About Sonos

Sonos makes the world's leading listening experiences — and the products behind them span a technically diverse ecosystem: embedded firmware, mobile applications, web platforms, cloud services, and partners. If you're looking for an opportunity to apply security principles across technical domains, and work on an outstanding consumer product, this is a great opportunity.

The Product Security team combines modern security tooling, automation, and AI with industry-defining security frameworks and direct development team partnerships. We enable secure-by-design and secure-by-default practices that are a natural part of how engineers work. We’re creating AI-powered workflows that encode security guidelines, automate the groundwork for threat modeling, and replace manual triage with intelligent pipelines. If you think security policy should run in a pipeline rather than live in a document, you'll fit right in.

What You’ll Do

You’ll own the execution layer of product security — the systems, tooling, and processes that make security practice consistent and measurable across cloud, mobile, and embedded engineering domains;

• Partner with engineering teams to identify and manage security risks across the software development lifecycle, from design through deployment

• Integrate and operationalize security tooling across CI/CD workflows, ensuring findings are high-signal, actionable, and lead to practical remediation

• Build automated and AI-assisted security workflows that turn security guidance into repeatable engineering practices and reduce manual effort

• Lead threat modelling across product domains and help teams identify and address risks at key trust boundaries

• Establish repeatable security testing practices using automation and targeted manual assessment

• Coordinate penetration testing and targeted security assessments across relevant product domains

• Support vulnerability intake, triage, remediation, coordinated disclosure, and Product Security Incident Response Team (PSIRT) readiness

What You’ll Bring

• 3+ years in software engineering, application security, or product security

• Experience working directly with engineering teams in modern software development environments

• Hands-on experience implementing and operationalizing security tooling

• Experience integrating security practices and tooling into CI/CD pipelines 

• Experience using AI tools to automate security practices and previously manual activities

• Experience scoping or coordinating penetration testing engagements
