AI Engineer (Finance Systems & Integrations)

Part-Time (20 Hours/Week) | Remote | Opportunity to Scale Full-Time

About the company

They are a modern fractional CFO firm built for the next generation of consumer brands.

Rather than relying solely on spreadsheets or generic FP&A; software, they combine experienced finance professionals with custom AI-powered tools to deliver faster, more insightful financial operations for growing businesses.

Their clients are primarily emerging CPG, eCommerce, and consumer brands that need sophisticated finance support without building an internal finance department.

They are building proprietary technology—including automated cash flow forecasting, financial reporting, workflow automation, and AI-enabled finance tools—that will eventually become products in their own right.

They are looking for an experienced AI Engineer who wants to help build that future.

The Opportunity

This is not a traditional software engineering role.

You'll work directly alongside the founder to build the internal operating system powering a modern finance consultancy. You'll create tools that automate financial workflows, integrate financial systems, improve analyst productivity, and eventually become customer-facing software products.

You'll have significant ownership over architecture and technical direction while collaborating closely with finance professionals who deeply understand the business problems you're solving.

If you enjoy building practical AI applications—not just experimenting with prompts—but solving real operational problems with software, this role is for you.

What You'll Be Responsible For

Build AI-powered internal applications used by the finance team

Develop financial tools such as automated 13-week cash flow forecasting

Integrate with platforms including:

QuickBooks

Shopify

Banking APIs

Financial data providers

Design clean data pipelines and financial data models





Build workflow automation and ticketing systems for finance requests

Create tools that allow FP&A; professionals to deliver work faster

Ensure financial data quality through validation and reconciliation logic

Translate product specifications into scalable technical solutions

Recommend better architectures and technical improvements as the platform evolves

Collaborate daily with the founder to rapidly prototype and ship new functionality

What We're Looking For

Required

5+ years of software engineering experience

Experience building production AI-enabled applications

Strong experience with APIs and third-party integrations

Experience working with structured financial or accounting data

Ability to understand finance workflows—not just software development

Strong product thinking and problem-solving ability

Comfortable working in an early-stage startup with ambiguity

Excellent written and spoken English

Able to work EST business hours

Nice to Have

Experience with QuickBooks APIs

Shopify integrations

Banking APIs (Plaid, Stripe Financial Connections, etc.)

Accounting or FP&A; software experience

Workflow automation platforms

Experience building internal operational tools

Background working with finance, accounting, or consulting businesses

The Ideal Candidate

You don't simply build what you're told.

You understand the underlying business problem, ask thoughtful questions, and propose better technical solutions.

You enjoy working closely with founders, moving quickly, and building software that immediately creates value.

You're equally comfortable discussing architecture, debugging integrations, or improving internal workflows.

Why Join

Build a finance technology platform from the ground up

Work directly with an experienced founder and former CPG operator

High ownership and influence over product direction

Adaptable remote environment

Opportunity to grow into a full-time leadership position as the business scales

Build software that powers both internal operations and future SaaS products
