Be at the forefront of AI security: evaluate, implement controls for, and secure our evolving suite of AI-assisted and agentic internal tools (e.g., Claude Code, MCP servers, LLM-driven automation).
Lead incident response for security findings, including in-depth investigation of authentication anomalies, comprehensive access log reviews, and data analysis using tools like Athena, CloudTrail Lake, and Superset.
Drive security by contributing significantly to Infrastructure-as-Code (Terraform) for defining security controls, managing identity provisioning, and ensuring compliance-relevant configuration and monitoring.
Collaborate with engineering and customer-facing teams to design and ensure secure network and cloud deployments for our enterprise customer environments.
Stay ahead of the curve: research emerging cloud-native and AI security capabilities (including advanced AI-enabled attack techniques) and translate cutting-edge findings into actionable controls and internal best practices.
Elevate our security posture through clear documentation, crafting comprehensive runbooks and playbooks to scale security practices and knowledge across the organization.
We're looking for a security expert with:
Proficiency in scripting and automation with 3+ years of experience in Bash or Python.
Deep, practical expertise with a major cloud provider (AWS, Azure, GCP, or OCI).
Solid experience with Infrastructure-as-Code (Terraform is a strong plus) and robust identity/access management platforms (e.g., Okta, Azure AD).
Demonstrated exposure to at least one of the following specialized areas: OAuth/token architecture, security for AI/LLM-assisted tooling, or agentic workflow design.
A strong foundation in operating systems and networking fundamentals.
A Bachelor's degree in Computer Science or a related field, or equivalent practical experience that demonstrates your capability – we value experience over degrees.
