Our work includes upgrading tooling and libraries, migrating off deprecated frameworks, strengthening support for our internal design system, speeding up testing and bundling, and addressing technical debt that slows down product delivery.Some initiatives we drive directly, while others involve building standards, frameworks, and example implementations that empower other feature teams to adopt best practices. By enabling engineers to work faster and with more confidence, the DX Pod creates leverage across the organization and ensures that Bubble’s engineering culture can scale as our product and customer base grow.About the role:As a Senior Software Engineer on the Developer Experience Pod, you’ll lead technical projects that improve how engineers build, test, and ship code at Bubble.
