Frequently asked questions about principal data scientist jobs

What is a ghost job?

A ghost job is a posting for a role the company isn't actively hiring for. Some stay up after the company fills the role. Others collect resumes for an opening that may never come.

You spend an evening tailoring an application, and nobody on the other side is looking for you.

What do principal data scientist jobs pay?

Across the postings here that list pay, the median is about $209,000 a year. About 4 in 10 of these postings list a pay range; the rest show an estimate, marked as one.

How many principal data scientist jobs are there?

At our last count there were about 170 open postings from about 110 employers. The list on this page is live, so the count above it is the current one.

How does Enhancv spot a ghost job?

Every posting goes through five checks: how long it has been up, whether a salary is posted, what employees say about the company, how specific the description is and whether it lists real requirements. Each job shows the checks it passed and the ones it didn't.

How fresh are the job postings?

Enhancv checks postings every hour, and every job shows how long ago it went up. Most hires happen within 30 days of posting. A listing that's been open for two months raises its ghost job risk.
