At Lyft, our mission is to improve people’s lives with the world’s best transportation. To do this, we start with our own community by creating an open, inclusive, and diverse organization.

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

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

We’re looking for the right person to join our Application Security team to support and mature our Bug Bounty program. We work closely with many teams across the company to review designs and educate on best practices. In order to be scalable, we need to understand root causes, identify similar issues across Lyft and drive sustainable remediation efforts.

Responsibilities:
  • Triage and validate issues identified through our Bug Bounty program
  • Collaborate with teams across Lyft to understand, verify and remediate identified security issues 
  • Proactively research new attack vectors that may affect Lyft.
  • Proactively identify further instances of the same issue through scripting and automation and drive resolutions for the underlying issues.
  • Test fixes to ensure we are getting the most value from our reports
  • Use your knowledge of frequent issues to create and provide guidance and best practices for Lyft engineers
  • Threat model and code review of features/services.
Experience:

Security superstars come from many backgrounds. We encourage you to apply even if you do not match this list perfectly.

  • Penetration testing against cloud environments and/or mobile (iOS/Android)
  • Development skills to automate code security assessment and scale your impact
  • Computer networking concepts and protocols, application and network security methodologies
  • Network security architecture concepts including topology, protocols, components, and principles (e.g., application of defense-in-depth)
  • Present findings, recommendations and results to leadership
  • Experience giving security conference talks.
  • Ability to communicate complex information, concepts, or ideas in a confident and well-organized manner through verbal, written, and/or visual means
  • Bug bounty research.
  • CTF experience.
  • Experience with (or a deep interest in) computer security, ideally in both attacking and defending services
  • When facing a problem that's poorly defined or outside of your expertise, you can quickly and independently 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
