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.

Lyft connects people to transportation to change the way we live & get around our communities. Lyfts engineering team is growing rapidly, & we are looking for Technical Program Managers to help us scale. Come be part of a new team at Lyft focused on enabling & empowering engineering teams to deliver at scale.

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, & 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 Detection Team will work within Security to assist Lyft in making automated & informed decisions. We work to provide meaningful & timely alerting of high risk activity across the Lyft estate in an automated, verifiable & measurable way. This involves engineering solutions to improve our capability & coverage, as well as working with teams across Lyft to improve our security posture.
