Senior Backend Engineer (Rust) – Workflow Engines & Distributed Systems

On-site | Union Square, NYC

Full-time, Permanent

$Flexible Salary + Equity + Benefits

Build the execution layer powering the next generation of intelligent systems.

We’re building the foundational infrastructure that enables modern companies to orchestrate complex, multi-agent workflows with speed and reliability. Our core platform turns AI prototypes into production-grade, scalable workflows—and we’re looking for a Senior Backend Engineer to help build the engine that makes this possible.

This role is ideal for engineers who thrive on deep technical challenges: job orchestration, distributed state, real-time streaming, and secure multi-tenant environments. You’ll help define the core execution, scheduling, and state management primitives that underpin intelligent, autonomous systems.

What You’ll Be Working On

• Design and build Rust-first backend services for executing and managing graph/DAG-based workflows
• Own job orchestration systems with multiple execution modes: blocking, streaming, fire-and-forget
• Implement core features for idempotency, replay, backpressure, and retries
• Strengthen platform-wide tenant isolation, access control, and security
• Optimise PostgreSQL schemas, indexing, and query performance; own data migrations
• Ship reliable, observable systems with strong telemetry and operational tooling
• Partner with product, frontend, and data teams to ship production-ready features quickly

You Should Have

• Strong backend/system design experience, with production ownership
• Proficiency in Rust (or another systems language with willingness to ramp up)
• Solid SQL skills and experience with PostgreSQL or similar relational DBs
• Experience with distributed systems patterns: messaging, retries, idempotency, state
• Familiarity with Redis, real-time delivery (SSE/WebSockets), and pub/sub systems (Kafka or NATS)
• Understanding of auth/authz, multi-tenancy, and secure API design
• Comfortable working in a fast-paced, on-site environment with tight feedback loops

Bonus Points

• Built or operated workflow engines, schedulers, or agent runtimes
• Experience with Postgres RLS or data access control at scale
• Exposure to containerisation, CI/CD pipelines, and cloud infra
• Integrated external AI/model providers and secured API access/configs

Tech Stack Snapshot

• Rust 2024, PostgreSQL, Redis
• Kafka / NATS for messaging and streaming
• Docker, modern CI/CD
• Real-time API delivery to clients

Compensation & Benefits

• $Flexible base salary
• Competitive equity package
• Full benefits & perks
• Visa sponsorship available

This is an on-site role in Union Square, NYC. We’re building the execution backbone of AI-native infrastructure—and we’re looking for engineers who want to move fast, ship boldly, and shape the future of distributed intelligence.
