Technical Co-founder (CTO) - AI Collections Agent

Argentl is building an AI collections agent for B2B finance teams. The Co-Founder & CTO will own product and engineering, take the product from live pilots toward reliable production deployment, and lead the technical direction, team, and customer-facing technical work.

Responsibilities:

• As Co-Founder & CTO, you will take over the production code and continue building the product (the first lines of production code), set the technical direction, and lead execution end-to-end
• Architecture & Reliability — Harden the voice and workflow systems for in-production reliability. Establish core architecture, observability, and audit-trail standards for a product that speaks to customers' debtors on their behalf
• Delivery Layer — Build the internal infrastructure that lets the team configure, monitor, and optimize agent performance without scaling engineering headcount. Mature the workflow engine so every call, intent classification, and next-action flows through reliably
• Integrations & Distribution — Own the accounting and ERP integration layer (QuickBooks, Xero, and beyond) that turns Argentl from a CSV upload into an embedded part of the finance stack — the primary distribution unlock
• Unit Economics — Own the trade-offs between AI quality and cost-per-call, and lock in unit economics within a productized monthly pricing model
• Customer & Market — Represent the company in front of finance leaders, partners, and investors as the technical voice of the venture
• Roadmap — Convert pilots into paying customers, expand the AI staff beyond collections, and begin a path toward custom and self-hosted models where data-privacy and financial-compliance requirements demand it
• Team — Recruit and lead the founding engineering team, and establish the cultural foundation of the company
