I got a reply right away:

Hi Christopher,

We posted your job with the aim of getting your iRobot higher exposure among candidates. I know how competitive the market can be, especially for finding great developers.

I'll gladly remove the position but, personally, I highly recommend keeping it just to see which candidates the position attracts (at no cost to you). Any CVs submitted are emailed directly to you.

Please consider keeping the jobs and posting any future openings that you may have at Nava on Jobsy.com (free).

Thanks,

Allon Jobsy.com
