If you embrace unconventional challenges, are unafraid to think differently and are driven to make an outsized impact, you’ll thrive here at Zopa, so join us, and make it count. Want to see us in action? Follow us on Instagram @zopalife
The engineering challenge
Our Software Engineers don't just write code, they solve real financial problems for millions of customers. You'll work on distributed systems processing thousands of transactions daily, build resilient services that handle people's money, and create experiences that make traditionally complex financial products feel simple.
By bringing together next-gen technology and the finest live data available, Genius Sports is enabling a new era of sports for fans worldwide, delivering experiences that are more immersive, interactive and personalized than ever before. Learn more at geniussports.com. The Role You will join one of our established high-performing teams within the Betting division, as we invest in our core and future Betting products. You will be focusing on the delivery of technical and product-focused initiatives, to expand and scale up our industry's leading Sportsbook and Risk Management products. One example is our Advanced Risk team, who were set up to challenge conventional wisdom about risk management for sports betting operators. Using new measures of liability that take account of correlations between different markets on an event, and by monitoring betting patterns from the moment an event is opened for betting, we apply margins asymmetrically in a way that helps operators to make higher profit margins, reduce volatility and improve customer experience with greater uptime and fewer rejected bets. Our software provides customers with a new level of flexibility over the way they manage their Sportsbooks to meet their financial objectives. Smart algorithms allow decisions about bets to be taken quickly at scale while enabling close control when desired, reminiscent of earlier days of sports betting. How will you work?
