Senior/Staff Machine Learning Engineer (Llm)

Zip is tackling the $50B+TAM space to transform the way businesses manage spend. Our co-founders started Zip (YC S2020) because they saw the challenges companies had using outdated 20 year old software to manage hundreds of millions of dollars in spend every year. We invented the world's leading Intake-to-Procure solution to bring a consumer grade user experience to B2B purchasing. And, we're just getting started.
We're a fast growing team that helped scale category-defining companies like Airbnb, Facebook, Salesforce, Apple, Quora, Pinterest, and Square. With $180 million in funding from YC Continuity (Y Combinator), CRV and Tiger Global, we're valued at $1.5 billion in just 3 years. In today's economic climate, the value we offer our customers is more critical than ever and our business is accelerating. We're growing quickly and need your help!
