Profound is building the foundational agentic layer for modern companies. Our Workflow Runner is the execution backbone that turns complex AI work into reliable, composable workflows. You will shape the core primitives, execution, scheduling, state, and streaming, that power intelligent systems at scale.

Own the real-time control plane, including streaming events, reliable job orchestration, idempotency, and replay
Ship high-leverage systems that turn prototypes into production-grade, scalable workflows
Design and ship Rust-first backend services and clean APIs for creating, executing, and supervising graph or DAG workflows
Build reliable job orchestration with multiple response modes, including blocking, streaming, and fire-and-forget, with durable state
Strengthen tenant isolation, security, and access patterns across the platform
Improve runtime behavior including scheduling, backpressure, timeouts, retries, and idempotency
Evolve schemas and repositories and own migrations, indexing, and query performance
Instrument with meaningful telemetry and raise the bar on testing and operational excellence
Partner closely with product, frontend, and data teams to deliver high-impact features
