Founding Engineer — Eleven
Eleven is looking for a Founding Engineer to build the first version of its mobile platform.
Initially, Eleven will be built and optimized for the Entrext ecosystem. This gives us a real environment to test the product, understand user behavior, improve the system, and build something that actually works before expanding it further.
Once the product is validated and optimized internally, the plan is to bring in a Growth Co-Founder to help take Eleven to a wider market and scale it beyond the Entrext ecosystem.
This means you will be responsible for building the technical foundation that Eleven grows on.
