Job details

BettingJobs is working with a fast-growing sports betting technology business to recruit a Senior Software Engineer for its Trading Technology team. You'll build the backend engines behind real-time trading, risk management and core platform services — systems where low latency, high throughput and reliability are critical — as well as the React front-ends that surface them.
