The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic’s complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI. What is The Role : Join the InfoSec - Security Architecture team as a Senior Information Security Infrastructure Engineer , where you'll have the chance to play a key role in protecting our organization's data and systems. This position offers the opportunity to work on meaningful projects that directly impact our security posture and collaborate with a skilled team passionate about information security. In more details: We ingest the security telemetry that the whole security org runs on. In this role you'll get that telemetry into Elasticsearch consistently and keep the underlying Elastic clusters healthy. You own the pipeline end to end: from a new security data source landing, through ingest pipelines, into the indices detection, IR, and consulting teams query, plus the clusters that store it all. What You Will Be Doing : Security telemetry ingestion - build and maintain ingestion of security-relevant data into Elasticsearch (cloud provider audit logs, identity/SaaS activity, endpoint and asset data). This means integrating with third-party and cloud provider APIs to pull telemetry: auth, pagination, rate limits, and handling schema changes. Both Elastic integrations and one-off custom integrations. Keep the Elastic Cloud on Kubernetes clusters healthy. Monitor and upgrade them regularly. This involves updating versions and build

About Flexport: At Flexport, we believe global trade can move the human race forward. That’s why it’s our mission to make global commerce so easy there will be more of it. We’re shaping the future of a $10T industry with solutions powered by innovative technology and exceptional people. Today, companies of all sizes—from emerging brands to Fortune 500s—use Flexport technology to move more than $19B of merchandise across 112 countries a year.

Ready to tackle global challenges that impact business, society, and the environment? Come join us. All security disciplines work under the umbrella of the combined PSI (Platform, Security & Infrastructure) team: we build the paved path and tooling that hundreds of engineers around the world rely on every day to ship. This is not a compliance or certification role. You won't be measured on audit portfolios. You'll be measured on the guardrails you build and whether engineering teams reach for them by default. A misconfigured IAM boundary here doesn't just degrade a dashboard: it can stall a customs filing or strand a container. Flexport also runs a genuinely heterogeneous estate: hundreds of services, carrier and customs integrations, and infrastructure spanning three continents, which makes multi-account architecture and cross-border data handling real problems rather than exam questions. What You'll Do Architecture & guardrails Design and review cloud security architecture for AWS and Kubernetes: account structure, network segmentation, workload identity, and secure-by-default patterns for new services. Fix the Terraform module, not the finding — drive remediation-at-source so misconfigurations get closed at the pattern level, not one ticket at a time.

Assess unfamiliar customer environments and lead technical implementation plans with the Compliance Lead. Configure and secure Microsoft 365, GCC High, Azure, Entra ID, Active Directory, Google Workspace, Google Cloud Identity, and hybrid environments. Design, migrate, and operate endpoint-management programs across multiple mobile device management and unified endpoint management platforms, including Jamf and Microsoft Intune. Implement identity, multifactor authentication, least privilege, endpoint security, logging, vulnerability management, patching, backup, and recovery controls. Configure and troubleshoot Windows, macOS, iOS, Android, networks, firewalls, VPNs, segmentation, DNS, and secure remote access. Work directly with customer IT teams, service providers, and vendors to resolve complex technical issues. Validate completed work and produce clear configuration records, diagrams, evidence, and runbooks. Guide other implementation engineers and turn repeatable work into standards, scripts, and automation. Minimum Experience and Qualifications: Senior-level experience designing, administering, securing, and troubleshooting varied business IT environments.
