Got vagina?

Then P.RM Travels has a job for you.

In the classified section of The Hindu, I happened upon a rather hilarious ad, which I will recreate below:

Singapore-Walk-In

2. MEP-Coordinators - able to do electrical / mechanical maintenance work in building, petro- chemical industry
3. Process Technicians - Petro- chemical exp must
4. Female (exp not essential)
5. QA/QC-Inspectors - precision industry experience must
...
To apply, to know salary & nature of job log on to our website. www.jobonhand.com

Does this strike anyone else as extremely shady? They're not asking for an executive assistant or an administrator, and experience is explicitly unnecessary. So what, dear friends, could the job profile for this female be?

(And, OK, if you go to the Web site, they do request a "female operator." However, I fail to see why they couldn't put this in the ad, if they're going to list details about the other jobs -- apparently targeting men -- that are a bit more salient than specifying desired genitals.)
