Senior Back End Engineer (Ruby on Rails & GO)

<div class="content-intro"><p><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 12pt;">At PrizePicks, we are the fastest-growing sports company in North America, as recognized by Inc. 5000. As the leading platform for Daily Fantasy Sports, we cover a diverse range of sports leagues, including the NFL, NBA, and Esports titles like League of Legends and Counter-Strike. Our team of over 550 employees thrives in an inclusive culture that values individuals from diverse backgrounds, regardless of their level of sports fandom. Ready to reimagine the DFS industry together?&nbsp;</span></p></div><h2><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 18pt;">Overview</span></h2> <p><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 12pt;">At PrizePicks, we are changing the game in daily fantasy sports. We are a passionate team of innovators dedicated to creating a best-in-class experience for our members. Our engineering team builds and scales the platform that powers our explosive growth from real-time contest engines to the services that handle millions of daily transactions. We are looking for a talented and driven Senior Software Engineer to join our <strong>Back Office</strong> team and help us build the internal platform that powers every operation at PrizePicks.</span></p> <h2><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 18pt;">Job Summary</span></h2> <p><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 12pt;">We are seeking an experienced Senior Software Engineer fluent in both <strong>Ruby on Rails and Go</strong> to join our Back Office team. Back Office is the internal operational platform used by Game Ops, Trading, Member Operations, and Risk teams to configure projections, trade lines, manage members, review risk, and monitor live scoring — all of which directly shapes what millions of members see in the app.</span></p> <p><span style="font-family: tahoma, arial, helvetica, sans-serif; font-size: 12pt;">In this role, you will design and build backend services that span our Rails monolith and our growing ecosystem of Rails and Go microservices. You will work across existing as well as new services being carved out as we migrate toward a microservices architecture. You will tackle high-scope, complex technical problems, own features end-to-end, and mentor engineers on your team. This is a role for someone who is equally comfortable extending a mature Rails codebase and greenfielding a new Go service, and who is energized by the challenge of a platform in active, deliberate evolution.</span></p> <h2><span style="font-family: tahoma, arial, helvetica, sans-serif;
