Experteer Overview In this role you will design and extend core runtime features for the Engine trio: Expression Language, Data Mapper, and Decision Engine. You will embed Rust as a native component inside Ruby and Go services, and evolve the Decision Engine to support formulas. You’ll help harden WASM sandboxing so components run in isolation while collaborating closely with Product and AI teams. This is a hands-on opportunity to shape high-performance, scalable infrastructure that powers real-time automation at scale. You’ll join a collaborative, innovation-driven culture focused on trustworthy, enterprise-grade solutions.Compensaciones / Ventajas
