[solidcore] is seeking an experienced Senior Software Engineer to lead the design and architecture of our digital fitness platform. The ideal candidate will partner closely with product, engineering, and business stakeholders to drive technical decisions across our mobile and web applications, while building scalable backend services that support a seamless member experience. This role will also play a key part in mentoring engineers, elevating development practices, and exploring how AI-powered tools and automation can accelerate innovation across the organization.

Located in vibrant Arlington, Virginia, and reporting to the Director of Engineering, this is an exciting opportunity to join a rapidly growing, investor-backed organization with a passion for technical excellence and a mission to be the leader in the studio fitness space.
[solidcore] is a national boutique fitness company with 100+ studios across the country. Our signature workout is 50 minutes of low-impact, high-intensity strength training: the lights are low and the music is loud. The coach guides the class through a series of slow & controlled movements that are sequenced to work muscles to failure. This class is accessible for all fitness levels and can be amplified or modified to accommodate individual goals. Class is as intense as our reviews suggest, but our instructors go above and beyond to provide a welcoming, supportive, empowering, and challenging experience for all.
