Founding Engineer

About the Role

This is a founding engineering role at an AI-native fintech company building autonomous systems to manage complex financial transactions end-to-end. You will own the technical core of a product that coordinates multi-party financial workflows, models businesses, and reasons about markets at scale. Your decisions will define the architecture and capabilities of the platform from day one.

What You'll Do

• Build intelligence that models businesses, reconciles contradictory evidence, and reasons about how decisions propagate through companies and markets.
• Design and ship agents that coordinate months of financial work across hundreds of counterparties, preserving context, commitments, and dependencies as conditions change.
• Own end-to-end architecture, evaluations, infrastructure, and product interfaces for complex AI systems.
• Help select technical teammates and establish engineering and operating standards for the team.
• Move fluidly across backend systems, applied AI, and product interfaces to turn ambiguous problems into working products.

What We're Looking For

• 8 or more years of experience shipping difficult, production-grade systems and owning critical technical decisions.
• Deep expertise in applied AI, including building intelligent agents and models for complex business processes.
• Experience with AI components such as retrieval, memory systems, and evaluation frameworks, especially in data-intensive environments.
• Proven ability to own end-to-end architecture and infrastructure for complex AI systems.
• Full-stack AI engineering capability: comfortable working across backend, applied AI, and product layers.
• Strong commitment to engineering craftsmanship, system reliability, and measuring whether systems actually work.
• Experience building in greenfield or first-principles environments is a strong plus.
• Background in financial services, investment banking, or other complex professional workflows is an advantage.
