Two Irish technology companies Ammeon and DecaWave have announced 200 jobs.
IT professional services and consulting firm Ammeon and semi-conductor company DecaWave are each adding 100 positions.
Founded in Ireland in 2007, DecaWave develops integrated circuit products capable of identifying the specific location of any object, person or thing with centimetre-precise accuracy.
It has just raised €30m in fresh funding from leading venture capital funds led by Atlantic Bridge Ventures, as well as Enterprise Ireland.
The latest funding will double the total amount it has secured since it was set up.
It will use the money to help meet growing international demand for its products and to accelerate the development of its second-generation chip for the consumer and automotive markets.
It plans to take on 100 staff over the next three years to bolster its global engineering and sales teams.
The posts will be in engineering, R&D, sales and marketing and applications, with recruitment already under way.
Half the new positions will be in Dublin, with the remainder in the firm's other offices in Silicon Valley in the US, China, France and South Korea.
Decawave already employs 50 people and has more than 3,000 customers around the world.
Ammeon, meanwhile, is to add to its software engineering and consulting divisions, taking on 100 staff over the next 18 months.
Founded in Ireland in 2003, Ammeon is an IT professional services firm that carries out consultancy and offers software to other businesses.
Its clients include financial institutions, telecoms providers, automotive, transportation, government organisations, as well as the European Space Agency.
The company already employs 165 people in its offices in Dublin, the UK and across Europe.
The new recruits will work in development operations, cloud, integration and automation.
Ammeon's expansion is also supported by Enterprise Ireland.
Both companies announced their expansions at separate events this morning, which were attended by Minister for Business Heather Humphreys.
