## Description

Note: This position requires presence in our Bellevue, San Francisco, or San Jose office location 4 days per week; Lambda's designated work from home day is currently Tuesday., Lambda Security protects some of the world's most valuable digital assets: invaluable training data, model weights representing immense computational investments, and the sensitive inputs required to leverage best of breed AI models. We're responsible for securing every byte that powers breakthrough artificial intelligence.

Reporting to the CISO, you'll be a key member of the Enterprise Security team responsible for securing Lambda's SaaS applications, corporate IT infrastructure, identity and access management (IAM), and endpoint ecosystems. Your work will focus on establishing secure-by-default configurations, automating access governance, and protecting corporate environments as Lambda scales rapidly.

You will directly impact the security posture of our enterprise operations by implementing robust Identity Governance and Administration (IGA), hardening corporate SaaS tools, automating joiner-mover-leaver (JML) workflows, and deploying zero-trust network access controls. Leveraging Lambda's hosted LLMs, you'll pioneer AI-driven enterprise security automation-such as intelligent access reviews, automated policy enforcement, and SaaS risk monitoring.

If you're excited about building enterprise security controls that balance strong protection with developer and employee productivity, we want to talk., * Design, deploy, and maintain Identity and Access Management (IAM) architectures, SSO/IdP integrations (Okta, Entra ID), and Privileged Access Management (PAM) across corporate and SaaS ecosystems

 * Automate Joiner-Mover-Leaver (JML) workflows and lifecycle management to enforce least-privilege access and zero-trust principles across all internal tooling
 * Build automated access certification and review tooling to streamline compliance and governance controls
 * Implement strong multi-factor authentication (MFA) standards, passwordless solutions, and contextual access policies, * Establish SaaS Security Posture Management (SSPM) and conduct security posture reviews for corporate SaaS applications (Google Workspace, Slack, GitHub, Jira, Salesforce)
 * Define and enforce baseline security configurations, patch management policies, and MDM/EDR security controls across corporate endpoints (macOS, Windows, Linux)
 * Partner with IT Infrastructure and Operations teams to architect Zero Trust Network Access (ZTNA), VPN/SASE solutions, and secure remote worker access frameworks, * Develop custom security automation tools and scripts in Python or Go to eliminate manual IT/Enterprise security toil
 * Pioneer AI-powered enterprise security workflows leveraging Lambda's hosted LLMs to automate third-party risk analysis, access request approvals, and anomaly detection in corporate logs
 * Assess third-party vendor risks and build automated tooling to evaluate SaaS vendor security postures

Governance & Cross-Functional Alignment:

 * Collaborate with IT, Legal, HR, and Compliance teams to ensure corporate systems align with frameworks such as SOC 2, ISO 27001, and HIPAA
 * Establish internal security documentation, end-user security awareness guidelines, and self-service security options for employees
 * Define strategic roadmap initiatives for corporate security, driving measurable security posture improvements across all business units
