Given our stage, we’re seeking versatile engineers comfortable contributing across the frontend, the backend and the data., We’re looking for exceptional engineers, and we set the bar high on purpose. In return, you’ll get real ownership from day one, products used by millions of people, a team that ships in days rather than quarters, a modern stack with top-tier tooling, and colleagues who will push you to grow.

Please indicate your years of experience on the application form.

7+ years of professional experience building SaaS products or data-heavy platforms.

High proficiency in TypeScript and Node.js, and in modern web frameworks (React, Next.js…).

Solid understanding of data modeling for analytics and for visualizing large volumes of data.

A privacy-aware approach to handling sensitive data, such as aggregation and anonymization.

Experience with WebGL or GPU rendering is a plus.

Comfortable working closely with backend and data teams across a polyglot stack is a plus.

Knowledge of infrastructure (Bazel, GCP, Kubernetes) is a plus.

Passion and experience building great products. We’d love to hear about things you’ve shipped!, AI is part of how we build every day. We’re looking for engineers with a real grasp of these tools, who use them to multiply their output and not to make up for missing expertise.
