Senior Software Engineer

We are looking for a Senior Software Engineer to join the Device Services team within the Growth Engineering organization. The Device Services team owns a collection of high throughput, low latency services responsible for device metadata management, device authentication, and critical client bootstrap workflows. These services are among the earliest systems invoked during application startup and play a foundational role in establishing device trust, enabling access, and supporting seamless user experiences across SiriusXM products.

Responsibilities

• Design, build, operate, and evolve highly available services responsible for device identity, authentication, metadata management, and device lifecycle workflows.
• Develop low latency, high throughput systems that sit on the critical path of client application startup and access flows.
• Collaborate with engineers across User & Identity, Vehicle Services, Client SDK, Platform, and Data Engineering teams to deliver reliable end to end experiences.
• Drive software quality through thoughtful design reviews, code reviews, testing strategies, and operational best practices.
• Investigate production issues, perform root cause analysis, and continuously improve system reliability, observability, and performance.
• Participate in architecture discussions and help shape the future evolution of SiriusXM's device trust and authentication platform.

Qualifications

• 5+ years of professional experience.
• Experience building backend systems in Scala, Java, Kotlin, or similar JVM languages.
• Experience designing and implementing RESTful web APIs in an enterprise setting.
• Deep understanding of the software development lifecycle, including the use of source control, CI/CD and various testing approaches.
• Deep distributed systems knowledge, having supported multiple high throughput systems in a production setting.
• Experience with AWS in a production setting, preferably having leveraged offerings for compute, databases, storage, containers, and serverless technologies.
• Experience with asynchronous programming models, ideally those that support high throughput systems running on the JVM in a production setting.
• Pragmatic approach to weighing engineering tradeoffs versus business needs.
• Persistent sense of curiosity to understand why something is and needs to be.
• Accountability and a sense of extreme ownership that doesn't end after the system is deployed to production.
• Excellent written and verbal communication skills.
