We’re working with a high-performing, technology-driven trading firm building mission-critical front office tools used directly by traders in fast-moving markets. They’re looking for a Senior Python Engineer with Qt expertise to help design and deliver the next generation of real-time trading interfaces.

This is a rare opportunity to sit close to the desk, owning the GUI layer of a live trading environment where performance, usability, and speed of iteration directly impact PnL.

• Design intuitive, responsive interfaces for complex trading workflows
• Work directly with front office users to iterate rapidly on features
• Drive performance and usability improvements in latency-sensitive systems

What they're looking for

• Hands-on Qt experience (PyQt, PySide, QML or Qt Widgets)
• Comfortable working in Linux environments

Why apply

• Direct exposure to traders and real business impact (highly technical, collaborative environment)
• Fast feedback loops and ownership of key tools
• Extreme flexibility, as long as you get the work done
• Competitive compensation + strong bonus

We encourage you to apply even if you think you may not currently fit all these requirements – so long as you have proven academics and are willing to work hard and learn, we want to hear from you.
