Growth Mindset
We are doers, thinkers, and dreamers. At ABC Fitness, your growth is our investment. Through continuous learning, mentorship, and professional development opportunities, we empower you to reach new heights—personally and professionally.
One Team
From day one, you’ll be part of a team that collaborates, celebrates, and cares. We move fast, support one another, and have fun along the way. Because when you thrive, we all thrive.
You’ll join CRM Ops, the engineering squad that owns CRM operations and segmentation on the ABC Glofox platform — including tags, audiences, tasks, and Member Aggregate, our segmentation engine.

As we enhance our segmentation capabilities to support more use cases, you'll need to be an expert at optimizing and developing complex MySQL queries for a system that serves ~130M active members and all their CRM needs (workflows, marketing campaigns, reporting and more). You’ll help set backend technical direction for XLerate, providing technical guidance to a small team of 2–3 engineers, and partner closely with Product.
You’ll also work closely with partner squads such as Connect, which powers automations and communications alongside CRM, to continue building XLerate, our next-generation CRM product and a major priority for ABC Fitness.
