  • Evangelize the design system through meeting and mentoring the teams that consume it, as well as presenting architectural concepts and decisions.
  • Oversee the open-source ecosystem, reviewing pull requests and assisting external teams with contributions.
  • Work closely with UX designers to build richly interactive components for web and mobile web using a high degree of visual fidelity.
  • Write highly reusable code that can be componentized and easily consumed and extended by other developers.
  • Improve developer experiences and velocity by building better workflows, practices, and tooling for development.
  • Research new and interesting open source and third party software. Document and justify incorporating new software into Monster’s technology stack.
  • Promote UX best practices and processes across the team and help stand up a consistent suite of UX tools and libraries.
  • Be an awesome team-mate and mentor. Engage with the rest of the UX development and design team, as well as other external teams on various projects.


  • 7+ years’ experience in UI development, Frontend development, or comparable roles.
