Tatari is on a mission to revolutionize TV advertising. Founded in 2016 to help transform the antiquated world of TV advertising through the intelligent application of AI and machine learning, Tatari helps some of the world’s fastest growing brands including Chime, Calm, Tecovas, Manscaped, Saatva, and Liquid I.V ., reach their customers using linear and streaming TV ads. Our platform combines sophisticated media buying with proprietary analytics to turn TV advertising into an automated, digital-like experience, enabling businesses of any size to advertise on TV.

We're a late-stage AdTech company with strong internal alignment on security, a recently attained SOC 2 Type II attestation, and a clear mandate to mature our security and privacy posture.
We're looking for the right leader to make it happen.
The Role:
You'll lead our existing Security Engineering team, reporting to the SVP of Engineering and work closely with Engineering leadership to develop a deep understanding of our AWS-based SaaS platform and operational environment, then build and execute the roadmap to meet, and exceed, industry security standards.

Lead our Security Policy Advisory Group and develop internal policies, external-facing documentation, and security training
Partner with Legal on our privacy program as it evolves to meet AdTech-specific obligations (CCPA and other US state privacy laws)
Partner with Engineering teams to enable seamless integration of security best practices throughout the development lifecycle
Own customer-facing security: questionnaires, due diligence, compliance attestations, and security review calls
Report up to exec staff and board on posture, incidents, and program maturity
Manage relationships with external cybersecurity vendors
Qualifications:
Meaningful time leading information security teams at a high-growth SaaS company
Strong AWS and Kubernetes security expertise (IAM, networking, data protection, and threat detection)
Led incident response, including stakeholder communication and post-mortems
Built or significantly scaled a security risk management program
Track record of hiring, developing, and retaining security engineers
Broad knowledge across application, infrastructure, and corporate security, with deep expertise in multiple areas
Succeeded in leading security programs through SOC 2 and additional frameworks
Hands-on use of AI in security workflows (threat detection, vulnerability management, security automation), including working knowledge of how LLMs introduce new attack surfaces
Industry-recognized security certifications (e.g., CISSP, CISM) are a plus
Benefits:
Total compensation ($200,000-$250,000)
Equity compensation
Health insurance coverage for you and your dependents
401K, FSA, and commuter benefits
$150 monthly spending account
$1,000 annual continued education benefit
