As a Senior Staff Engineer, Product Security, you will be the primary technical lead for the Product Security domain at Faire, setting the long-term technical direction for application security. This involves establishing scalable, developer-friendly frameworks and principles that enable secure development across all product areas. You will lead the design and implementation of high-impact, reusable frameworks for critical security use cases such as authentication, authorization, secrets management, and data protection. A core aspect of this role is architecting and automating security controls within development and deployment pipelines, enabling proactive prevention, detection, and remediation of vulnerabilities at scale.
Collaboration is key, as you will partner with senior engineering and platform leaders to influence system design, threat models, and architecture decisions, thereby strengthening Faire's overall security posture. Driving strategic cross-functional initiatives, you will work with Platform, Infrastructure, Risk, and Compliance teams to integrate security deeply into the technical and operational foundations.
