Roles And Responsiblities Of Web Developer (HTML & PHP)

Dear All Seniors,
I am an HR executive in an IT Co. now I have been asked to design the complete roles and responsibilities of a web developer working on PHP and HTML.
Please guide me to design the R&R of Web Developer.
Prashant Rajora
(Hr. Executive)

Some of the roles and responsibilities of a web developer are as follows:
1- Identify bugs and fix them, trouble shoot and solve any related problems.
2-Help other members and provide the necessary assistance in the up gradation and maintenance of websites.
3- Create, design, test and apply web-based applications
4- Create the right code structures to resolve specific tasks.
5- Develop, program, test and debug all web based applications.
6- Prepare and coordinate intranet web updates and intranet website changes.

Thanx Amir for sharing knowledge with us but the problem is that I have to design the complete R&R for the Appointment letter.
So it would be good if it would be complete .
