Senior Software Engineer (Full-Stack)

Harmonic is the startup discovery engine.

It pains us to see great startup opportunities consistently go undiscovered every day. And it doesn't happen due to 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 and powering thousands of workflows. Backed by $30M from Craft, Floodgate, and Sozo Ventures, we're committed to using frontier technology to shine a light on private markets. If that resonates, let's talk. 

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. 

• 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
