Senior Software Engineer, Sportsbook Platform

Role overview

Build and operate backend services and real-time APIs that support sportsbook and casino experiences across mobile and web. You’ll own work from API design through client behavior, partnering closely with mobile and web engineers to keep features reliable under heavy, bursty traffic. The role also includes production operations, technical leadership, and hands-on use of AI coding agents in day-to-day development.

Responsibilities

- Design, scale, and tune APIs and real-time delivery systems, treating schemas as versioned contracts for released clients. - Plan compatible API changes and migrations with iOS and Android teams, keeping client models aligned. - Diagnose production bottlenecks and performance regressions; improve monitoring, alerting, and tracing. - Own features and fixes end to end, including targeted client changes and debugging across server and app boundaries. - Write tests, operate services through release cycles and on-call, and document designs and procedures. - Guide engineering work through proposals, reviews, pairing, and mentorship; use and review AI agent output to production standards.

Requirements

- At least 5 years of software engineering experience, primarily in backend or API systems. - 2+ years designing and evolving APIs used by multiple clients, including versioning and backward compatibility. - Experience building real-time features and operating production services, including on-call and end-to-end releases. - Strong computer science fundamentals, especially distributed systems, algorithms, data structures, and software design. - Ability to investigate performance across CPU, I/O, memory, and latency using techniques such as tracing and load testing. - Daily experience building software with AI coding agents, plus the judgment to constrain, test, and review their output. - Clear technical writing and experience with a server framework; willingness to learn Swift or Kotlin for targeted mobile work.

Nice to have

- Shipped native iOS or Android work; experience with GraphQL, Elixir, or relational databases. - Kubernetes, container operations, background job systems, or messaging infrastructure.
