Backend Senior Software Engineer, Identity

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. 
Our Senior Software Engineers lead and mentor engineers, delivering high-value products for our customers and infrastructure that enables our business to scale.
Vanta’s product monitors the security posture for thousands of companies, pulling tens of millions of API calls of data per day, pushing information from hundreds of thousands of laptop agents, and running tests against that data continuously to identify potential security threats. Our infrastructure and tooling need to stay ahead of exponential growth in our customer base. As a Senior Software Engineer at Vanta, you’ll be responsible for setting technical direction to provide a strong foundation for our infrastructure to scale with our business. You will also drive complex projects across our technical stack and mentor our talented engineering team. Your past experience will be leveraged to enable and accelerate Vanta’s growth.
