Full job description
Senior Software Engineer About Rivet Rivet is composable, open-source infrastructure for modern AI requirements. Everything we do is built with an emphasis on self-hosting, flexibility, and performance. We believe no good engineering happens in a vacuum, so we work closely with customers to make sure Rivet fits their use case and is flexible enough for their roadmap. At the core of Rivet is Actors: a primitive for stateful workloads. It provides addressable, long-running processes, SQLite-per-actor, WebSockets, and hibernation. Actors provide a powerful foundation for use cases like agentOS (virtual operating system for agents), Workflows (durable execution engine), and Dynamic Apps (AI-generated app hosting). Rivet Cloud provides a managed way to run the Rivet stack. Most of Rivet is open-source (Apache 2.0), self-hostable, and can be fully air-gapped in your VPC. Code is available at github.com/rivet-dev What You’ll Work On
