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!

About the Role

As a Staff Software Engineer on the Platform Engineering Team at Mux, you will lead the design, evolution, and long-term strategy of the infrastructure that powers Mux’s high-traffic, distributed platform. You will operate as a technical leader across teams, shaping architecture, influencing engineering direction, and driving platform investments that enable the company to scale.

Our Platform Engineering team works cross-functionally to ensure that services are scalable, reliable, and easy to operate. At the Staff level, you will go beyond contributing to systems to define how those systems evolve over time. You will partner deeply with product and engineering leadership to identify opportunities, remove systemic friction, and build shared abstractions that improve the velocity and effectiveness of the entire organization.

We’re looking for an engineer who thrives in ambiguity, has a strong track record of building and evolving large-scale infrastructure, and is motivated by solving complex, cross-cutting problems. If you are passionate about Kubernetes, platform design, and raising the bar for engineering across teams, you should keep reading!
