This description is a summary of our understanding of the job description. Click on 'Apply' button to find out more. Role Description We own ngrok’s core gateway layer — the infrastructure that sits between the internet and everything our customers run. Every request, response, retry, and timeout passes through here. Our job is to make sure that traffic is: - Routed exactly where it’s supposed to go - Secured correctly, every time - Allowed or blocked for reasons we can explain - Rate-limited and shaped without surprises - Observable when something inevitably goes sideways What You’ll Actually Do: - Build and operate the gateway core: You’ll work on the services every ngrok request passes through. They’re very fast, very hot, and have extremely high standards. - Design routing and security primitives everyone depends on: You’ll build low-level policy, routing, and validation systems used across the platform—making sure bad configs fail fast and don’t accidentally DDoS the internet. - Debug distributed systems in the wild: You’ll chase bugs caused by timing, load, and incorrect assumptions. Expect metrics, traces, packet captures, and the occasional “how is this even possible?” - Ship infrastructure people sleep on (in a good way): You’ll build simple, durable systems and clean abstractions that other teams rely on daily—while thinking about blast radius, safety, and rollbacks more than flashy demos. Qualifications - You’re comfortable in Go, Rust, C/C++, or Java (bonus points for Go) - You’ve built networking, proxy, or infrastructure systems in production - You understand TLS/mTLS - You enjoy systems that are invisible until they’re not - You’re passionate about building primitives other teams depend on - You’ve said “this needs to be rock solid” and meant it literally - Extra credit if you’ve worked on: - Gateways, proxies, or edge platforms - Security-critical infrastructure - Multi-tenant networking systems - Config-heavy systems that must never surprise users - Anything described as “simple” in the original proposal Requirements - ngrok runs entirely on AWS. - Engineers develop by SSH’ing into 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. - React is used for user interfaces, and GitHub supports our development workflows and remembers everything. Benefits - Full premiums covered on base healthcare, dental, and vision for you. Half covered for your dependents. Mental health and well-being support included. - 401(k) with 100% match up to 3% of your salary and 50% match up to another 2%. - Open, flexible vacation policy. - Up to 16 weeks parental leave for birth, up to 8 weeks for new parents (birth, adoption, fostering). - Annual professional development budget for books, courses, conferences, or whatever helps you level up. - Co-working space stipend if you want to get out of your house but aren't near our SF office. - 2x+ free lunches per week for employees onsite at our San Francisco office. - Company offsites twice a year. - Bi-annual reviews to ensure real feedback and competitive compensation.
