Working with our Sales and frontend team to build products with the goal of delighting and increasing the success of our users.
Architecting, building, testing, and releasing product-facing features.
Contributing to our side projects and free tools for the education industry.

1-2 years of industry experience in a software engineering role, preferably building a SaaS product. You can demonstrate significant impact that your work has had on the product and/or the team.

Deep knowledge of SQL Databases
Experience with scalable distributed systems, both built from scratch as well as on AWS primitives
Willingness to learn and use new technologies
Extremely data-driven
Ability to debug complex systems
