About the role

A global ad tech business in the Bay Area is seeking an Applied Data Scientist III to design algorithms for auctions and pricing. The ideal candidate will have 5.5–7 years of experience in applied science, strong skills in Python and large-scale data systems, and a PhD in a relevant field. You'll own the model lifecycle and collaborate closely with engineering teams to directly influence real-time marketplace behavior. This full-time role offers a hybrid work environment with competitive salary and benefits.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
