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.

• 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

• 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 Snowflake, BigQuery, or Redshift, covering partitioning, cost control, and query tuning
• A track record owning reliability for a platform other engineers depend on, including on-call
• Experience building executive dashboards and engineering metrics that people actually act on
• Proven leadership and technical project management across infrastructure, platform engineering, and incident response
• Exceptional written and verbal communication, a collaborative instinct, and a habit of continuous learning
• Familiarity with an enterprise SIEM as an operator or a consumer (Google SecOps/Chronicle, Splunk, Elastic, CrowdStrike LogScale) is a plus, as is time with Kubernetes, Docker, and runtime security controls
• Any hands-on time with security telemetry sources, detections-as-code (YARA-L, Sigma, SPL), LLM-assisted workflows, penetration testing, red teaming, or triaging bug bounty reports is a bonus

At DoorDash, our mission to empower local economies shapes how our team members move quickly, learn, and reiterate in order to make impactful decisions that display empathy for our range of users—from Dashers to merchant partners to consumers. We are a technology and logistics company that started by enabling door-to-door delivery, and we are looking for team members who can help us go from a company that is known as the place you order food to a company that people turn to for any and all goods.

DoorDash is growing rapidly and changing constantly, which gives our team members the opportunity to share their unique perspectives, solve new challenges, and own their careers. We're committed to supporting employees’ happiness, healthiness, and overall well-being by providing comprehensive benefits and perks including premium healthcare, wellness expense reimbursement, paid parental leave and more.

We’re committed to growing and empowering a more inclusive community within our company, industry, and cities. That’s why we hire and cultivate diverse teams of people from all backgrounds, experiences, and perspectives. We believe that true innovation happens when everyone has room at the table and the tools, resources, and opportunity to excel.
