About this role

The Firefox Mobile UX team works on products and services that keep the Internet open and accessible for all. We are a global mission-driven organization and we strive to put people’s  needs at the core of everything we do. 

As a Senior Product/UX Designer with strong skills in visual and interaction design, you will work as part of a fully remote cross-functional team. You will collaborate with other designers, content designers, and user researchers to craft new experiences in our mobile browser products. You will also have the opportunity to grow as a product designer to tackle more sophisticated, cross-platform design problems that reach a global audience.

In this role, you are also responsible for: 

  • Crafting unified native app experiences across Android and iOS while respecting Material and HIG conventions.
  • Solving defined design problems - starting with existing Firefox research and data through exploration, iteration, feedback from partners, and evaluative testing.
  • Delivering production-ready specs and following the work through implementation, release, and post-release with your cross-functional team.
  • Collaborating with other team members including Product and Content Designers, User Researchers, Product Managers, and Engineers.
  • Contributing to the Firefox mobile design libraries and aligning with the Firefox design system.
  • Being an active UX team member by providing design feedback and advancing team processes and practices.
  • Advocating and incorporating best design practices for inclusive design.


We are seeking a team member who:

  • Has a portfolio with at least one mobile app example that demonstrates the ability to solve user problems and create design deliverables for product development
  • Has at least 2 or 3 years of experience in product development and UI/UX design
  • Has experience creating production-ready interfaces that demonstrate a firm grasp of visual design principles like composition, hierarchy, balance, color, etc.
  • Experience designing for BIPOC communities is a huge plus
  • A degree in design is not required. If you don’t meet 100% of the qualifications above we still encourage you to apply!


As a successful Sr. Product/UX Designer, you are able to:

  • Advocate for products that are accessible, inclusive, and reflective of the needs of diverse audiences.
  • Demonstrate how your designs address business goals and user needs.
  • Collaborate with people on other teams --  including product management, user research, data science, and engineering -- to develop products.
  • Manage competing priorities and act on decisions in the face of ambiguity.
