Co-founders:

Engineering & Product Lead - Senior technologist with a proven track record of building and scaling widely adopted SaaS products, including prior involvement in the development of a globally recognized scheduling platform. Markets & Distribution Lead - Experienced growth and distribution specialist with a substantial digital audience (multi-million subscriber base), and founder of a product operating in the trading and analytics space, demonstrating established market reach and user acquisition capabilities. What we're building TradeTerm is the audit-first replay platform that prop firms, Tradezella users, and serious futures traders have been missing. Bookmap-class orderflow UX, with audit + replay + execution as the wedge. Distribution is locked from day 1: Umar's 4M-sub launch channel + warm Tradezella audience — not "build for a year then maybe." What you'll get Real ownership . Spec → plan → build → ship. No ticket queue. Skin in the game . Trade on the platform you build. Eat your own cooking. AI-first, true team. You'll work with people who use AI as a research / planning / execution stack — not as a copilot. The kind of disciplined workflow most engineers spend years figuring out alone. Market comp + broad geo. Cash comp at market rate. Hiring globally. Fluid working style . We pair when it accelerates the work. We go async / deep when the work needs it. No ceremony — output > activity. Who we're hiring A senior full-stack engineer who is •also an active trader•.
