Maximor AI — Staff AI Engineer

Type: Full-time | On-site | New York City, NY Compensation: $200,000–$250,000 + 0.1%–0.35% equity Hiring count: 1 Visa sponsorship: None Available Reports to: Founding engineering team

Maximor is building the AI operating system for the CFO office — connecting to a company's existing finance stack and automating the work behind the close, revenue recognition, reporting, cash management, and audit readiness. The goal isn't to help accountants write better prompts; it's for finance teams to review exceptions while audit-ready agents reason, explain their decisions, escalate uncertainty, and continuously improve. The company has raised $9M led by Foundation Capital, alongside Aravind Srinivas (CEO of Perplexity) and finance leaders from Ramp, Gusto, Zuora, and the Big Four.

• Org-wide leverage, not module ownership: Own the platform layer every engineering pod builds on — your work multiplies the output of the entire team.
• Strong seed backing: $9M led by Foundation Capital, with the CEO of Perplexity and senior finance leaders from Ramp, Gusto, Zuora, and the Big Four behind them.
• Ground-floor abstraction design: Define the agent harness, financial context graph, and verification standards that determine whether AI is safe enough to touch a customer's books.

Maximor is hiring a Staff AI Engineer to own the platform layer that every engineering pod builds on — from agent frameworks and context systems to orchestration, verification, observability, and data infrastructure. This is not a module-ownership role; the work multiplies the output of the entire engineering team, and the person is expected to identify the bottlenecks limiting the company rather than wait for specs from a PM or an architecture committee.

• →Own the agent harness the entire company builds on — abstractions for context, verification, guardrails, observability, and developer tooling so every pod ships audit-grade AI agents on shared rails.
• →Design and build the financial context graph: the structured layer every agent reasons over (ledger state, policies, contracts, precedent, entitlements) kept coherent, scalable, and multi-tenant safe.
• →Define the verification, auditability, evals, and observability standards that decide whether AI output is safe enough for a customer's books — and enforce them by construction.
• →Own the ingestion, normalization, reconciliation, and canonical ledger model that turns ERP, bank, billing, payroll, CRM, and email data into a trustworthy source of truth.
• →Design the durable execution layer for long-running AI workflows and the exactly-once, audit-ready path that safely writes back to ERPs and systems of record.
• →Build architectural primitives and frameworks that become the foundation other engineers depend on, compounding leverage across the org over time.

Tech stack: Python (primary), agent frameworks, distributed systems, workflow/transactional engines, data infrastructure. Fluent AI-coding-agent use (Claude, Cursor) valued.
