Riza | San Francisco | Full-Time | System, Backend, and Full-Stack Engineers | https://riza.io

We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.

Things we need help with:

- Our API (https://docs.riza.io/) (Postgres / Go)

- Our account dashboard (Postgres / Go / React / TypeScript)

- Our code execution engine (Go / Rust)

- New products including code generation workflows (Anthropic / OpenAI experience a plus)

We’ve raised seed money, but the whole company is currently just me, Andrew and David working out of a converted warehouse on Alabama St. We’re second-time founders, so we know the risk we’re asking you to take and we’re prepared to compensate accordingly.
