About the Role  

As a Senior Backend Engineer focusing on distributed systems at Mux, you will build and manage scalable and highly available applications and services that can reliably support the feature development and growing traffic of our products. Both of our existing products: Mux Data and Mux Video, ingest and process a high volume of data with strong latency and availability requirements. You will work on ensuring our platform is resilient, and will also be writing new application code to support product features. We’re looking for engineers that love both systems and application-level challenges across various teams, who will take on strong ownership of critical product infrastructure and enjoy being part of an inclusive and creative Engineering team.

Teams with Distributed Systems Roles at Mux:

Mux Video (Various Teams): Mux Video is an API platform that enables developers to build powerful on-demand and live video experiences at scale. We have several teams with backend roles under this product umbrella: Video Core Product (focused on integrating features that make our API more powerful) and Video Platform (focused on scalable ingest and delivery).

Mux Data: Mux Data is an observability tooling for developers working with video that monitors and aggregates insights for the end-to-end video playback experience. This team builds out the features as well as platform that support this product, e.g. our client-side SDKs, data dashboards, and the backend processing, aggregation, and compute platform.

  • Operate, tune, and continuously scale the platform that support growing traffic on these core products
  • Technologies you may touch include:
    • Code:  Golang, gRPC, Edge Compute
    • Cloud:  Google Cloud Platform, Amazon Web Services, Fastly, Cloudflare
