Senior Software Engineer, Proactive Security - Platform

About the Team

At DoorDash we're building the industry's most scalable and reliable delivery network to support our three-sided marketplace of consumers, merchants, and Dashers. Security Engineering is paramount to the success of our business, and DoorDash Security aspires to be one of the world's most admired Security Engineering teams. We are committed to building the world's most trusted on-demand logistics engine for delivery! We're expanding our team of great minds to help us secure and maintain a 24x7, no downtime, global infrastructure system that powers DoorDash's multi-sided marketplace of consumers, merchants, and Dashers.

About the Role

Our Proactive Security Engineering team is looking for a Senior Software Engineer, Proactive Security - Platform to build the paved paths that engineers across DoorDash, Wolt and Deliveroo use to access infrastructure, manage secrets and authenticate services.

You will be part of our inclusive, collaborative global Security Engineering Platform team responsible for building and operating tier-0 security services for access management, secret storage and identity, including our in-house Access Platform, Teleport and HashiCorp Vault. Your job is to make the secure path the easiest path: self-service, well documented, and built into the tooling engineers already use every day.

This is a US remote position reporting directly to the Manager of our Proactive Security Engineering Platform team.

You're excited about this opportunity because you will…

• Design, build and operate paved paths for privileged access, secrets management and identity on top of our access management and secret storage platforms.

• Build self-service tooling, SDKs, Terraform modules and integrations that let engineering teams adopt just-in-time access, short-lived credentials and dynamic secrets without filing a ticket.

• Design and operate highly available distributed systems, including replication, consistency and consensus, that underpin tier-0 services.

• Drive migrations off long-lived credentials and standing access. Success is measured in classes of exposure eliminated at the platform layer, not in shipping code for its own sake.

• Partner with Core Infrastructure, Compute, Data and product engineering teams to integrate paved paths into Kubernetes, CI/CD, and AWS and GCP environments across DoorDash, Wolt and Deliveroo.

• Participate in a follow-the-sun on-call rotation for tier-0 security services and raise the bar on Operational Excellence through monitoring, runbooks, incident response and root cause analysis.

• Help enable the secure adoption of AI tooling and agentic workflows through access control and secrets brokering for agents.

We're excited about you because…

• 6+ years of experience as a Software, Infrastructure or Security Platform Engineer at an internet scale organization.

• Bachelor's degree in Computer Science, Security Engineering, a related field or equivalent work experience.

• Strong software engineering skills in Go (or Kotlin, Java, Python), building production services and developer tooling.

• Hands-on experience building or operating access management and secret storage systems, such as PAM, secrets management or key management platforms. Experience with Teleport or HashiCorp Vault is a plus.

• Solid understanding of distributed systems, including replication, consistency and distributed consensus (e.g. Raft, Paxos).

• Working knowledge of identity and authentication standards such as OIDC, SAML, mTLS and workload identity (e.g. SPIFFE, AWS IAM Roles, GCP Workload Identity).

• Experience with Kubernetes, Terraform or other infrastructure as code, and AWS and/or GCP IAM.

• Track record of building internal platforms or paved paths that other engineers chose to adopt, with a strong focus on developer experience.

• Experience running highly available, no-downtime services with mature on-call practices.

• Clear verbal and written communication skills, and the ability to drive adoption across engineering teams.
