Founding Engineer

About the Role Join a three-person founding team in New York building the full-stack systems behind an agentic platform that processes thousands of jobs daily in the capital markets intelligence space. As a Founding Engineer , you'll have an outsized impact on how the company makes its AI agents dependable — through reliable tooling, durable execution, and strong observability. You'll own work spanning frontend, data infrastructure, and AI orchestration from day one. This is a high-ownership, high-velocity role at the earliest stage. You're expected to inspect data, ship improvements, QA your own work, and fix things in production when they break. What You'll Do Work across the entire stack to ship frontend features, data pipelines, and agent infrastructure. Build real-time, customer-facing systems that keep users informed as information changes. Create internal tooling and data pipelines that enable analysts to add sources and maintain sector coverage faster and more reliably. Improve the tools and capabilities that make AI agents more reliable and capable in production. Own projects end to end: from data inspection and instrumentation through to shipping and production support. Ship meaningful contributions within your first days — add a new information source on day one, improve parsing and extraction within week one, and deliver a company ontology and the first version of a core product feature within 30 days. What We're Looking For Must-haves: A track record of having built, shipped, and operated production software systems end to end — at any experience level, including new graduates. Hands-on experience using AI agents or LLM-based systems to accomplish real work in production or substantial side projects. Experience building deterministic software tools and controls used alongside AI/agent systems. Backend service development with Python and FastAPI (or equivalent Python frameworks) in production. Database, data pipeline, and data infrastructure experience across relational and analytical data stores. Experience improving AI agent reliability, observability, or tool design for production agentic workflows. Frontend development with TypeScript and React , including real-time customer-facing features. Experience building parsing, extraction, or data reconciliation systems from unstructured or semi-structured sources. Cloud infrastructure and deployment experience with AWS, Cloudflare , or equivalent platforms. Sound judgment about when an AI agent should reason versus when deterministic software should take over. US work authorization required — visa sponsorship is not available. Nice-to-haves: Capital markets, financial data, or equity research domain experience. Experience with modern data stack tools such as dbt, Neon, MotherDuck, Turbopuffer , or similar. Experience with DBOS or durable execution frameworks. Experience building knowledge graphs, ontologies, or structured data models from unstructured information sources.
