The Partner Platform team owns the foundational systems that power partner integrations at Parafin. We build and operate partner data ingestion pipelines, DAG-based processing systems, public APIs, durable webhook delivery infrastructure, sandbox environments, and partner-specific integrations. We collaborate across engineering and data teams to ensure partner data reliably powers underwriting, risk evaluation, and reporting workflows. Our roadmap includes major platform modernization efforts, including evolving our data architecture and strengthening the reliability and scalability of our asynchronous, event-driven systems. The ideal candidate will thrive in a fast-paced environment, demonstrating strong technical fundamentals, the ability to navigate ambiguity and take ownership of projects from inception to completion.
