Job Description:

Our core platform turns AI prototypes into production-grade, scalable workflows.

Job Responsibility:

  • 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

Requirements:

  • 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

Nice to have:

  • 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
What we offer:
  • Equity
  • Full benefits & perks
  • Visa sponsorship available
