Software Engineer III / Senior, AI Gateway

Software Engineer III / Senior, AI Gateway About ngrok Inc. 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.

The Opportunity As a Software Engineer on the AI Gateway Team, you'll be shaping the foundation of how developers and enterprises securely connect their applications through ngrok. This role gives you the chance to design and implement distributed systems that enforce policies, manage trust, and deliver advanced endpoint capabilities—all at global scale.

You'll work on challenges that demand both technical depth and creativity : building high-performance distributed systems that route traffic with millisecond precision, securing sensitive workloads, and enabling the next generation of AI-driven applications. Every line of code you ship will directly influence how developers build, secure, and scale their most critical services on ngrok.

This is a remote position for candidates outside of the Bay Area and a hybrid role for candidates within commuting distance to San Francisco. Our Bay Area employees commute to the office on Tuesdays and Wednesdays. At this time, ngrok is unable to provide visa sponsorship for this position. Applicants must be authorized to work in the United States on a permanent, ongoing basis without the need for current or future sponsorship.

What You'll Do Build and evolve the gateway services that handle traffic routing, policy enforcement.

Implement new traffic policy objects (e.g., secrets, IP rules, mTLS / CA policies) to give customers fine-grained control over their applications.

Extend and optimize endpoint services that provide reliability and observability for developers.

Partner with product, platform, and security teams to ensure traffic management is robust, scalable, and enterprise-ready.

Write clean, high-quality, well-tested code and participate in thoughtful design / code reviews.

Investigate and resolve production issues across distributed systems.

Continuously improve the developer experience—simplifying how teams configure, secure, and scale their traffic.

Contribute to the evolution of shared infrastructure, tools, and libraries across ngrok.

You Are a Good Fit If You… Have 3+ years of experience writing high-quality production software in Go or languages like Rust, C, Java, or C++.

Understand networking and distributed systems fundamentals (protocols, TLS / mTLS, proxies, load balancers, traffic shaping).

Have experience building AI gateways, reverse proxies, API gateways, or working with AI / ML service traffic.

Are motivated by building scalable, performant systems that developers love to use.

Enjoy working at the intersection of infrastructure, security, and developer tooling / experience.

Value pragmatism—delivering solutions that balance complexity with simplicity and maintainability.
