Is this a legitimate company? Swiss Alarms LLC?

Hi I applied for a job at Craigslist. A representative sent me an e-mail talking about the job duties transferring payments in a trial period or something like that. I don't know anything about the company other than the e-mail of the two people that sent me e-mails and the name of the company, not even the phone number. I got an e-mail saying I got the job, but feeling kind of suspicious. Any ideas? Thanks
