The Role

Block is scaling Customer Insights into an AI-powered insights accelerator that enables product and GTM teams to move at AI‑first speed. We're seeking an AI Research Infrastructure Engineer to architect and build the intelligent systems powering this transformation by designing AI agent ecosystems, automated data pipelines, and agentic workflows that compress research cycle times while maintaining methodological rigor. You'll build research infrastructure from the ground up, working at the intersection of AI / ML, research methodology, and data engineering. You'll enable Block to access research & insights at the speed of decision‑making. You are a technical builder who combines deep automation expertise with research domain knowledge, is comfortable working in a rapidly changing environment, and wants to define what an AI‑powered research organization looks like at scale.

You Will

• Design, build, and deploy AI agents and agentic workflows that automate research operations from study design through insights delivery, using LLMs, prompt engineering, MCP (Model Context Protocol) integrations, and workflow orchestration integrated with existing research and analytics tech stack.
• Design, build, and maintain automated data pipelines that ingest, transform, and unify research data from diverse sources (surveys, transcripts, analytics, behavioral logs) into AI‑ready repositories with RAG capabilities for instant insight access via tools like Goose.
• Architect ETL / ELT frameworks using Python, SQL or equivalent tools to ensure data consistency, traceability, and scalability.
• Develop data models and schemas for research metadata, participant data, and AI‑generated insights to support efficient querying and analysis.
• Design and prototype research automation systems using AI / ML techniques, partnering with design & engineering teams to productionize solutions.
• Partner with engineering, design, and platform teams to integrate research automation systems with Block's tech stack (i.e. Goose, GitHub, etc.) and establish governance frameworks for quality, ethics, and compliance.
• Mentor team members on AI agent development, agentic system design, and research automation best practices to build organizational capabilities in intelligent automation.
