Senior Engineer, Core Client - Frontend Platform

Who we are:

MasterClass is transforming online education by enabling anyone in the world to learn from the very best. We are deconstructing what makes an actor able to cry on demand, how an athlete defies gravity, and what it takes to write a bestseller. Our online learning content is available to students anywhere anytime, which supports our mission to ignite the greatness in others.

We are a quickly growing VC-funded startup based in San Francisco, with additional offices in Los Angeles. We have created online classes taught by famous masters— Gordon Ramsay, Serena Williams, Neil deGrasse Tyson, Sara Blakely, David Sedaris, Bobbi Brown, Timbaland, Anna Wintour and many more to come.

Since launching in 2015, we have been growing our team. Apply now to find out more about what we are doing behind the scenes.

Who you are:

While you've enjoyed building out wonderful user features and writing elegant solutions in the past, you find yourself wanting to get deeper into building the tools and improving architecture to better support future growth of the codebase. You enjoy finding patterns to turn into abstractions that make sense, and build on sensible ideas to support other teams' goals. Equally, you’re interested in working with other engineering teams, teaching/mentoring, and collaborating on solutions for multi-team systems. Complexity is not the goal, sustainability is. The greatest feeling in the world is getting the code to move out of the way to make way for ideas and progress. You consider yourself an engineering leader, wanting to drive critical architecture decisions and implementation.
