Engineering Manager, Proactive Security - Platform

DoorDash is a technology and logistics company building a scalable delivery network for consumers, merchants, and Dashers. The Engineering Manager, Proactive Security will lead the technical direction for platform hardening across DoorDash, Wolt, and Deliveroo, manage security engineering teams, and oversee cloud infrastructure, access services, secrets management, and operational excellence.

Responsibilities:

• Set and execute the technical vision for the Security Engineering Platform team, spanning AWS and GCP account/workload hardening, and vital tier-0 services (Access, Identity, Teleport, HashiCorp Vault, Tokenization and others)
• Influence and drive improvements to engineering standards, leverage advancements and LLMs to improve productivity and velocity
• Own the hardening roadmap for tier-0 cloud infrastructure and access services, backed by rigorous, follow-the-sun on-call. Success is measured in eliminating classes of misconfiguration and exposure at the platform layer, not in shipping code for its own sake
• Coach and mentor highly skilled tech leads and engineers as a "player-coach," leaning in at the lowest technical level on cloud hardening, identity, and secrets management problems, and lead the team to build the right durable controls
• Partner cross-functionally with Core Infrastructure, Compute, Data, and other engineering platform teams to harden the shared cloud and access substrate that all of DoorDash, Wolt, and Deliveroo build on, and deliver bespoke, in-house services where vendored platform controls don't fit
• Build and maintain high Operational Excellence (OE) practices for tier-0 security platforms with rigorous on-call rotations, clear escalation paths, and minimal downtime, since these systems are load-bearing for every other team's ability to ship and operate safely
• Drive continuous hardening of AWS and GCP environments so insecure defaults are annihilated and prevented before they ever reach production
• Influence and enable the secure and responsible adoption of AI tooling and agentic workflows from a platform hardening and access-control perspective

Requirements:

• 12+ years of experience as a Security or Infrastructure Platform Engineer at an internet-scale organization, with 3+ years of demonstrated technical leadership leading teams building outcomes at global scale
• Deep hands-on expertise hardening AWS and/or GCP at scale, including account structure, guardrails, workload and network posture, and golden image pipelines
• Demonstrated technical leadership operating access and secrets infrastructure such as Teleport, HashiCorp Vault, or equivalent PAM/secrets-management platforms, including the on-call rigor required to run them as tier-0 services
• Track record of building and running highly available, no-downtime platform services with mature on-call practices, incident response, and root cause analysis
• Master's degree in Computer Science, Security Engineering, a related field, or equivalent work experience
• Demonstrated technical leadership designing scalable security platform controls and processes that meet required regulatory requirements
• Exceptional problem solving of complex, systemic infrastructure issues that require audacious thinking, rigor, and creativity
• Exceptional verbal and written communication skills - you will confidently shape and lead the Security Engineering Platform function globally and influence stakeholders across core infrastructure, product, and other engineering teams toward hardened, secure-by-default outcomes
