Software Engineer, Ori

About this role

ABOUT OPENROUTER

OpenRouter is the leading 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 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 a Software Engineer on our Ori, to build out our family of products for putting any model to work in your terminal, in Slack, and on your desktop. Ori is built to answer the question from large buyer ICP, we are building the client side products for massive enterprise adoption of OpenRouter beyond the engineering organization.

Ori is small team built the current product in a few months. You'll work with that team, which is led by one of our co-founders, alongside product, design and the platform teams Ori is built on. This is a hands-on IC role with broad surface area and little process between you and shipping.

WHAT YOU'LL DO

• Build and ship across every Ori surface: the ori CLI and its harness integrations.

• Make model fungibility real in any harness. That means model switching, provider fallbacks, tool and prompt settings tuned to each model, and respecting org guardrails, all without extra auth for the user.

• Build the agent runtime underneath. That includes sandboxed agents that never see their own credentials, secrets management, session management and compaction, and skills that agents can learn, share and inherit across models.

• Take agents from a laptop to the cloud: deploy, fork and shut down agents on command, with agent state that is version-controlled and auditable.
