• Integrate banking-as-a-service partners, payment rails, card and lending systems, and KYC and AML services
• Design secure, resilient architecture for an agentic financial-services platform
• Build agentic workflows that make real-money decisions with deterministic logic, auditability, and compliance guardrails
• Select cloud, data, observability, disaster-recovery, and security approaches from first principles
• Set engineering standards for future hires while coordinating with contract engineers
• Ship production systems quickly without compromising trust, reliability, or regulatory requirements Requirements
• 5 or more years of full-stack software-engineering experience
• A track record of building and shipping a product from zero to one for real users
• End-to-end ability across React or React Native, TypeScript, backend services, Python, and cloud infrastructure
• Hands-on experience building or deploying AI agents or agentic workflows in production
• Experience owning architecture for secure, reliable production systems
• Strong product judgment, bias for action, and comfort operating as the first technical hire
• Ability to work regularly from New York City or San Francisco within 12 to 18 months Bonus points
• Experience at a US fintech startup in neobanking, banking-as-a-service, cards, lending, or payments rails
• Experience with KYC, AML, money movement, regulated data, or consumer financial products
• Familiarity with LLMs, retrieval-augmented generation, and production AI safety patterns
• A computer-science or other technical degree
• Interest in growing into a technical leadership and management role Benefits
• Base salary of $150K-$300K
• Founding-team equity of 1% to 4%
• Exceptional scope and direct influence over product, architecture, and company direction
• Visa transfers, OPT, and H-1B sponsorship may be available for exceptional candidates
• Remote-first for the first 12 to 18 months
• Transition to regular in-person or hybrid work in New York City or San Francisco after that period
• Full-time founding-team position
