About OpenRouter OpenRouter is the open AI routing and infrastructure layer that enterprises use to access, manage, and optimize the best large language models across providers—without lock-in, capacity constraints, or unnecessary cost. We power some of the most advanced AI teams in the world by giving them the flexibility to move fast, scale confidently, and stay future-proof as models evolve.
As enterprise adoption of AI accelerates, OpenRouter sits at the center of how organizations operationalize LLMs across research, product, and production workloads.
About The Role We're hiring our first Security Engineer to own the safety of our systems, infrastructure, applications, and data. You'll build out the security engineering function from the ground up — implementing programs, build automated tooling, shipping fixes, and driving remediation across the stack that powers millions of API requests daily. This is a hands-on engineering role, not a paperwork role: compliance and IT are owned separately so you can focus on security work. You'll partner with engineering and senior leadership, set the bar for how we secure an AI gateway at this scale, and influence how we protect our customers and their data.
