Staff UX Designer

Jane Street
London

About the Position

We are looking for Staff UX Designers capable of producing elegant design solutions, while also cultivating an environment for sustainable design growth at the firm. You will be placed on one of various teams within our Technology groups, depending on your particular background and focus.

Collaboration amongst teams and users across a wide variety of disciplines is integral to Jane Street, so we're very invested in building an intentional design culture that helps our colleagues do their best work. The interest in partnering with people who bring user experience process and thinking to projects has grown in parallel with the scale of the firm. You will be joining at an inflection point: we are actively growing our design talent to meet the demand.

With direct access to a diverse user community, you will lead initiatives to help your team understand what people need to do their jobs, and apply user research to help scope what products need to be built to address those needs. You will also help teams better understand how to approach user-centred research and how they can deploy these methods early and often during the product life cycle.

Demonstrating design craft is critical to the daily work of this role. As you scope work to be done in partnership with your team, you will sketch, storyboard and prototype possible solutions for better experiences. We will expect you to distil the complex routines of our user communities into approachable design solutions for people of all technical levels, whether they are for an internal team or targeted toward an external audience. Your scope of work will encompass initial conversations with people to learn more about their systems and challenges.

You should be willing to take the time needed to learn about our work and existing processes, while being flexible as we build a design presence. You will offer your insights on UX decisions across your team, advocate for usability testing across other parts of the firm, standardise user research methodologies and further define how our teams can best partner with a design collaborator.

About You

  • Have 5+ years of experience in UX design with a professional portfolio that demonstrates a mastery of distilling challenges people face with their software into feasible solutions (please include a link to this in your resume or elsewhere in your application)
  • Interested in helping our users and passionate about making their lives easier
  • Comfortable working on problems that rarely have clean, definitive answers; happy to make immediate, incremental improvements where there is obvious value
  • Capable of leading design projects across a product life cycle from early conception to launch
  • Invested in unpacking technical details within a new domain prior to deep design work
  • Comfortable sharing ideas and designs early, and rapidly updating them within nebulous problem spaces
  • Enjoy collaborating with a wide range of colleagues with different skillsets and levels of experience; approachable, humble and curious
  • Eager to create a strong design ethos within the firm and to collaborate with colleagues to integrate a design process
  • Fluent in English

If you're a recruiting agency and want to partner with us, please reach out to [email protected].
