System Architect, Workato

• Deep, hands-on Rust experience at a systems/backend level
• Working competence in Go - real production ability, though not necessarily your primary language
• Proven experience embedding Rust as a library or native extension inside another language's runtime (e.g. Rust-in-Ruby, Rust-in-Go)
• Strong algorithms and data-structures fundamentals (sorting, trees, data processing)
• Comfort operating without a fixed process methodology, in a deadline-driven, cross-team environment
• Experience with AI-assisted workflows, particularly in system analysis and hunting for inconsistencies and corner cases
• Scale: Experience with systems handling millions of requests/events per day
• Exceptional technical writing and communication abilities for diverse audiences
• Experience planning phased implementations and leading complex cross-team projects
• Proven track record with feature flags, gradual rollouts, and zero-downtime deployments
• Ability to facilitate architectural decision-making and create technical roadmaps
• Mentorship mindset and cost analysis capabilities

Desirable

• 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
