At Sonos, our IT Infrastructure team builds and maintains the technical foundation that every team at the company depends on, from cloud platforms and data services to developer tooling and network reliability. The Senior Infrastructure Architect plays a central role in shaping how that foundation evolves, translating business needs into reusable, scalable infrastructure designs that become the standard blueprint for teams across the company. This role sits at the intersection of architecture, engineering, and strategy, serving as part designer, part escalation point, and part mentor, and it directly enables Sonos' ability to build and ship great products.

What You'll Do

• Own the end-to-end design of cloud and on-premise infrastructure, producing reusable blueprints that serve as the standard across all teams requiring infrastructure to support their applications.

• Define and drive the Infrastructure as Code (IaC) strategy for the IT organization, establishing standards for tooling and practices across teams.

• Partner with Network Engineering to ensure network designs align with infrastructure standards, and collaborate with stakeholders in Product Software, Product Hardware, Security, and IT to align architecture with business requirements.

• Define Standard Operating Procedures (SOPs) for software and hardware installations, ensuring infrastructure is tested for resiliency and ready for service transition to Global Operations.

• Automate and improve development and release processes in partnership with the Quality Engineering team, and identify broader automation and process improvement opportunities across Infrastructure and Network Engineering.

• Identify and evaluate technology innovations, engaging with business stakeholders to assess requirements, feasibility, and value, including emerging AI tooling and platforms.

• Act as an escalation point and subject matter expert for operations teams, supporting incident resolution and providing architectural guidance on complex or ongoing production issues.

• Mentor the Global Operations team in Incident Management, Change Management, Release Management, and troubleshooting practices, and support less experienced engineers on performance tuning and availability management.
