Job Description

<div class="content-intro"><h2><strong>About us</strong></h2> <p>Harmonic is the startup discovery engine.</p> <p>It pains us to see great startup opportunities consistently go undiscovered. So, we dedicated ourselves to mapping out the startup landscape and building the tools that ensure the most promising founders get found and funded.</p> <p>The world's largest and most prolific venture capital firms (as well as the up-and-comers you haven’t heard of yet) rely on us to find and invest in the next Google, AirBnB, Uber, Stripe, and Anduril. We play a crucial part in ensuring hundreds of billions of dollars get routed efficiently and that the innovations the world would most benefit from materialize.</p> <p>We’re growing revenue at a rate of 100%+ annually and already power thousands of investors' workflow. Backed by $30M from investors like Craft, Floodgate, and Sozo Ventures, we want to power the entire investment workflow from discovery to term sheet. If you resonate with <a href="https://www.harmonic.ai/careers">our values</a> and want to fundamentally evolve how venture capital markets work, come join us.</p></div><h2><strong>The role</strong></h2> <p>We are looking for top 1% of full-stack engineers to join us in one of our 2 teams: </p> <ul> <li><strong>Discovery</strong>: 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. </li> <li> <p class="p1"><strong>Flow</strong>:<strong> </strong>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.</p> </li> </ul> <p><strong>We’re specifically looking for engineers who have:</strong></p> <ul> <li>5+ years of full-stack software engineering experience, with flexibility for exceptional candidates. This role is 70/30 back-end leaning</li> <li>A record of shipping high-quality product. We’re excited to hear about the major releases you’ve driven over the past several years</li> <li>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</li> <li>An interest in venture capital and the startup ecosystem</li> </ul> <p><strong>Pay:</strong></p> <p>$180k-$220k Salary + Equity depending on the level</p> <h2>Our stack</h2> <p><img style="max-width: 100%;" src="https://i.imgur.com/cWOMCzl.jpg" alt="Job Description Image"></p> <h2>The Process</h2> <p>Here’s our interview process:</p> <ol class="p-rich_text_list p-rich_text_list__ordered" data-stringify-type="ordered-list" data-indent="0" data-border="0"> <li data-stringify-indent="0" data-stringify-border="0">Recruiter Screening: 20 mins</li> <li>Technical Screening (Debugging): 45 mins</li> <li data-stringify-indent="0" data-stringify-border="0">Technical Screening (System Design): 45 mins</li> <li data-stringify-indent="0" data-stringify-border="0">Technical Screening (Coding): 2 hrs </li> <li data-stringify-indent="0" data-stringify-border="0">Behavioral interview with Head of Eng: 30 min</li> <li data-stringify-inden ...
