Experienced AI Engineer, Accounting & Tax Automation (AI Agents, LLM Systems)

We build AI systems for accounting and tax firms in the US, and we're growing our engineering team. We're looking for experienced AI engineers who have built real AI and automation systems, ideally for accounting, tax or finance teams, and who want to work with us long term. This is not a one-time contract. We work project by project, based on demand from the firms we work with, and we want the right engineers on our side for that. Right now we're finding those people. Not for beginners. Years don't matter as much as real work: only apply if you've built AI systems that real teams use in production. Location: we're prioritizing engineers based in the US, and also open to strong engineers in India. Pay: we pay fairly for good work. Rates are discussed and agreed per project, hourly or fixed, before any work starts. What we're looking for: - Production AI systems: LLM-based apps, AI agents, multi-agent orchestration, tool/function calling - Workflow automation end to end: from raw documents to finished output, with the steps in between - Document AI: PDFs, scans, OCR, structured extraction with LLMs - RAG, prompt design, evals and accuracy testing on real data - Human-in-the-loop design: confidence scores, exception queues, review steps, audit trail - Integrations with accounting/tax software (QuickBooks, Xero, CCH, UltraTax, Lacerte, Drake or similar) and APIs - Python, strong backend skills, cloud deployment - Clear English, comfortable on a call with a firm owner Big plus: you've worked with accounting, tax or finance workflows before (1099s, K-1s, workpapers, GL, reconciliations). In your proposal, please include: 1. Links to your real projects (live link, GitHub, Loom, screenshots or case study) 2. For each one: what the team did by hand before, what you built, your exact role, and the result 3. Your AI stack: models, frameworks (LangChain, LangGraph, CrewAI, custom, etc.), infra 4. How your system handles an output the model isn't sure about 5. Accounting or tax software you've integrated with 6. Where you're based and your availability in US hours 7. Your usual hourly rate Start your proposal with the word "ledger" so we know you read this. Generic or copy-paste proposals, and proposals without real project links, will be skipped.
