You will build core workflow engine primitives to orchestrate agents, tools, and dataflows. You will design and ship Rust-first backend services and own the real-time control plane.

What you will do

• Build core workflow engine primitives used to orchestrate agents, tools, and dataflows
• 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

• Experience with distributed systems patterns including messaging or streaming, retries, idempotency, and backpressure
• Familiar with caching and state systems such as Redis and real-time delivery using SSE or WebSockets
• Strong grasp of API authentication and authorization, multi-tenancy, and security best practices
• Pragmatic, collaborative, and product-minded, thriving in a fast, in-person environment

Nice to have

• Experience building or operating workflow engines, schedulers, or agent runtimes
• Experience with Postgres RLS and data governance at scale
• Practical exposure to containerization, CI or CD, and cloud environments
• Background integrating external AI or model providers and securing provider configurations
