Staff / Senior Machine Learning Engineer (LLM), AI Lab

Companies that struggle to manage hundreds of millions of dollars in spend because of decades-old software experience slower growth and more roadblocks to innovation. It may sound like an obvious problem, but it’s also a widespread one–and businesses are desperate to solve it.

Our cofounders started Zip in 2020 to address this seemingly intractable problem with a purpose-built procurement platform that provides a simple, consumer-grade user experience. Within just a few short years, Zip created the procurement orchestration category and developed the leading solution in this $50B+ TAM space. Today, leading companies like Instacart, Anthropic, Sephora, Discover, Reddit, and Lyft rely on Zip to manage billions of dollars in spend.

We're a fast-growing team that helped scale category-defining companies like Airbnb, Facebook, Salesforce, Apple, and Google. With a $2.2 billion valuation and $370 million in funding from Y Combinator, BOND, DST Global, and CRV, we’re focused on developing cutting-edge technology, expanding into new global markets, and—above all–driving incredible value for our customers. Join us!

Your Role
