Client is automating compliance for banks and fintechs using AI agents that function like human analysts within browsers. The company is experiencing rapid growth and is expanding its engineering team to accelerate development and meet an ambitious 6-month roadmap. Clients AI agents automate AML, KYC, KYB, and transaction monitoring, targeting a $50B+ market currently dominated by manual compliance labor. The company is led by founders with a track record of building and selling successful AI and ML systems.

• Has never lost an RFP to a competitor.
• Used across the U.S., Canada, Europe, and Lat Am.
• Delivers 90% less manual work and 4× lower costs to customers.
• Run by founders who previously sold an AI company and built ML systems used by millions.
• Operates in a high-velocity, customer-focused, no-nonsense environment.

As a backend engineer, you will build and maintain the backend and ML systems powering Client's AI agents. These systems navigate the web, interpret unstructured data, detect global financial risk, and make sub-second compliance decisions.
