Senior Software Engineer (.NET)

By bringing together next‑generation 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.

The Role

You will join one of our established high‑performing teams within the Betting division, 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, which challenges conventional wisdom about risk management for sports betting operators. By using new measures of liability that account for correlations between different markets on an event, and by monitoring betting patterns from the moment an event opens for betting, we apply margins asymmetrically to help operators achieve 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 enable decisions about bets to be taken quickly at scale while allowing close control when desired.

How will you work?

Join a specially formed, highly skilled team delivering an innovative and intelligent product. As part of a multi‑disciplinary Agile squad of Software Engineers, Data Scientists, QA Engineers and a Product Manager, you will work closely and follow the principles of continuous delivery and empowered, high‑performing teams. We operate in a squad model to focus on the business top priorities while maintaining strong ownership of your team’s domain. If you are looking to tackle hard problems with smart solutions, collaborate with astute engineers, and deliver high‑calibre code with an autonomous and performance‑focused approach that supports success, delivery and quality, then this is for you.

As a Senior Software Engineer 1 (SR1), you and your team will build highly distributed, real‑time, dynamically scaling systems using modern CI/CD pipelines and cloud infrastructure. You will be responsible for innovating, architecting, delivering and maintaining an industry‑revolutionising product and will lead the execution of multi‑sprint features or systems with measurable business impact. We lean on your technical expertise and your pragmatic approach to problem solving, working in a team that prioritises Agile delivery and continuous improvement. You will have a data‑driven, evidence‑based mentality, comfortable with continuous experimentation and validation.
