Lead Frontend Engineer - Gatsby

About Gatsby

Gatsby is modernizing how enterprises manage executive relationships and event workflows. Used by leaders in venture capital, finance, enterprise, and nonprofits, Gatsby replaces disjointed planning tools with a streamlined, intelligent event CRM platform that powers everything from personalized invites to real-time guest tracking.

Gatsby customers organized over 1,000 events in 2023 and sent 125,000+ communications through the platform — growing 10x year-over-year. With an ambitious roadmap ahead, we’re expanding from events into broader relationship workflows like recruiting, sales, and executive communications.

About The Role

We’re looking for a Lead Frontend Engineer to shape the future of our core product experience. This is a high-impact role where you’ll drive architecture, set engineering standards, and deliver elegant, high-performance interfaces that power mission-critical workflows for our customers.

  Lead the development of our component system and UI tooling (e.g., Storybook), helping us scale design consistency and speed

  Set the standard for frontend excellence — driving code quality, testing practices, and system performance

  Mentor fellow engineers, share knowledge, and build a strong frontend culture

  Balance execution speed with technical debt management, scalability, and maintainability

  Work cross-functionally to scope projects, prioritize enhancements, and improve developer velocity
