We maintain the systems, including our monorepo and other key FE repositories, that enable hundreds of engineers to build and ship high-quality, modern frontend applications. Our mantra is: "Create a development experience that people will miss when they leave". FEP drives platform-level initiatives, sets best practices in frontend development, and elevates engineering velocity and experience across Carta, ensuring our applications reflect modern standards and scalable development techniques.

The Interview Process Carta follows a standard tech startup interview process, where you will meet with a recruiter and hiring manager first. We’ll then ask you to show off your skills with a real-world take‑home exercise (we do not do LeetCode‑style interviews, no one will quiz you on writing a doubly-linked list) and virtual interviews. During the process, you can ask questions to people across different parts of the Frontend Platform team to learn what kind of work we do and how it lines up with your interests.
