We are looking for a high-level Lead Engineer to spearhead a 5-7 day sprint for our Fintech SaaS. The product is built (Next.js/TS/PostgreSQL) and uses a multi-LLM pipeline to convert complex PDFs into structured data. We need a lead who can bridge the gap between document processing and structured CRM/Lead Management output. This is not a greenfield project. The infrastructure is live; your job is to lead the final push to resolve blockers before monetization. Technical Description Our core engine uses Google Document AI and a multi-LLM pipeline (Claude/GPT) to extract financial data. We need to optimize the data flow to ensure that lead-related information and financial schedules are mapped perfectly from PDF to our UI and Excel exports.
