Timerjob is not working - it doesn't show up in central admin monitoring tab

Dear all,

I have enabled the timer job using the following class file and event receiver file. After enabling in powershell - the job is not appearing in job definition in central administration.

Any inputs are highly appreciated. Since I am new to SP2010 - I will then try to debug the timer job.
