About the role 

As a Senior Site Reliability Engineer at Fable, you will play a critical role in ensuring the reliability, scalability, and efficiency of our platform as we continue to grow. 

Fable’s products support organizations in building more accessible digital experiences, and the reliability of our infrastructure is essential to delivering that impact.

Our values 

To lead, listen first 
You amplify voices that are less often heard and create space for those voices to grow. The quality of an idea doesn't correlate with the loudness of someone's voice. 

The brain is a muscle 
If you're going to do something, you will do it well. Practice often and rest when needed. Give your mind what it needs to thrive. 

Unlearn to learn 
What did we learn growing up, and what do we need to unlearn? It's essential to understanding our personal bias and position so that we can grow. 

What’s in it for you? 
At Fable, you’ll join a collaborative and mission-driven environment where you’ll work with people who care deeply about building a more inclusive digital world. We offer benefits such as stock options, career growth opportunities, professional development support, health and dental coverage, and more.
