Software Engineer, Security

At Lyft, community is what we are and it’s what we do. It’s what makes us different. To create the best ride for all, we start in our own community by creating an open, inclusive, and diverse organization where all team members are recognized for what they bring.

Our drivers and passengers entrust Lyft with their personal information and travel details to get where they're going, and expect us to keep that data safe. Lyft's security team leads efforts across the company to ensure our systems are secure and worthy of our users' trust. The security team designs and builds out Lyft's security architecture, consults with other teams as they build and launch new products and features, and responds to incidents that occur. We're software engineers first, we believe in scaling security through engineering and automation, and we ship frequently. Our work spans the entire company and takes place at all levels of the stack, from infrastructure to web application security, as well as mobile apps and IT.

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


  • Build tools and services that improve the security of our systems with an eye towards scalability and avoiding unnecessary friction

  • Evangelize our shared security responsibility model by working with other teams to ensure that all critical systems and workflows are secure by default

  • Work on embedding security best practices such as least privilege, isolation, monitoring, authentication and authorization across our infrastructure

  • Develop runbooks for IT and security teams to handle incidents and help scale incident response activities within the team and across the company

  • Investigate and handle alerts, reports of unusual behavior, and security incidents

  • Provide security guidance on a constant stream of features and products

Experience & Skills:

  • Solid experience with a high level programming language (bonus points for experience with Python and shell scripts)

  • Experience with (or a deep interest in) computer security, ideally in both attacking and defending web applications

  • 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, and start working towards a solution

  • You're a great communicator, and can advocate for your proposals while also empathizing with your teammates' goals and priorities

  • You understand that security work must be prioritized because all teams have finite resources. You have good judgment and a sense of when to compromise and when to hold your ground

  • Experience with Amazon Web Services (AWS) or any other major cloud service provider

  • Running multi-tier or distributed web applications at scale

  • Computer network security or major computer networking protocols (e.g. TCP/IP, HTTP, TLS, DNS)

  • OS and container security and running fleets of endpoints or servers in the cloud

  • Reverse engineering, malware analysis, or digital forensics

  • Data classification or data privacy protection

  • Cryptography, PKI, or key distribution
