About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Take ownership of new product areas built from the ground up, working across the front end and back end of a web application.

Requirements

What we're looking for

- 4 to 8 years of software engineering experience, already operating at a senior level and seeking broader end-to-end ownership.

- Strong skills in at least one modern programming language, plus readiness to work with TypeScript and React on the front end and Node.js on the back end.

- A strong academic record.

- Ability to work on-site five days a week in San Francisco.

Bonus points
