AI Engineer - Payments & Processing

Harper is an innovative AI-native commercial insurance brokerage that's revolutionizing the $900 billion commercial insurance market through automated transactions, financing agreements, and revenue management. Fresh out of Y Combinator and backed by $8M in funding, they're seeking an exceptional AI Engineer to architect their AI-driven transaction systems.

The role focuses on creating sophisticated systems that automate the entire financial lifecycle of insurance policies, from document generation to e-signatures, premium financing, payment processing, and revenue attribution. Working directly with the CEO and CTO, you'll be instrumental in shaping the company's transaction automation strategy and technical roadmap.

The tech stack is comprehensive and modern, including LangGraph for AI agent orchestration, various LLMs (Claude, GPT-4), payment processing integrations (Stripe, Finix, Plaid), and a robust data infrastructure using PostgreSQL, Redis, and modern analytics tools. The role requires expertise in both TypeScript/Node.js and Python/ML frameworks, with a strong focus on shipping features daily and driving measurable revenue impact.

The ideal candidate will have experience with transactional AI systems in fintech or insurtech, multi-modal payment processing, and agent orchestration systems. The role offers an opportunity to work at the intersection of engineering, AI, and financial operations, with a clear focus on scaling the company from $1.2M to $100M in run-rate ARR.

The first 90 days will involve implementing AI-driven document workflows, setting up payment processing systems, developing automation for financing agreements, and building self-optimizing revenue models. This is an excellent opportunity for someone who thrives in a fast-paced startup environment and wants to make a significant impact in the insurtech space.
