Senior Product Security Engineer

About Sonos

At Sonos, we create the world’s leading sound experiences. Our products span connected speakers, mobile applications, and cloud services — a technically diverse ecosystem where security is built into every layer.

We’re looking for a Senior Product Security Engineer to help operationalize security practices across our engineering organization. This is an execution-focused role: you’ll build the systems, integrate the tooling, and partner directly with product development teams to make secure design and development a consistent practice at scale.

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.

Security tooling and CI/CD integration

• Deploy and operationalize SAST, SCA, secrets scanning, DAST, and SBOM generation across engineering workflows

• Integrate security tooling into CI/CD pipelines in partnership with Engineering Productivity teams. Ensure tooling produces high-signal, low-noise output that engineers engage with.

Security testing and penetration testing

• Define scalable security testing practices across cloud, mobile, web, and connected devices

• Scope, coordinate, and interpret results from third-party penetration testing engagements, including IoT and firmware assessments. Translate findings into clear remediation plans and track them through to closure.

Threat modeling and secure design

• Support and scale threat modeling across cloud, mobile, and embedded domains including device-cloud-mobile trust boundaries

• Provide practical secure design guidance throughout the SDLC — automating the groundwork wherever possible.

Vulnerability response and compliance

• Support vulnerability intake, triage, and coordinated disclosure processes. 

• Partner with compliance and legal stakeholders to ensure security practices are auditable and regulatory-aligned

Automate and scale security practice

• Build and extend AI-powered tooling that encodes security guidelines as agent skills

• Replace static security documentation with automated workflows that embed security practice directly into engineering teams

What You’ll Bring

• 4+ 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: SAST, SCA, DAST, secrets scanning, or similar

• 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 and working with the results; experience with IoT or embedded device assessments is a strong plus

• Experience working with IoT products, connected devices, or embedded systems is preferred but not required
   

​Why This Role Matters

Sonos is in the transition from defining product security practices to executing them at scale. The tooling decisions are largely made, the strategy is set, and the regulatory requirements are real. What’s needed now is an engineer who can make it all work in practice — across cloud, mobile, and embedded domains — in a way that developers actually adopt.

This role directly shapes:

• How securely Sonos products are built — not in theory, but in day-to-day engineering practice

• Sonos’ ability to meet EU Cyber Resilience Act requirements, including PSIRT readiness and vulnerability reporting obligations

• The engineering team’s confidence in their security posture, from SBOM generation to penetration test outcomes

• The scalability of a small Product Security team supporting a large, distributed engineering organization
