Is there any way to get my certificate again as it is required for my job?
A new paper certificate? No.
However, if you create your CertView account and link it with your Oracle Testing ID, you will have access to all of your test information. One of the options from Certview is to send your certification credentials to a third party (i.e. your employer).
You could also contact Oracle Certification Support http://bit.ly/KMsuH3 and request soft copies of your certificates. However, you should also follow the steps that Matthew mentions above - in addition to contacting Oracle Certification Support.
