The move will double the firm's workforce and Invest NI is offering £3m in grants towards developing new products. The new jobs will add £5m to the local economy annually in salaries.
"We aim to further grow our market share of the global aviation industry and will be targeting opportunities in the US and China," said Ronan Mallaghan, the firm's chief executive.
The firm's Managing Director Martin O'Hanlon said they export 70% of their products outside the EU.
"We'll deal with whatever Brexit throws at us. We're used to exporting. Yes our supply chain is fully integrated into the EU and UK but we'll just deal with it as it comes along," he said.
The jobs will be created over the next five years.
