The Problems You'll Solve

At Carta, our employees set out on a mission to unlock the power of equity ownership for more people in more places. We believe that the problems we solve today unlock the opportunities of tomorrow. To do this well, we must continuously raise the bar on software quality—without compromising developer velocity.

As a Senior QA Automation Engineer II, you won’t just be writing tests—you’ll be a force multiplier for quality across the engineering organization. You’ll work across multiple product teams to drive a strategic shift: from QA as a safety net to quality as a shared responsibility, embedded into every part of the development lifecycle.

You’ll lead efforts to identify critical coverage gaps, implement and scale test automation frameworks, and roll out self-service tools that enable developers to write, run, and promote tests with confidence. You’ll partner closely with embedded QAs, developers, and platform teams to shift QA towards an enablement model that amplifies impact across teams.

You’ll help pilot new ways of working that reduce manual effort, catch defects earlier, and improve the signal-to-noise ratio in our CI pipeline—whether through smarter automation, better tooling, or new AI-integrated approaches to test reliability and triage. Ultimately, your work will help Carta move faster without sacrificing confidence—by making automated quality an invisible but essential part of our software delivery process.

The Team You'll Work With

The QA Organization consists of ~15 QAs who work closely with our Product, Engineering, and Support teams.
