Security Engineer, Corporate Security

Flexport is a technology company making global trade easier. The Security Engineer, Corporate Security role involves advancing identity posture, endpoint and device lifecycle management, SaaS posture, and automation to protect the company's infrastructure and users.

• 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.

• 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.

• We're in the San Francisco office regularly to work through incidents and detection design in person.
• We stay closely aligned with teammates on other continents via Slack, video, and async docs.
• We have the latest hardware and software, including frontier AI models on day one.
• We're agile, but not dogmatic. Teams decide how they work best.
• Broad, real ownership: at this level elsewhere you might own a slice of a control; here you'll own well-defined projects end to end, from design through rollout, with support scoping the ambiguous parts.
• Every device policy or identity control you ship protects every Flexporter, immediately — no six-month rollout to a subset of customers.
• You're part of PSI: security is treated as infrastructure to build, not policy to enforce, and platform and infrastructure engineers are a Slack message away.
• Base salary is just one part of our total rewards package at Flexport, which also includes bonus, equity, and comprehensive benefit offerings such as medical, dental, and flexible time off.
