You are a full-stack engineer who wants to work everywhere, not just a small subset of components. Experience / interest in working in a variety of layers and technologies within a SOA is a must for our team. This includes: client-side React & Redux, MVC-based web architecture, external RESTful APIs, distributed (and in our case, highly scaled) request handling services, no-SQL and relational SQL databases, many-layered data pipeline (e.g. data bus architecture, Hadoop / MPP data warehouse, etc.) that moves hundreds of thousands of items per second, and data visualization (e.g. Tableau). Experience in all these layers is not strictly required, but we do like to see experience working in more than one, as well as eagerness to work on projects that might slice through them all.

You have product-driven software development experience using a modern, object-oriented language. Memory-managed languages are best -- .e.g. C#, Java, Python, Ruby, etc. We do most of our work in C#/.Net, but specific experience here is not required.

Cool stuff about TTD:

Mux | All sorts of roles across the organization | SF, London | Full-time | https://mux.com/jobs

Just going to drop in the blurb on our jobs page, but the tl;dr is we build cool video infrastructure. Our stack is mostly Elixir, TypeScript (React/Redux), Go.

The first product we launched was analytics and performance monitoring - think “NewRelic for Video” - used by major video streaming companies like PBS, Vimeo, CBS Interactive, and the New York Times to monitor and improve billions of streams.

In early 2018, we launched Mux Video, a simple API to video hosting, encoding and streaming - think "Stripe for Video" - which uses our performance data, machine learning, and just-in-time encoding for unmatched video quality and efficiency. POST a video in; GET a video out that plays anywhere and is deeply optimized for the target device and user. We think building with video should be fun, not complicated.

You’ll be joining an amazing team from places like Google/YouTube, Twitch and Brightcove. Our founders previously started (and sold) Zencoder, an early leader in cloud video technology. We also authored Video.js, the biggest HTML5 video player on the web.

If you want to chat more about any of these roles or the company before applying, feel free to drop me a line: matt at mux.com
