Job description

About us

Harmonic is the startup discovery engine.

It pains us to see great startup opportunities consistently go unfunded not because of lack of talent, but lack of signal.

We're fixing that by mapping the entire startup landscape and building the tools that put the right companies in front of the right people at the right time. Investors, corporate development, and GTM teams at Anthropic, OpenAI, General Catalyst, Kleiner Perkins, Brex and Notion use us to find breakout companies before they're obvious and turn that discovery into action. Whether that's a check, an acquisition, partnership or won business.

We’re growing revenue at a rate of 100%+ annually, backed by $30M from Craft, Floodgate, and Sozo Ventures. We're committed to ensuring hundreds of billions of dollars find the right founders, so the innovations that matters most flourish. If that resonates, let's talk.

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.

We’re specifically looking for engineers who have:

• 5+ years of full-stack software engineering experience, with flexibility for exceptional candidates. This role is 70/30 back-end leaning


• A record of shipping high-quality product. We’re excited to hear about the major releases you’ve driven over the past several years


• Experience quickly turning ambiguity into clarity - building scalable, performant, and observable frontend and backend systems from first principles while balancing technical, product, and organizational tradeoffs


• An interest in venture capital and the startup ecosystem
