At Development Seed, we design solutions to help our partners solve global problems. We believe in designing for humans, and our commitment to user-driven research sets us apart. Our interfaces are in production at organizations like NASA, the World Bank, and the Red Cross.

We’re looking for a new team member who can lay beautiful, intuitive UI solutions. As UI/UX designer, you will play a leading role in the product development process, engaging directly with users to understand their needs, articulating your design vision, and building well-structured HTML/CSS. You’ll be responsible for creating cohesive style guides and ensuring that a consistent design language is applied across products. You will join a talented team of thirty(-ish) designers, engineers, and data experts, where you will own the visual component for a wide range of our tools, graphics, and maps.

This is a full-time position, based in Washington, DC.


  • Care about users, and strive to understand how your work impacts them through user-testing.
  • Communicate clear design direction, verbally and through mock-ups, wireframes, and other methods.
  • Write clean HTML and CSS, and understand the importance of semantic, accessible markup.
  • Give and solicit critiques from other designers in order to improve your craft.
  • Continually challenge yourself to pick up new tools and workflows.

  • Designing user interfaces
  • Current UI/UX best practices
  • HTML and CSS
