- Engine team owns three components used company-wide: Workato Expression Language (our original mini-language for data transformation in recipes), Data Mapper (a new, UI-oriented mapping and format-transformation component), and Decision Engine (a rules component, currently static-only, being expanded to support formulas)
- The stack is a Rust core with WASM sandboxing per component, with bindings into Ruby and GO
- Design and build core language and runtime features across the Expression Language, Data Mapper, and Decision Engine
- Own and extend the Rust core, embedding it as a native component inside Ruby and Go services via FFI bindings
- Help expand Decision Engine from static rules to support formulas
- Contribute to WASM sandboxing so each component runs safely isolated from the others
- Partner closely with Product and with the AI team on what these components need to expose
