Software Engineer, Security

We’re looking for a Senior Software Security Engineer to own security across our enterprise SaaS platform – from the design of our deployed applications to the compliance programs that earn the trust of large brands. We handle sensitive social and customer data at scale, and our customers expect enterprise-grade security and rigorous proof of it.

As the first Security engineer, you’ll have outsized ownership. You’ll secure the products we ship, lead the compliance initiatives that unlock enterprise deals, and build the security foundations the rest of the engineering team relies on as we grow.

What You’ll Be Doing

• Own the security of our deployed applications, including threat modeling, secure design reviews, and finding and fixing vulnerabilities across our services and AI infrastructure
• Lead new compliance initiatives (SOC 2, and frameworks like ISO 27001, GDPR, and CCPA as we scale), establishing the controls, policies, and evidence to back them
• Own the security side of the sales cycle: complete customer security questionnaires, support enterprise security reviews, and act as our expert in vendor assessments
• Build and run our vulnerability management, secrets management, identity and access, and security monitoring practices
• Manage third-party risk and our penetration-testing program

• 5+ years in security engineering, application/product security, or a related role at a software company
• Strong application and cloud security fundamentals; able to reason about the security of real production systems and AI workloads, not just policy
• Hands-on experience leading or operating a compliance program (SOC 2, ISO 27001, or similar) end to end
• Solid programming skills to build security tooling and automation, and to work credibly alongside engineers
• Comfortable operating in fast-moving startup environments with high ownership and autonomy

Bonus Points

• Experience establishing a security and compliance function at an early-stage or rapidly scaling SaaS company
• Familiarity with AWS, Pulumi, Postgres, ClickHouse, Turbopuffer, or Temporal

• Competitive compensation and early equity
• Health, vision, and dental benefits plus 401(k) match
• Clear career growth opportunities as the company scales
• Free lunch in the heart of University Ave. in Palo Alto
• Deep exposure to cutting-edge AI tooling and the opportunity to shape how brands use it
• A collaborative, ambitious team defining a new category of AI-native marketing infrastructure
