About Ngrok

ngrok is developer infrastructure that routes and secures traffic to your apps, APIs, and AI models, wherever they run. Start on localhost, ship to prod. Backed by Lightspeed.

About the role

ngrok runs entirely on AWS. Engineers develop by using remote development tools and/or ssh to connect to remote EC2 environments that run a full Kubernetes cluster of the ngrok stack, closely mirroring production. The codebase is primarily Go and TypeScript. We use Postgres for persistence, Kafka for streaming, Protobuf for service boundaries, and Kubernetes, Terraform, Helm, and Buildkite to operate and ship reliably.

What they're looking for

  • You’re comfortable in a statically typed, compiled language such as Go, Rust, C++, or Java (with bonus points for Go)
  • Experience in frontend engineering, including expertise in TypeScript, React, HTML, CSS
  • You’ve worked with AI/LLMs and can appreciate their unique brand of edge-cases
  • You care about developer experience and thoughtful abstractions
  • You enjoy defining system behavior, not just plumbing
  • You’ve thought about retries, limits, and costs before being asked
More about this role

ngrok is an all-in-one cloud networking platform that secures, transforms, and routes traffic to services running anywhere. Instead of cobbling together nginx, NLBs, VPNs, model routers, and oodles of other tools, developers solve every networking problem with one gateway. Doesn’t matter if they’re sharing localhost or running AI workloads in production.

We're trusted by more than 9 million developers at companies like GitHub, Okta, HashiCorp, and Twilio. What started as a way to put your local app on a public URL has grown into a universal gateway for API delivery, AI inference, device fleets, and site-to-site connectivity. It’s the same ngrok that millions of developers have loved and leaned on every day for years, now with the power to run production traffic at scale.

  • We are obsessed with our pets, Viper sunglasses and Bufo (yes, the toad)
  • We have a designated Chief Emoji Officer - they are vital to our success!
  • We like software that’s serious and culture that’s not
