$180K-$220K Base + Meaningful Founding Equity (Up to 1%+)

We're partnering with a venture-backed AI company transforming how multi-site organizations leverage financial intelligence.

What You'll Do:

• Design and build production-grade AI agent systems from the ground up.
• Own orchestration, planning, memory, retrieval (RAG), tool-calling, evaluation, and guardrails.
• Develop agents that reason across structured financial data, documents, APIs, and business workflows.
• Connect AI systems to internal platforms, databases, and third-party applications.
• Build validation and reliability frameworks that improve accuracy and trustworthiness.
• Partner directly with founders to shape product strategy and technical architecture.

What We're Looking For:

• 5+ years of software engineering experience.
• Personally built and shipped a complete AI agent system used by real customers.
• Deep experience with LLM orchestration, RAG, structured outputs, function calling, and evaluation frameworks.
• Strong TypeScript skills.
• Experience operating in startup environments with high ownership and ambiguity.
• Strong systems design and architectural judgment.

Strong Plus Factors:

• Former founder or founding engineer.
• Experience building accuracy-critical AI applications.
• Mastra framework experience.
• Background in fintech, healthcare, analytics, enterprise SaaS, or other structured-data environments.

Why Join:

• Founding-team opportunity with significant equity.
• Direct partnership with experienced repeat founders.
• Backed by leading venture investors with multi-year runway.
• Real customer traction and market demand.
• Opportunity to define the AI architecture and roadmap from day one.

Location: Remote (U.S.) with occasional travel for team collaboration.

If you've successfully built production AI agents that real customers depend on and want to help define the future of AI-powered business software, we'd love to connect.
