[Remote] Security Engineer, Corporate Security

Note: The job is a remote job and is open to candidates in USA. Flexport is a technology company building solutions to make global commerce easier through innovative technology. The Security Engineer, Corporate Security will build and ship security automation across identity, endpoints, devices, and SaaS applications, including access controls, detection capabilities, device policies, and SSPM tooling. The role will also automate operational processes, document runbooks, and partner with IT and People teams to implement effective security controls.

Responsibilities

• Advance our identity posture: SSO coverage, phishing-resistant MFA rollout, SCIM lifecycle automation, and least-privilege access across the SaaS and cloud estate
• Build the detections and guardrails that catch account takeover, MFA fatigue attacks, and session token theft before they turn into incidents
• Write and ship device policy as code — configuration profiles, remediation scripts, and enforcement rules across macOS and Windows — with staged rollout and rollback built in from day one
• Maintain and improve our EDR stack's detection and response coverage across the fleet
• Reduce SaaS risk at scale through SSPM tooling and automation, including detection of risky OAuth grants, shadow IT, and configuration drift across our critical SaaS applications
• Own security configuration for the SaaS tools hundreds of Flexporters use daily (Google Workspace, Slack, and similar), and keep pace as we add AI agents and MCP integrations to that surface
• Automate the parts of corporate security that don't need a human — device provisioning, access reviews, vendor security questionnaires — so the team scales with headcount instead of straining against it
• Write runbooks and documentation that make the rest of the team more capable, and partner with IT and People teams to ship controls that don't create the friction that drives people to workarounds

Skills

• Typically 2–5 years of experience in corporate, enterprise, or IT security engineering — we care more about what you've shipped than the exact number
• Hands-on experience with modern endpoint management and EDR tooling (Jamf, Kandji, Intune, CrowdStrike, SentinelOne, or similar)
• Working knowledge of identity protocols (SAML, OIDC, SCIM) and a major identity provider (Okta, Entra, Google Workspace, or similar)
• Comfort writing real code or scripts (Python, Go, or similar) to replace manual, ticket-driven work with automation
• Clear, practical communicator who can explain a control tradeoff to an engineer, a salesperson, and a VP without changing the facts
• Experience with SSPM tooling and OAuth-grant governance
• Exposure to DLP or insider-risk tooling
• Familiarity with infrastructure-as-code (Terraform) for managing security configuration
• A point of view on how agentic AI tools and MCP integrations change what corporate security needs to watch for
• Interest in growing into a broader corporate security or detection engineering scope over time

Benefits

• Bonus
• Equity
• Comprehensive benefit offerings such as medical, dental, and flexible time off
• The latest hardware and software, including frontier AI models on day one
