Senior Software Engineer, Core Developer Experience

Bubble is an AI visual development platform that empowers users to create software without traditional coding. The Senior Software Engineer on the Developer Experience Pod will lead technical projects to enhance how engineers build and ship code, focusing on modernizing tools and improving developer productivity.

Responsibilities:

• Migrating off legacy frameworks and introducing modern frontend tooling
• Upgrading shared libraries and improving support for our internal design system
• Reducing test suite runtime and improving reliability of developer-facing tests
• Optimizing the local development loop, including build, bundling, and hot reload times
• Investigating and resolving sources of frontend performance regressions in the Editor
• Defining standards and building frameworks that other Core teams can adopt to increase consistency and speed
• Staying up to date with modern AI tools and incorporating them into the developer workflows

Requirements:

• 5+ years of professional software engineering experience, with a history of delivering high-impact technical projects
• Strong proficiency with modern frontend frameworks (TypeScript, SolidJS/React, etc.) and the ability to work confidently across the stack
• Deep experience with developer tooling — build systems, bundlers, testing frameworks, package managers, and CI/CD pipelines — and a passion for improving how engineers work day to day
• Proven ability to modernize large, complex codebases, including migrating frameworks, upgrading dependencies, and designing for long-term maintainability
• Experience organizing and leading projects that span multiple engineers, ensuring alignment, execution, and measurable outcomes
• Strong problem-solving skills, balancing pragmatic short-term improvements with strategic, scalable solutions
• Collaborative and clear communicator who partners effectively across teams and mentors engineers at different levels
• Adaptable and curious — you proactively identify inefficiencies, dig into root causes, and design solutions that scale beyond your own team
