Senior Software Engineer About Rivet Rivet is infrastructure for AI agents. The primitive is the actor: a durable, stateful process for every agent, session, and user, living in a standard Node.js or Bun backend. Everything else builds on it: agentOS (a computer for every agent, with filesystem, networking, bash, Python, and Node), Workflows (durable automation that sleeps, retries, and survives restarts), and Dynamic Apps (deploy the backends agents generate, 22 MB per app, scaling to zero and to millions). A library in development, a platform in production: Rivet Cloud, self-hosted (Apache 2.0), or fully air-gapped in your VPC. Code at github.com/rivet-dev/rivet.
