Senior Security Engineer
$200k - $330kWintermeyer Ventures
About the Role
This is a senior individual contributor role owning application security for a rapidly scaling, multi-tenant AI agent platform that serves enterprise customers. You will sit at the intersection of product engineering and security, embedding secure practices across the full software development lifecycle. The work directly protects sensitive customer data at scale and shapes how a fast-growing AI company builds security culture from the ground up.
What You'll Do
- Design and implement application security controls across a multi-tenant AI platform, including secure coding practices, threat modeling, and vulnerability management.
- Partner closely with product engineering teams to integrate security from design through deployment.
- Build security tooling and automation that helps developers ship quickly while identifying and remediating vulnerabilities fast.
- Lead security code reviews and architecture assessments for new features, with a focus on AI model integration points and customer data handling.
- Respond to security incidents involving application vulnerabilities and drive post-incident improvements.
What We're Looking For
- 4+ years of combined software engineering and hands-on application or infrastructure security experience, ideally at a high-growth company or well-funded startup.
- Strong software engineering foundation, either transitioning into security or already working as an AppSec engineer in a fast-paced environment.
- Practical security engineering experience, not a pure compliance or GRC background.
- Experience with GCP or AWS cloud security.
- Familiarity with security tooling across the stack: SAST, DAST, IAST, container security, Semgrep, or CodeQL.
- Comfort working within Python-based codebases and cloud-native infrastructure (Kubernetes, CI/CD pipelines).
- Strong CS fundamentals, ideally from a rigorous undergraduate program.
- Background as an early or founding security engineer at a VC-backed company is a plus.
- Demonstrated rapid career progression or early promotion is a plus.
Compensation & Benefits
Base salary range: $200,000 to $330,000 USD annually , plus equity. Visa sponsorship is not available for this role.
Location
This role is on-site five days per week in San Francisco, CA .
