About Us

eJam is a bootstrapped consumer products company that has built, scaled, and exited multiple brands — all without ever taking a dollar of outside capital. Our portfolio includes category leaders ranked at the top of Amazon, carried in major retailers nationwide, and sold across DTC, marketplaces, and every channel in between.

We're not a startup hoping something works. We're a team that has done it repeatedly — taken products from zero to eight figures, landed them on retail shelves nationwide, and built real brands that consumers love. We operate like a holding company with the speed of a startup: small team, no bureaucracy, massive ownership.

This is the place where you'll see the entire machine — sourcing, product development, packaging, manufacturing, compliance, marketing, marketplace strategy, retail — all under one roof. If you want to learn how consumer products actually get built and shipped at scale, there is no faster education than this.

About the Role

This is not just a coding job. It is for someone who wants to understand why things work, not just how to build them.
