Senior Software Engineer, Security Foundations; Networking Infrastructure Projects

At Lyft, our purpose is to serve and connect. We aim to achieve this by cultivating a work environment where all team members belong and have the opportunity to thrive.

Lyft's engineering team is growing rapidly, and we are looking for Software Engineers with a passion in Security to help us scale.

The security team designs and builds Lyft's security architecture, consults with other teams as they build and launch new products and features, proactively plans for the unexpected, and responds to incidents that occur. 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  to learn more about some of the things we've built.

We're looking for an engineer with a strong networking background who's excited about growing and securing distributed systems throughout the company. You'll play a part in shaping how service networking works at Lyft, with significant impact and visibility.

• Work on our network security initiative such as our Internet edge proxies (Envoy), Web Application Firewall, service-to-service authentication and authorization.
• Architect and build services that improve the security of our systems with an eye towards scalability and avoiding unnecessary friction.
• Evangelize our shared security responsibility model by collaborating with other Infrastructure teams at Lyft to ensure that our services and workflows are secure by default.
• Work on embedding security best practices such as least privilege, isolation, monitoring, authentication and authorization across our entire infrastructure (systems, application, networking).
• Develop critical services that Lyft depends on such as our credential management service that provides secrets to all our services at Lyft.

• Solid experience with a high level programming language (bonus points for experience with Python, Go-lang and shell scripts)
• Strong understanding of networking concepts (TCP/IP, HTTP, TLS, DNS) and working experience with edge or sidecar proxies.
• Identity and Access Management (IAM): provisioning least privilege access to users and services. Familiarity with authn/authz and frameworks and concepts related to SSO, SAML, OAuth, OpenID.
• Experience with Amazon Web Services (AWS) or another major cloud service provider
• Kubernetes and container security and running fleets of endpoints or servers in the cloud.
• Cryptography, PKI, or key/certificate distribution
• Running multi-tier or distributed web services at scale

• When facing a problem that is 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.

• Great medical, dental, and vision insurance options with additional programs available when enrolled.
• Mental health benefits.
• Family building benefits.
• Child care and pet benefits.
