About The Company
Stampli is the stress-free finance operations platform. Its AI-driven procure-to-pay solution runs processes from request through payment while remaining fully aligned to the ERP as the system of record, mirroring charts of accounts, entities, dimensions, and approval hierarchies without requiring ERP rework or forcing teams into rigid process models. Rather than adding AI on top of legacy infrastructures, Stampli has embedded intelligence directly into how work happens since being founded in 2015. Stampli AI operates across the full procure-to-pay lifecycle to extract data, code transactions, route approvals, match invoices, handle exceptions, and preserve institutional knowledge. That intelligence has been trained on billions of real-world transactions across $150 billion in annual spend, continuously improving with every correction across thousands of customer environments. The platform delivers end-to-end capabilities across procurement, accounts payable, vendor management, payments, and corporate cards. More than 1,800 businesses trust Stampli to process their finances accurately and efficiently. As volume, entities, and complexity increase, Stampli absorbs growth without proportional headcount, driving faster processing, leaner operations, and smarter spending with full visibility, control, and audit-ready accuracy.
About the Role

We’re hiring a ML Engineer to accelerate AI-driven innovation across Stampli’s B2B SaaS platform.

You’ll be at the forefront of building intelligent systems that power core product experiences and automate internal operations, driving efficiency, speed, and scale across the organization. This is a high-impact, hands-on role in a fast-growing, AI-first company where machine learning is a foundational pillar, not a bolt-on feature. You'll partner with product, engineering, and operations teams to design and implement powerful ML and LLM-based solutions that make a measurable difference.
