SUMMARY We're seeking a Security Engineer II with a strong focus on automation and SaaS security. This role is ideal for someone who enjoys solving security problems with code — building integrations, automating processes, and improving how security operates at scale. The ideal candidate combines deep SaaS security experience with strong Python development skills and a practical mindset for building durable automation that enables detection, response, and configuration management at scale. You don't need to come from a pure software engineering background, but you should be comfortable writing and maintaining production-quality Python and working directly with APIs. A significant portion of this role involves designing and owning automation that reduces manual effort, improves visibility, and strengthens security controls across our SaaS ecosystem. This is a hands-on, highly collaborative role on a small team that values ownership, technical curiosity, and strong interpersonal skills. WHAT YOU’LL DO Design, build, and maintain automation and integrations that collect security-relevant telemetry from SaaS applications, identity providers, and internal systems. Partner with security analysts to enable SaaS detection and response through high-quality log ingestion, normalized data, and reliable integrations. Assist in building SaaS-specific detection rules and integrations that improve alert attribution and context.

Integrate with SaaS application APIs and event streams to support monitoring, alerting, and automated remediation. Implement and support strong authentication and authorization controls across SaaS and internal systems, including SSO, RBAC, and identity lifecycle automation. Collaborate with security engineers to design reusable frameworks, contribute to shared libraries and infrastructure, participate in code reviews, and drive improvements that elevate the quality and reliability of security automation across the platform. Support SaaS onboarding and lifecycle processes by enabling automated security controls rather than manual review. WHAT YOU’LL BRING 5+ years of experience in security engineering or adjacent engineering roles, with a strong focus on SaaS, identity, and cloud-based environments. Strong hands-on experience building automation and integrations using Python, including working with REST APIs, webhooks, and event-driven systems. Experience integrating with and securing SaaS platforms using identity standards such as SAML, OAuth, OIDC, SCIM, and role-based access control.
