About The Position

Mechanism builds profitable companies and turns them into enterprises. Since 2019, we’ve launched and scaled 10 companies while driving $200M+ in revenue by treating company-building as an engineering problem, not an art project. We combine rigorous validation, advanced analytics, and repeatable systems to dramatically increase the odds of success. Today, we are pushing that model further: building an operating system for entrepreneurship that allows us to launch profitable, reinvesting companies with speed, precision, and minimal waste. This role sits at the center of that system. The Growth Engineer owns growth for HeySunday. HeySunday is not just another brand in the portfolio. It is one of Mechanism’s two profit companies, and it helps fund the rest of the operating system. The profit from HeySunday gives us room to launch new companies and keep building for the long term. This means you are responsible for growth and the work that goes into it. You will set the strategy, manage the channels, run the experiments, understand the math, and make the calls on where we push, where we cut, and what we try next. This is not a role for someone who wants to hand paid media to an agency and check in once a week. It is not for someone who wants to stay high-level while someone else is inside the accounts. It is for someone who wants to sit at the center of our growth engine, be hands-on daily, and have real impact. Most of your time will be spent on HeySunday, roughly 80%. The rest will be spent on focused growth work across other Mechanism companies. That is part of what makes the role interesting. You will see more business models, more constraints, and more growth problems than you would inside one company, then bring those lessons back to HeySunday.
