About the Role

Workato delivers enterprise infrastructure for the agentic era, redefining iPaaS and helping enterprises unify data, applications, processes, and AI into a single, governed platform. The Engine team owns three components used company-wide: Workato Expression Language, Data Mapper, and Decision Engine. The stack is a Rust core with WASM sandboxing per component, with bindings into Ruby and GO.

Responsibilities

  • 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.

Requirements

  • Deep, hands-on Rust experience at a systems/backend level.
  • Working competence in Go - real production ability.
  • Proven experience embedding Rust as a library or native extension inside another language's runtime.
  • Strong algorithms and data-structures fundamentals.
  • 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.
  • 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.
