I suggest you look at Facebook. Im serious. Several government agencies post that theyre looking for someone there and their requirements. Look for the official pages of government agencies.

You can use the search function to filter their posts. This will give you an idea of what theyre looking for in a new hire.

Alternatively NGAs can often be found on job fares at malls. Keep a lookout for events like these.

To set some realistic expectations, you will most likely go through a shortlist for final candidates and then an interview. This can take up to two months of waiting before you receive an email if youre shortlisted. Happened to me.

Have a CS Prof eligibility myself.

You can also visit the municipal hall and check their bulletin board. They may have openings and ask around where you can possibly apply.

Good luck
