SiriusXM and its brands (Pandora, SiriusXM Media, AdsWizz, Simplecast, and SiriusXM Connect) are leading a new era of audio entertainment and services by delivering the most compelling subscription and ad-supported audio entertainment experience for listeners -- in the car, at home, and anywhere on the go with connected devices. Our vision is to shape the future of audio, where everyone can be effortlessly connected to the voices, stories, and music they love wherever they are.

We are proud to have launched a new state-of-the-art technology facility in Dublin, Ireland. The Dublin-based team plays a critical role in our continued digital transformation and will function as a center of excellence for SiriusXM’s global Product and Technology organization.

SiriusXM’s new Dublin facility will comprise a workforce primarily focused on software development, automotive technology and engineering, AdTech, data science, and analytics. Talent based in the new technology hub will be charged with developing and implementing best-in-class standards for high-quality, scalable software deliveries for SiriusXM’s streaming and in-vehicle audio entertainment platforms.

How You’ll Make An Impact

SiriusXM’s Services and Platform Engineering organization is growing in Dublin! 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.

Our team operates services that verify the authenticity of SXM-generated chipsets, manage device lifecycle information, and publish critical device-related events used throughout the SiriusXM platform. The systems we build and operate serve tens of millions of listeners and connected devices across North America and are designed for exceptional reliability, scalability, and operational excellence.

What You’ll Do

• 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.

What You’ll Need

• 5+ years of professional experience.
• Experience building backend systems in Scala, Java, Kotlin, or similar JVM languages; experience with Scala and functional programming is highly desirable.
• 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.
