Senior Product Engineer

The role We are looking for top 1% of full-stack engineers to join us in one of our 2 teams: Discovery: We build the intelligence layer behind Harmonic. Our system transforms hundreds of fragmented, unstructured sources - from APIs, raw HTML, legal filings, and more into structured knowledge about startups, investors, and people. We own the entire pipeline, from large-scale data ingestion to the full-stack search and research experience that surfaces breakout companies before anyone else.

On top of this foundation, we are developing an agentic research system that allows VCs to explore the startup ecosystem through natural language and structured queries, enabling faster sourcing, deeper diligence, and entirely new workflows for discovering breakout companies. Flow: Flow is Harmonic’s deal management system, built natively on top of our knowledge graph. Instead of forcing investors to sync data between a CRM and external sourcing tools, Flow makes Harmonic a first-class system of record.

VCs can manage deals, track companies, and collaborate directly within the platform. The result is the most intuitive and performant way to source, research, and triage opportunities in one place.
