About Profound

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’ll shape the core primitives—execution, scheduling, state, and streaming—that power intelligent systems at scale.

Why This Role

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.

What You’ll Do

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.

Who You Are

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.

Pragmatic, collaborative, and product‑minded; thrive in a fast, in‑person environment.

Nice To Haves

Built or operated workflow engines, schedulers, or agent runtimes.

Experience with Postgres RLS and data governance at scale.

Practical exposure to containerization (Docker), CI / CD, and cloud environments.

Background integrating external AI / model providers and securing provider configs.

Tech Environment

Rust 2024, PostgreSQL, Redis

Kafka / NATS (streaming / messaging)

Containers and modern CI / CD

Real‑time streaming to clients

This Role Is Designed For

Builders who thrive on speed, iteration, and impact—working hands‑on with an in‑office NYC team.

Compensation

Base salary : $140,000 – $230,000. Total compensation includes salary, equity, and comprehensive benefits. Final compensation depends on skills, experience, and location, and will be determined during the interview process. Our recruiting team will share full compensation and benefits details as you move through hiring.

We’re happy to support visa sponsorship for qualified international candidates.
