Job description

Build AI agents that power real fintech operations.

We're building AI agents that don't just answer questions; they automate critical operational

work for fintech companies, from reconciliation and onboarding to customer support and

financial analysis. These systems run in production, make decisions that matter, and are trusted

by paying customers every day.

We're looking for a Senior Full-Stack AI Engineer who thrives in ambiguity, loves building from

scratch, and wants to shape the next generation of AI products alongside an experienced

founding team.

What You'll Do

• Own AI features and products from idea to production with end-to-end responsibility.
• Design and build LLM-powered agents, including prompt engineering, tool orchestration, evaluations, and guardrails.
• Develop across the full stack using TypeScript and Node.js.
• Turn loosely defined problems into scalable, customer-ready solutions.
• Work directly with the founders to build technology that solves real business problems.
• Ship quickly, iterate based on customer feedback, and continuously improve AI reliability.

What We're Looking For

• 8+ years of professional software engineering experience.
• Deep experience building production applications with TypeScript and Node.js across the full stack.
• Proven experience shipping LLM-powered products into production.
• Daily user of AI coding tools (Claude Code, Cursor, GitHub Copilot, etc.) with the ability to evaluate and improve AI-generated code.
• Strong startup background with a track record of owning products end-to-end.
• Comfortable making decisions with limited direction and delivering independently.
• Passion for building new products rather than maintaining legacy systems.

Nice to Have

• Experience building AI agents, RAG systems, or evaluation frameworks.
• Fintech or other regulated industry experience.
• Founding engineer or early startup experience.
• Cloud infrastructure, CI/CD, and DevOps ownership.

Why Join Us

• Build truly novel AI technology. You'll work on AI agents that businesses depend on, not demos or prototypes.
• Real customer impact from day one. Your work will be deployed to paying customers within weeks.
• High ownership. You'll make architectural decisions and own products from concept to
• Learn from an exceptional founding team. Our founders bring expertise from Google, McKinsey, Dow Jones, Fortinet, and one of the engineering teams behind a leading AI company in a regulated industry.
• Meaningful equity. Join early and help shape both the product and the company.
• Backed by leading fintech and enterprise investors with strong traction and growing
