Senior Software Engineer, Workflow Engine

ABOUT PARAGON Paragon is an integration infrastructure platform for B2B SaaS & AI products. We help companies build, ship, and operate integrations inside their products without needing to own all of the underlying integration complexity themselves. Our Workflow Engine product gives customers a flexible platform for building event-driven automations across their integrations and internal systems. It powers workflows that react to external events, evaluate conditions, orchestrate actions, and execute reliably across distributed systems at scale. ABOUT THE ROLE We’re hiring a senior backend engineer to join our Workflow Engine team. You’ll be one of the key engineers shaping the architecture, reliability, and evolution of one of Paragon’s core products. You’ll work across our backend stack - TypeScript (NestJS), Postgres, Redis, Kafka, and Kubernetes - to build and operate the systems that power workflow execution end-to-end. That includes ingesting and processing events, evaluating triggers and conditions, managing workflow state, orchestrating async execution across steps, and ensuring workflows run reliably under retries, failures, and bursty production traffic.
