First of all, if the travel is required by your company, then visa process should be their concern, not yours.
On the other hand, you should check this site for information about visas to Romania. According to this page "Blue card" can be either
The residence permit issued by a Schengen member state
or
The long-term resident's EC residence permit (the validity of which is of 5 years or more) issued by a member state of the European Union.
If "Blue card" fits one of those conditions, you don't need an additional visa.
If you want to be 100% sure about visa the best way would be to call to the diplomatic mission of Romania in the country of your current residence & describe the situation.

As stated in Timatic, the database used by airlines:
Visa required, except for passengers with a residence permit issued by Bulgaria, Croatia, Cyprus or a Schengen Member State for a maximum stay of 90 days
A Blue card is a type of residence permit, so you do not need a visa.
