About OneSchema

At every company, there's someone whose most painful job is wrangling CSV files in Excel. OneSchema ( makes cleanup of messy CSVs 10x faster (demo). Our product is an embeddable spreadsheet that makes data cleansing and import as simple as a few clicks. We see an incredible opportunity to be the de-facto data transfer platform for all industries that run on CSV files (hint: it’s all of them). We get our customers out of spreadsheets and back to the meaningful, creative work they love.

We are backed by top investors including General Catalyst, Sequoia Capital, and Y Combinator. And as a rapidly growing seed-stage company, every team member has the chance to have a major impact on our business. Compensation is competitive - we expect employees to act like owners and make sure their equity stake reflects that.

Because we are a highly collaborative, close-knit team, our entire engineering team works 5 days per week from our office in downtown San Francisco.

About the role

We’re looking for a full-time Senior Software Engineer. You will go 0 to 1 on new product initiatives as well as scaling our core platform to handle millions of file imports monthly. You will be given a lot of autonomy, and the chance to learn in one week what it would take one month to learn elsewhere. Our stack consists of Ruby, Rust, Typescript, and React. We use Postgres, Redis, and S3 for data storage.

  • You will develop and implement strategies for improving the performance, reliability, and scalability of our platform that supports CSVs with thousands of columns and millions of rows.

  • You will review pull requests, design documents, and architecture decisions to ensure system quality.

  • You will be the primary owner of core product areas and develop domain expertise over those systems. Examples include our in memory Rust data service that executes all of our spreadsheet validations and transforms on massive spreadsheets and our version control system which allows customers to safely build experiences in OneSchema in sync with their deploy processes.

  • You will work directly with the Design, Customer Engineering, and GTM team to understand the customer and make decisions on the product that will lead to a better user experience.
