Select Subquery To Return COUNT

I have 2 tables, Jobs and Categories.
Each job belongs to a category. At present, I am returning all categories as follows:
SELECT categoryID, categoryName FROM TCCI_Categories
What I'm trying to do, is also return the number of jobs assigned to each category, so in my web page display, it would show something like this:
Engineering(5)
Mechanical(10) etc.
My db currently has 5 categories, with only one job assigned to a category. I tried the following sub-query, but instead of returning all the categories with their job counts, it just returns the category that has a job assigned to it:
SELECT c.categoryID, c.categoryName, COUNT(j.jobID)
FROM TCCI_Categories c, (SELECT jobID, categoryID FROM TCCI_Jobs) j
WHERE j.categoryID = c.categoryID
GROUP BY c.categoryID, c.categoryName, j.jobID
This is the output when I run the query:
categoryID categoryName  Column1
----------------  ----------------------  ------------------------------
32              Engineering     1
How would I fix this?
