• Over time:
  • Take ownership of specific editor features or subsystems
  • Help shape how we migrate legacy code to modern patterns
  • Improve performance and reliability of the editor
  • Mentor other engineers through pairing and feedback

Qualifications

• 5+ years shipping frontend features in production web apps
• Solid JavaScript fundamentals and TypeScript experience

• Comfortable navigating legacy code (AngularJS, jQuery, or similar)
• Can write tests and debug across browsers
• Understands HTML, CSS, and browser behavior deeply
• Experience of using AI Agents and implementing and building AI tools and Agents

Requirements

• You default to shipping incremental improvements over big rewrites
• You ask good questions when requirements are unclear
• You balance code quality with business needs
• You're comfortable working in codebases that aren't perfect
• You can explain technical tradeoffs to non-engineers

Nice to Haves

• Experience with visual builders, editors, or drag-and-drop UIs
• E-commerce or SaaS product experience
• Have migrated legacy apps to modern frameworks
• Familiar with microfrontends or modular architectures

What Success Looks Like

• First 30 days:
  • Ship at least one meaningful improvement to the editor
  • Understand the editor's architecture and key flows
  • Comfortable navigating both legacy and modern code
• First 60 days:
  • Independently own and ship medium-sized features
  • Provide helpful code reviews to the team
  • Identify and propose improvements to editor code or workflows
• First 90 days:
  • Go-to person for specific editor subsystems or components
  • Lead a refactor or quality improvement initiative
