About the role

Pinterest is seeking a Principal Engineer to shape the technical strategy for Indexing & Retrieval Infrastructure across Core, Ads, and Shopping. You will drive architecture modernization, mentor engineers, and partner with leaders to deliver high-scale, high-quality candidate generation across discovery surfaces. You will leverage AI to accelerate analysis, design exploration, and platform insights, while maintaining strong focus on correctness, privacy, and operational excellence.

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.
