About the Opportunity

Interested in working on a green-field project with the opportunity to build a new SaaS platform from scratch? We are seeking a highly capable Full-Stack Engineer who can independently develop a platform from end-to-end.

The ideal candidate acts like an owner - is responsible for product outcomes beyond code, takes pride in their work, speaks their mind loudly and clearly, and works with passion.
