AI Engineer - Payments & Processing

The Mission

We're building an AI-powered insurance brokerage that's transforming the $900 billion commercial insurance market by automating transactions, financing agreements, and revenue management.

We just finished YC and are emerging from stealth with $8M in funding from an amazing bench of investors. We're looking for an exceptional AI Engineer who will architect AI-driven transaction systems that power our sales and payments infrastructure.

You'll create systems that automate the entire financial lifecycle of insurance policies, from document generation to e-signatures, premium financing, payment processing, and revenue attribution. This role sits at the critical intersection of engineering, AI, and fintech—a position to directly impact revenue as we scale from seed to industry leader. You will work directly with the CEO and CTO to shape our transaction automation strategy and technical roadmap.

Be bold & aggressive enough to believe we can scale from $1.2M to $100M in run-rate ARR by December.

Outcomes You'll Drive

• Build AI agents that orchestrate document generation, e-signing, and financing using web agents and API integrations
• Develop multi-modal payment infrastructure integrating Stripe, Finix, Plaid (ACH), and financing company APIs for seamless payments via voice, email, text, and online
• Implement AI models to track and optimize revenue from sales transactions, including broker fee management
• Create automated systems for premium financing agreements and build AI agents that navigate non-API-based financing company portals
• Architect solutions for handling installment payments, cancellations, and refunds with minimal manual intervention
• Develop invoicing and document management systems to track executed insurance policies and carrier-issued documents
• Collaborate with the frontend team to build a self-service portal for customers to execute transactions, track policies, and manage payments
• Implement real-time notification systems to ensure seamless execution of sales, payments, and document workflows

• You've worked with payment platforms like Stripe, Finix, Plaid, and financing systems
• You thrive at the intersection of engineering, AI, and financial operations
• You're proficient with modern coding environments like Cursor or WindSurf IDE for maximum productivity

Hard Requirements
