SWE Backend (Workflow Runner)

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

Own the real-time control plane: 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/DAG workflows.

Build reliable job orchestration with multiple response modes (blocking, streaming, fire-and-forget) and durable state.

Strengthen tenant isolation, security, and access patterns across the platform.

Improve runtime behavior: scheduling, backpressure, timeouts, retries, and idempotency.

Evolve schemas and repositories; own migrations, indexing, and query performance.

Instrument with meaningful telemetry; raise the bar on testing and operational excellence.

Partner closely with product, frontend, and data teams to deliver high-impact features.

Strong portfolio or GitHub showing backend/system design depth.

Proficient in a modern systems language (Rust ideal); comfortable owning services end-to-end in production.

Solid with SQL and relational data modeling; hands-on with PostgreSQL.

Experience with distributed systems patterns: messaging/streaming (Kafka or NATS), retries, idempotency, backpressure.

Familiar with caching/state systems (e.g., Redis) and real-time delivery (SSE/WebSockets).

Strong grasp of API authn/authz, multi-tenancy, and security best practices.
