## Job description

## About OneSchema

More than 90% of all the enterprise data in the world lives in unstructured data, be it spreadsheets, PDFs, or documents. We see an incredible opportunity to be the AI document automation platform to eliminate the manual data entry work that persists across thousands of large enterprises today. We are a fast-growing startup backed by General Catalyst, Sequoia Capital, and Y Combinator. Our customers range from publicly traded companies (Toast, Dayforce) to fast-growing startups (Ramp, Vanta).

We have an ambitious, intense, fast-paced culture at OneSchema. As a rapidly growing venture-backed startup, every team member has the chance to have a major impact on our business. The ability to operate autonomously is an absolute must. With this level of autonomy, you’ll have the chance to learn in one week what it would take months to learn elsewhere.

This role will come with meaningful equity compensation. Our eng culture is in-person, and this role will be based in our SF HQ office 5x per week.

- 3+ years of relevant full-stack software engineering experience
- Comfortable with ambiguity. Excited about wearing multiple hats in a fast-moving environment. Able to hustle to drive results
