Fractional Founding Engineer — Santa Clara, CA

COMPANY DESCRIPTION

nmvGXr4t provides AI-powered audits that match contracts to invoices to find billing leakage across carrier, property management, and vendor invoices. The platform identifies discrepancies, drafts recommended corrective actions, and turns approvals into a one-click workflow. By automating complex back-office checks, nmvGXr4t helps organizations recover measurable savings and reduce risk.

Our founder has 10+ years in logistics and e-commerce fulfillment, most recently as the founding PM of Fulfillment by TikTok. We have 1 live customer, with 1-2 more expected in the next 2 months. Our current product was built with no-code and AI tools and is validated on real invoices and contracts. Now we need real engineering rigor behind it.

ROLE DESCRIPTION

We're looking for a Fractional Founding Tech Lead, about 10-15 hours a week, remote-friendly. You will own:

- Architecture and technical direction for the product

- Test coverage and correctness of the matching engine

- Security basics for handling customer financial documents

- Integrations with billing and accounts-payable systems

- Practical guidance as we scale the build, including early technical hiring decisions

The deal: 1-2% equity [with 4-year vesting and a 1-year cliff], equity-only for now. As soon as we sign 4-5 contracts, there's an option to move to full time with CTO-level equity.

QUALIFICATIONS

- Have built and shipped production software, hands-on (Python, TypeScript, or similar)

- Experience with data pipelines, rules engines, or LLM-based document extraction

- Understand cloud infrastructure and security and reliability fundamentals

- Comfortable reviewing and hardening AI-generated code

- Early-stage startup experience; fintech, procurement, or AP/audit experience is a plus

- Clear communicator who can explain technical decisions to non-technical teammates

- Bachelor's degree in Computer Science or a related field, or equivalent practical experience
