Principal Software Engineer, Platform in London

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it.

Vanta is transforming how companies build and scale trust. As a Principal Engineer, you'll define the golden path for frontend development across the organization—establishing patterns, standards, and systems that enable our product engineering teams to ship faster while maintaining the highest quality.

While Vanta has strong backend engineering practices, our frontend capabilities are still maturing. This is your opportunity to establish what "frontend good" looks like at Vanta: defining best practices for data layer architecture, state management, testing frameworks, and design systems. You'll work closely with our AI Developer Experience team on cutting‐edge AI tooling and agentic feedback loops for AI‐generated frontend code—ensuring our AI‐assisted development maintains quality and consistency.

You'll operate across multiple teams within both Platform and Product Engineering, especially our Design Systems and Frontend Platform teams to influence engineering‐wide standards. This is a hands‐on role where you'll embed with teams to solve complex problems, write code alongside engineers, and zoom out to write strategic documents for executive audiences. You'll partner directly with the Head of Platform Engineering to drive operational excellence and technical strategy for frontend at Vanta.
