DevOps QA Engineer - Risk & Trading

About Sleeper

Sleeper is a rapidly growing platform for sports fans with messaging and gameplay at its core. We’re reimagining how fans interact with sports—from season-long fantasy leagues to daily gaming formats—with a seamless, social-first experience that puts the user first.

Behind the scenes, Sleeper is powered by a modern, scalable tech stack. While much of our backend is Elixir-driven, this role sits at the intersection of Python-based data services, our Elixir backend, Google Cloud Platform (GCP), and distributed analytics infrastructure. You’ll help us ensure our trading systems are robust, our pricing is real-time, and our risk engines are resilient.

The Role

We are seeking a DevOps/QA Engineer with a passion for automation, quality, and observability to join our Risk & Trading team. You’ll work on critical infrastructure and testing pipelines that power Sleeper’s real-money gaming experience—helping to scale pricing engines, maintain system reliability, and build the tooling to detect anomalies before users ever feel them.

What You’ll Be Doing

• Design, build, and maintain CI/CD pipelines for trading and pricing services (Python & Elixir).
• Develop infrastructure as code (Terraform, GCP-native tools) for deploying and scaling trading infrastructure.
• Build automated QA pipelines to test settlement, pricing accuracy, and edge-case simulations across sporting events.
• Work closely with engineers and data scientists to validate data integrity and model behavior in production.
• Monitor system performance and implement observability tools (Prometheus, Grafana, etc.) to identify and mitigate production risks.
• Create fault-injection tests and run load-testing simulations that replicate real-world market stress.
• Participate in post-mortem reviews and help create actionable feedback loops for continuous improvement.
