Mux is building the future of online video infrastructure. Our founders have previously built some of the biggest things in video technology (like Zencoder, Video.js, and Demuxed), and we're now building API-driven infrastructure to support the biggest use of the internet today: online video.

We have two products for developers.

  1. Mux Video is a simple API to instant video streaming, optimized by data and machine learning. Think Stripe for Video or the back-end of Netflix as a service.

  2. Mux Data is a real-time analytics tool for video streaming. Mux Data is trusted by developers at companies like Vimeo, CBS, and Wistia, and monitors billions of video sessions every month.

Why join us?
  • We have an amazing team and a great culture.

    The Mux team is behind three of the biggest brands in video technology: Zencoder (acquired by Brightcove), Demuxed (the conference for video engineers), and Video.js (largest open source video player on the web). The team today is composed of engineers from places like Youtube, Google, and Twitch. Working with a great team at an early startup means you can own a meaningful scope of work, while working closely alongside very strong engineers.

    We're backed by top-tier investors including Accel and Y Combinator.

  • We're growing quickly and the opportunity is huge.

    We grew revenue by 3x last year and will 5x this year. Video is literally a majority of the internet, and the #3 thing humans do with their time (after sleeping and working). It's amazing that video infrastructure is still basically an unsolved problem, and whoever solves this problem is going to do something big.

  • Our tech stack is well-designed.

    We run a modern microservice architecture deployed on Kubernetes. Our back-end is built on Golang and GRPC, heavily using event-driven architectures (Kafka). We run multi-region and multi-cloud (AWS and GCP) for reliability, performance, and cost. Our front-end is a well-designed React/Redux application calling an API layer built in Elixir. We unit test and code review everything and ship via CI/CD pipelines.


Engineering at Mux
Engineering team and processes

Engineering, design, and product management work together to understand customer needs and to solve problems. Teams are somewhat self-organizing but generally follow sprint or kanban processes, with weekly sprint planning meetings and daily standups. We invest in design and architecture up front, and code review and testing along the way. Because we're building technical products for developers, the company is driven more by product and engineering than by sales, which means we're able to build high-quality software that developers love.

Technical Challenges
  • Super Bowl scale (literally). Our real-time analytics platform tracks billions of video plays each month, and scales up to tracking millions of concurrent viewers.

  • Just-in-time video transcoding. Unlike everyone else in the world, Mux Video doesn't pre-transcode video before publishing - we transcode just-in-time when the first user watches video. This gives us huge advantages, but introduces interesting technical challenges.

Projects you might work on
  • Build services to deliver real time metrics about millions of concurrent viewers from billions of data points per month.

  • Orchestrate deployments for resiliency and cost effectiveness across a multiple-cloud multiple-region environment.
