About the Position

Twitch is looking for a focused Application Security Engineer with a desire to play on the Blue Team. Maybe you’re a pen-tester who is bored of always winning; maybe you’re the local security advocate within your development organization. However you got to where you are, we want one thing from you – help make Twitch’s products as safe as they can be for our partners and viewers.

You’ll apply a holistic security perspective and escort Twitch’s products and features from ideation to deployment. Reporting to our Application Security Manager, you will provide consulting to product teams looking to try new things safely. You will review essential passages of code for safe practices. Most importantly, you will help build the tools that do the above for you as a force multiplier. And yes, where warranted, there’s some pen-testing in it for you as well, if you’re into that.

Please consider the responsibilities detailed below to be a mix of expectations and opportunities. We don’t expect everyone to already be great at everything. Everything sounds great except for one or two things? Please ask about them. Want to support our team without being on it? Please consider other security roles at Twitch.
