Senior Software Engineer, Agent

ngrok Inc. • San Francisco, CA

92d • $172,000 - $215,000

About The Position

At ngrok, we believe that doing networking the right way should also be the easy way. Over the last 10 years, we’ve given developers and engineers simple interfaces for getting traffic into their apps and APIs without forcing them to deal with legacy proxies, external load balancers, or VPNs, and we’re now part of the standard stack for more than 9 million developers at some of the world’s top technology brands, like GitHub, Okta, HashiCorp, and Twilio. Over the last few years, we’ve completely changed how that interface looks and works to make it easier, more composable, and infinitely flexible. We now give anyone who needs a “front door” to their apps or APIs powerful tools to orchestrate traffic, secure public endpoints, accelerate their services on a global network, observe all traffic passing to/from their network, and much more. The ngrok that millions love and trust has been completely transformed for the better.
