About Mux

Mux is video for developers. Our mission is to democratize video by solving the hard problems developers face when building video: video encoding and streaming (Mux Video), video monitoring (Mux Data), and more. Video is a huge part of people’s lives, and we want to help make it better.

We’re committed to building a healthy team that welcomes diverse backgrounds and experiences. We want people who care about our mission, are ready to grow, believe in our values (from Be Human to Turn Customers Into Fans), and want to improve the people around them.

You’ll join a tight-knit team with experience at places like Google, YouTube, Twitch, Reddit, Zencoder, Fastly, and more. Our founders previously started (and sold) Zencoder, an early leader in cloud video technology, and authored Video.js, the biggest HTML5 video player on the web. We organize Demuxed, the premier conference for video engineers in the world. 

We’re backed by top investors like Coatue, Accel, Andreessen Horowitz, and Y Combinator. You’ll get to work with amazing companies: hundreds of startups, plus Strava, Patreon, Vimeo, Robinhood, PBS, and Equinox. Customers, large and small, love working with us and love our team.

We are building something big together. We’d love to hear from you!

As a Senior Video Software Engineer at Mux, you will help build and scale powerful API-based functionalities for our core product, Mux Video. Our video engineering teams evolve our video transcoding and processing pipeline to deliver powerful features that serve a wide range of customers. We have worked on challenging problems ranging from just-in-time transcoding to per-title encoding — and we are just getting started! We are looking for a Video Software Engineer with strong engineering fundamentals that wants to join a fast-paced, creative, and inclusive Engineering team.

What You'll Do

• Collaborate with your team on a technical roadmap and product goals

• Build the foundations for future media products and features

• Help to develop and evolve our transcoding platform to support new capabilities and video quality concerns

• Work on exciting aspects of encoding a wide variety of video at a large scale (millions of videos every month)

• Design, maintain, and build services and video processing tooling and workflows to enable new features that meet performance requirements

• Work with platform and video delivery teams to ensure our features continue to meet core reliability and performance SLIs as we grow and as our product evolves

Who You Are

• 5+ years of experience in production Backend & Video Engineering using Golang, C, C++, or other similar languages, with a successful track record of contributing to sizable projects from start to finish with end-user impact.

• You’re a strong engineer comfortable working across multiple platforms and environments.

• Solid engineering fundamentals (CS degree a plus). Strong knowledge of a general purpose programming language (we primarily use Golang, but our video encoding stack has a lot of C++ and C)

• Troubleshooting large scale, highly available distributed systems

• Designing and building applications with reliability and scale in mind: SRE principles, observability, high-availability

• Prior experience of working in a subset of these technologies (you don’t need to have all of them!):

  • Go, C, Modern C++

  • ffmpeg/libav and/or other open source media libraries

  • HTTP Streaming formats: HLS and DASH

  • Packaged media formats (e.g. fMP4, Transport Streams)

If you don't have all of these requirements but think your experience could be a great fit, that's okay! Please apply and we can talk about what's most needed in the role.
