At Lyft, our mission is to improve peoples lives with the worlds best transportation. To do this, we start with our own community by creating an open, inclusive, & diverse organization.

Our drivers & passengers entrust Lyft with their personal information & travel details to get where they're going & expect us to keep that data safe. Lyft's security team leads efforts across the company to ensure our systems are secure & worthy of our users' trust.

The security team designs & builds Lyft's security architecture, consult with other teams as they build & launch new products & features, proactively plans for the unexpected, & responds to incidents that occur. Our work affects the entire company & takes place at all levels of the stack, from infrastructure to web application security, as well as mobile apps, IT, bikes, scooters, & autonomous vehicles. We try to approach security from a software engineering standpoint. We believe in scaling security through automation & tooling & we ship frequently. Check out our blog posts at to learn more about some of the things weve built.

The Security teams mission: Empower the company to ship secure products. Provide clear guidance on secure code & implement quality gates across our software delivery pipeline.
