Senior Director of Strategic Finance

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 premiere 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

The Sr. Director of Strategic Finance will own the financial strategy and analysis that underpins key business decisions at Mux. You will develop a rigorous understanding of the drivers behind our operating model, manage business performance, and influence investment decisions. This role demands a hands-on leader ready to drive high-impact cross-functional projects—from pricing changes to marketing spend initiatives to M&A. You will own end-to-end financial planning processes, forecasts and financial models. You will also partner with functional leaders on strategic initiatives to help them achieve their operational goals. You will lead a team that includes business operations, accounting, and deal desk, and identify opportunities to improve efficiency across the team’s workflows using AI tools and best practices.
