Growth Product Manager (PLG)

About Higgsfield Higgsfield.ai http://Higgsfield.ai is the fastest-growing generative AI platform in the world. Creators use Higgsfield to produce video, images, and interactive content with 200+ frontier models — and they do it at a scale few consumer products ever reach: we grew revenue 3x in the last four months and crossed $700M in annualized GAAP revenue by July 2026. We recently closed a $500M funding round at a $5B valuation to accelerate what's working. The company is small relative to its revenue, decisions are fast, and the distance between an idea and production is measured in days - we ship 80+ releases a month. About the role You will own product-led growth at Higgsfield: making the product itself our biggest acquisition channel. Referral mechanics, viral loops, shareable artifacts, and agentic distribution — we were among the first in the world to sell subscriptions directly inside AI assistants via MCP, and that channel already drives a meaningful share of our new plan purchases. Your job is to engineer growth that compounds without a marketing budget. We are looking for a builder, not an optimizer. There is no PLG playbook for consumer AI — you will be writing it. You should be comfortable shaping strategy without precedent, shipping daily, and defending your calls with numbers. This is a hands-on A-level role with founder-level visibility, on the Product Growth team — the team that owns all of Higgsfield's revenue. Key responsibilities • Design and ship referral mechanics end-to-end: incentive structures, anti-abuse, unit economics per referral, GAAP-compliant reward design — prioritizing defensible economics over headline signup numbers. • Build viral loops into the product: shareable generation artifacts, watermark-to-signup flows, social-embedded distribution — so that every piece of content our users publish works as acquisition surface. • Own the mobile PLG motion — desktop is our revenue platform; mobile is our acquisition engine.
