Job description

• 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
• 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 builds. Manage capacity and shards. Handle index lifecycle management (ILM). Enable cross-cluster search (CCS)
• Use Terraform to manage cloud infrastructure and Elasticsearch resources. This includes managing pipelines, index templates, and alerts. Utilize Kubernetes and Helm to deploy scheduled ingest jobs
• Use AI automation and tooling to reduce toil. This includes self-healing jobs and health checks. It also involves alerting, internal CLIs, and AI or agent-assisted workflows for investigation and operations
• Data quality & reliability - Own the “is the security data actually flowing correctly?” question. Monitor backfills. Ensure that schemas and fields are consistent. Keep an eye on costs

Benefits

• Toast to your health: Fully paid health coverage for you and your family, in many locations.
• Craft your calendar: Flexible location and schedule for most roles.
• Create space for you: Distributed by design workforce, plus generous number of vacation days each year.
• Embrace parenthood: Minimum of 16 weeks of parental leave, plus generous family formation benefits.
• Give back your time: 40 hours each year to use toward volunteering with organizations and causes you’re passionate about.
• Amplify your impact: Double your charitable giving - we match donations up to $1500 USD (or local currency equivalent).
