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.

The Networking team is responsible for all edge & service-to-service network traffic dedicated to making the best ride possible, from our mobile app to our internal microservice architecture. This means providing the most reliable network seamlessly so that our engineers can build platforms that scale. This also means providing tooling to either make the network easy to understand or abstract the network completely.

As an infrastructure engineer in the Networking team, you will build creative engineering solutions to operational problems. You will help operate one of the largest Envoy-based service meshes in the industry, which gives you & the team the opportunity to regularly talk about our work in the community & at conferences, including EnvoyCon, KubeCon, Google Next & re:Invent. Our team regularly gives back to the service mesh community by developing new components & providing patches to the upstream Envoy project.


  • Build & deploy open-source Envoy with Lyft private extensions to the entire fleet, & create systems to make that process faster, iterative, & reliable
  • Investigate how network configurations are being tuned & figure out how to set it automatically or abstract it away (e.g., adaptive concurrency & admission control)
  • Proactively identify potential outages & build systems to triage & fix.
  • Further automate & reduce the operational burden on our Kubernetes-based service mesh
  • Contribute to designing & building configuration, testing & deployment automation frameworks
  • Drive incident responses to long-term conclusion via mentoring the team on operational best practices & potential long-term systemic fixes
  • Build & foster partnerships throughout the organization with a devotion to exceptional customer experience
  • Never settle for the status quo, deliver operational excellence for Networking, Service Mesh & Edge

  • Expert level knowledge of an enterprise cloud provider (AWS, GCP, Azure)
  • Hands-on experience implementing & maintaining configuration controls through infrastructure-as-code
  • Take pride in reducing technical debt; your attention to small details & keeping code/configuration clean & maintainable is something you value
  • Value root causing operational issues & implementing systemic solutions & automation to make sure they no longer happen
