About the Company

A venture-backed startup building an AI-native accounts receivable operating system for B2B distributors, with agents that handle credit decisions and collections end to end.

The Role

Our client is hiring hands-on engineers to architect and build systems that process millions of dollars in transactions daily, integrate with complex ERPs and use LLMs to transform how distributors manage revenue. You will own product end to end, from customer signal through spec, ship and measurement, on an AI-native team where Cursor, Claude Code and agentic workflows are part of daily work and everyone is a same-level individual contributor.

What You Will Do

• Build high-volume payment processing and secure financial APIs.
• Build deep integrations with major ERPs (NetSuite, Sage, Acumatica and others).
• Build LLM-powered workflows for credit decisions, remittance matching, automated communications and dispute resolution.
• Build real-time pipelines handling millions of financial records.
• Automate A/R and collections in ways that directly affect customer cash flow.
• Build evals, observability and guardrails that keep AI features safe in production.

What You Bring

• Full-stack shipping across frontend, backend, schema and tests
• Strong spec-writing and decomposition of work into clear, runnable pieces
• AI tools (Cursor, Claude Code) already part of your daily workflow
• A habit of talking to users and owning outcomes past launch
• US work authorization without sponsorship
