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](https://github.com/rivet-dev) ## **What You’ll Work On** * Rivet Engine (Rust, FoundationDB, Postgres, ClickHouse, NATS): the control plane that powers Rivet Actors * Actor orchestration (Pegboard) * SQLite & filesystem storage layer (Depot) * Durable execution & background jobs (Gasoline) * Traffic routing & edge network (Guard) * Multi-region Paxos KV (Epoxy) * Rivet SDK (Rust core + TypeScript bindings): the SDK used to work with Rivet Actors * agentOS (Rust core + TypeScript bindings): virtual operating system for agents with execution, filesystems, orchestration * Workflows & Dynamic Apps (TypeScript): thin SDKs built on top of Rivet Actors * Rivet Cloud: multi-tenant, edge routing, autoscaling, and observability Almost everything you write will be public. ### AI Policy We break down our codebase in Rivet: * Core engine: no/limited ai for mission critical + “off rails” code * SDKs + frontend: reviewed ai for routine + “on rails” code * Website: just test the output ### **Requirements** * 6+ years on backend or infrastructure systems * Distributed systems experience in production * Rust, or a strong systems background in another language like C++ or Go * Working knowledge of TypeScript Stack: Rust, TypeScript, FoundationDB, Postgres, ClickHouse, NATS, SQLite. ## **Benefits** * Health, dental, and vision insurance * 401(k) * Unlimited PTO
