About QFEX

QFEX is the 24/7 exchange for traditional financial markets.

We let you trade US equities, commodities and FX pairs with (or without) leverages of up to 100x. On QFEX, UX comes first: brokerless market access, seamless integration with traditional payment rails, and ultra-efficient Perpetual Futures offered over all asset classes. Trading has never been simpler, cheaper or fairer than with QFEX.

Founded by Quants and Engineers from Citadel & Tower Research who saw an opportunity to make markets how they always should have been, QFEX will eventually replace the entire $100 billion exchange and clearing industry.

Mission

QFEX is building the most delightful retail trading experience that’s ever existed. We need a visionary UI/UX designer to work alongside our product team and take the product from feedback to fruition. This is an incredible opportunity to work alongside an elite, well-funded team of builders from some of the biggest financial companies in the world (Citadel and Tower Research Capital) and change the course of financial history.

  • Familiarity with HTML/CSS and modern JavaScript frameworks (e.g. React) to collaborate deeply with engineers.
  • Track record of scaling design function rapidly and iterating under tight deadlines.

Benefits

  • Lunch allowance and regular company events.
  • The ability to grow alongside some of the best minds in fintech, as well as set standards and culture.
  • Brand-new office near Liverpool Street with top-tier hardware and a stocked kitchen.
  • 25 days holiday + bank holidays.
