Descripción de la vacante

Workato is seeking an experienced systems/software engineer to design and evolve core components including a Rust-based runtime, WASM sandboxing, and language bindings. You will collaborate with product and AI teams to shape exposure, interfaces, and reliable architectures across multiple components.

Ideal candidates bring deep Rust knowledge, production Go experience, and a track record embedding Rust as a library in other runtimes.

Formación

• Strong algorithms and data-structures fundamentals are required.
• Proven hands-on Rust experience at a systems/backend level.
• Working knowledge of Go in production environments.
• Experience embedding Rust as a library or native extension.
• Familiarity with WASM sandboxing and related tooling.

Responsabilidades

• 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 inside Ruby and Go services via FFI bindings.
• Help expand the Decision Engine from static rules to support formulas and automation.
• Contribute to WASM sandboxing to keep components isolated and secure.
• Partner with Product and AI teams to define exposure and interfaces.

Descripción del empleo

• 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
