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 Software Engineers with a passion in Security to help us scale. Come be part of the Security team at Lyft focused on enabling & empowering engineering teams to deliver secure services 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, consults 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.

We're looking for an engineer who's excited about growing & improving security at Lyft by building systems & promoting security throughout the company. You'll play a part in shaping the future of security at Lyft, & your work will have significant impact & visibility.


  • Architect & build services that improve the security of our systems with an eye towards scalability & avoiding unnecessary friction.
  • Evangelize our shared security responsibility model by collaborating with other Infrastructure teams at Lyft to ensure that our services & workflows are secure by default.
  • Work on embedding security best practices such as least privilege, isolation, monitoring, authentication & authorization across our infrastructure
  • Develop critical services that Lyft depends on such as our credential management service that provides secrets to all our services at Lyft.
  • Provide rich data to engineers at Lyft to drive manual & automated decision making by working on our open-source service Cartography, which shows relationships between our infrastructure assets.
  • Ensuring least privilege is enforced by improving role-based access control & Identity Access Management for our users & services.


  • Solid experience with a high level programming language (bonus points for experience with Python, Go-lang & shell scripts)
  • Experience with (or a deep interest in) computer security
  • When facing a problem that's poorly defined or outside of your expertise, you can quickly learn what you need to dig in, make sense of the problem, & start working towards a solution
