mSemicon operates a hybrid model regarding where activities are carried out. For the most part, given the nature of product development, duties are carried out in the company's main offices in Rathcoole, Co. Dublin. However, where it makes sense and does not compromise the effectiveness of project activity, some duties may be carried out remotely. This can extend to periods of a few weeks, even a month or two, where an employee may have reason to visit family overseas.
