Mux (YC W16) | SF, London, REMOTE | Full-Time | Elixir, Golang, TypeScript/React | https://mux.com/jobs

Mux is how developers build online video.

With Mux Video, developers gain access to a powerful API for video streaming--think Stripe for Video. You don't have to have strong feelings about ffmpeg settings, you just go. And with Mux Data, developers realize incredible insights into how their videos perform from platform to platform, place to place, and user to user.

I'm Ed, and I'm an engineer on the DevEx team here - you might have seen me around HN here and there. ;) This is, and I have to stress that I'm not kidding because everybody says this sort of thing, for real my favorite job that I've ever had. The team here is mind-blowingly smart, there is a real and concerted focus on not just competence but on the human side of things; one of the company's core values is "be human" and I thought it was marketing stuff 'til I joined and learned to my surprise that it is emphatically not. Also? Legit, the best onboarding experience I've ever had. During a pandemic, no less.

The tech stack actually manages to balance cool with useful, too. It's a multi-cloud environment running Kubernetes on AWS and GCP, with Elixir, Golang, and some NodeJS (some JS, mostly TypeScript), plus React and TypeScript for all the usual bells and whistles.

Mux is a good place to be and if video is your bag, or even just sounds interesting, you should check us out. Feel free to email me personally at Email is hidden with any questions you've got or head on over to https://mux.com/jobs and check out our openings. Even if you don't see an immediate spot that clicks with you, feel free to reach out anyway; we have a certain facility for finding room for amazing people.
