Senior Security Data Engineer

At DoorDash, including international brands Deliveroo and Wolt, we’re building the industry’s most scalable and reliable delivery network to support our three-sided marketplace of consumers, merchants, and Dashers. Global Cyber Defense is a highly talented and globally distributed team that covers response, intelligence, insider risk, threat hunting, automation, and detection engineering. We exist to keep our brands safe for the Dashers, merchants, and consumers who depend on us. Our mission is to detect, investigate, and respond to cyber threats with speed and precision, while continuously hardening our defenses through automation, AI, and cross-regional collaboration.

Security at DoorDash, Deliveroo, and Wolt runs on telemetry, and our data pipelines team owns all of it. You will own multi-terabyte-per-day ingest across AWS and GCP, including reliability, cost, and schema, so that every detection engineer, threat hunter, and responder across three brands can find what they need. Most of your week goes to code, pipelines, and query performance rather than alert triage. The team spans the US and UK, so you will be in the room (or the thread) with IT, legal, privacy, incident response, insider risk, threat intelligence, and detection engineering on a regular basis. Very little of this work happens in isolation, and that is the fun of it. This role reports to the Senior Manager of Cyber Defense in the United States. The role includes participation in an on-call rotation for pipeline health.

You’re excited about this opportunity because you will…

• Own multi-terabyte-per-day log pipelines across AWS and GCP: ingest, routing, enrichment, schema management, and onboarding new sources as the business adds them

• Control ingest cost and volume, cutting noise at the edge without dropping the audit logs investigators depend on

• Model security data and tune query performance in Snowflake, BigQuery, and Redshift, including the tables detection engineering builds on

• Ship production services and integrations that other teams depend on: custom SIEM connectors, API clients, and automation

• Set and defend SLOs for log availability and freshness, and build the dashboards and alerting that prove them

• Own infrastructure as code and CI/CD for all of the above, including the deployment path that detections-as-code rides on

• Build AI agents and automated runbooks that speed up triage and time to fix across cloud infrastructure

• Enforce IAM and service account governance for the pipeline's cloud workloads

• Lead cross-functional projects spanning infrastructure, platform engineering, and incident response

• Create and maintain the standards and documentation that keep the service consistent, and mentor engineers across Cyber Defense

We’re excited about you because you have…

• 5+ years building and operating high-volume data pipelines in production at multi-terabyte-per-day scale, with tools like Kafka, Cribl, Dataflow, Kinesis, or CloudWatch

• 4+ years writing production software in Python, Go, Rust, or Java: services and tooling that other engineers run, beyond one-off scripts

• Deep hands-on experience with AWS and GCP, including infrastructure as code and ownership of CI/CD pipelines on GitHub, GitLab, or Bitbucket

• Strong SQL and data modeling in a columnar warehouse such as
