Founding Engineer

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.

• 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.

• Salary: $150,000 - $175,000 USD annually
• Founding team equity
• High-impact, high-ownership role at the ground floor of a fast-moving company
