This is to certify that Mr. *** has been associated with our organization from January  dd, 2003 to January dd, 2006. His designation at the time of relieving him of duties was Embedded Software Engineer and was reporting under embedded & system software Division[is this statement fine].

  His duties during his tenure included simulating and developing system software for DSP based engineering systems.[should I add more specific duties or this broader statement is more then  needed  ] He exhibited a high degree of professionalism and performance in his work[/duties].

We appreciate the services rendered by him and we sincerely wish him all the success in his future endeavors.

There are a couple of weird phrases in your first paragraph. Why 'associated with' instead of 'worked for'?

at the time of relieving him of duties - this makes him sound as though he was forced out, dismissed, etc and creates a very poor impression of him. People are 'relieved of their duties' by force. Just say 'when he left'.

TO WHOMSOEVER IT MAY CONCERN

This is to certify that Mr. *** was an employee of **** from January  dd, 2003 to January dd, 2006 and was designated as Senior Software Engineer.

His Duties during this tenure were simulating and developing system software for DSP based engineering systems.( if you have done testing, will be good if you add that) His performance during his stay was satisfactory.

We wish his future endeavor all success.
