Compensation: $170,000–$220,000 + equity

About the Company

A seed-stage startup building the AI operating system for the CFO office — audit-ready AI agents that connect to a company’s existing finance stack and automate the full order-to-cash, record-to-report, treasury, and financial-reporting workflow, so finance teams review exceptions while AI handles the rest. Venture-backed by leading investors and experienced finance operators.

The Role

Own a finance domain end-to-end — from context engineering and prompt design through tool use, evals, guardrails, and the UX around them — working directly with controllers, accountants, and CFOs to replace manual processes with production-grade agent systems. This is a backend-heavy, full-stack-in-practice role: no PM writes your specs and no architecture committee gates your ideas.

What you’ll be doing

• Own a finance domain end-to-end, building the agent system that automates it across context, prompts, tools, evals, guardrails, and UX
• Design and implement durable, replay-safe orchestration for long-running AI workflows across flaky, stateful enterprise systems
• Build the trust layer for non-deterministic systems: evals, verification, guardrails, and observability that catch agent mistakes before a human does
• Ship full-stack when the work calls for it, owning decisions across the LLM pipeline, infrastructure, backend, and UX within your pod
• Do serious context engineering: retrieval, memory, and tool design over large, messy, proprietary financial data
• Build idempotent, audit-ready write-back systems for ERPs and financial systems with full traceability

Tech stack: Python (primary stack)

Requirements

• 2+ years building and shipping production AI agents
• 4+ years backend or infrastructure engineering
• Research background in ML, NLP, or AI agents
• Early-stage startup experience (pre-seed to Series B)
• NYC in-person, startup hours, 6 days a week, 9am to 7pm or 8pm

Green Flags

• Strong agentic systems track record
• Research background in ML, NLP, or agents
• Graduated post-2021 with direct agentic-era experience
• Fintech, ERP, or accounting software background

Red Flags

• Frontend-heavy background with little backend depth
• Generic AI resume without architectural depth
• Multiple short tenures

Why Join

• Own a finance domain end-to-end with no PM gating your specs and no committee gating your ideas
• Work on hard, novel problems: trustworthy agents for finance and audit, context engineering over messy financial data, durable orchestration across flaky enterprise systems
• Meals and stocked NYC office, 401(k) with employer match, and full medical, dental, and vision for employees and dependents
