The Team You'll Work With

The Frontend Platform team is the core infrastructure team that underpins the entire frontend experience at Carta. 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.

• Platform & Scale. You have previously worked on a dedicated platform or infrastructure team at a company with an engineering organization of 100+ engineers.
• Deep React Knowledge. You have a history of advanced contributions to a React-based ecosystem. You are well versed in modern React development paradigms.
  Global Improvements. You have demonstrated leadership in driving platform-level improvements that affect all applications, such as significant page performance gains, build time reduction, or dependency upgrade initiatives.
• Frontend DevOps. You possess a strong command of frontend build and delivery systems, including optimizing bundlers (Webpack/RSpack) and setting up/maintaining CI/CD pipelines (Github Actions, Jenkins, CircleCI).
• 7+ years of professional experience recommended in relevant frontend platform engineering roles.

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 Platoform team to learn what kind of work we do and how it lines up with your interests.
