We're building a new platform from scratch — a 0→1 product combining marketplace infrastructure, B2B SaaS, and high-volume content management, designed to handle significant transaction volume and billions of data points annually. This is a true full-stack role with roughly equal weight on frontend and backend. You'll own features end-to-end — from database schema through API design to the UI — working closely with our Staff Engineer, designer, and product stakeholders. Hands-on IC today, with a clear path toward technical leadership as the team grows.
