F45 Training Inc., headquartered in Austin, Texas, offers consumers functional 45-minute workouts that are effective, fun, and community-driven. F45 utilizes proprietary technologies: a fitness programming algorithm and a patented technology-enabled delivery platform that leverages a rich content database of over 4,000 unique functional training movements to offer new workouts each day and provide a standardized experience across the Company's global footprint in over 65 countries.

In this key role, you’ll be responsible for the development of F45’s proprietary heart rate monitoring and wearable technology, LionHeart. The LionHeart system tracks participant heart rate zones through a wireless heart rate monitor and displays the results in realtime on the studio leaderboard. At the end of every class, the LionHeart system compiles a participant's workout session into a summary graph that can then be viewed within the F45 iOS/Android App.

LionHeart has been highlighted as one of F45’s fastest growing technologies and offers extensive gamification opportunities. As the Lead LionHeart Engineer, you will be responsible for completing the migration of the LionHeart backend system into AWS (the migration is nearly done but requires testing and configuration updates) and supporting the platform’s evolution. Additionally, you will work closely with the Product Team to develop new features that will engage and motivate members to achieve their fitness goals.

This is a software engineering role that requires in-depth knowledge of PHP and backend technologies. You will be responsible for keeping the service running and updating the application to use the latest PHP and framework version. While the position works very closely with hardware (heart rate monitor and in-studio Hubs), you will not be directly responsible for hardware related issues or building firmware; this position is entirely focused on backend API development and ancillary technologies (sending emails via API, computing data analytics, querying data from a database, updating a simple frontend website, etc.).

This role will regularly engage with stakeholders throughout the development cycle. As such, the ideal candidate must have excellent communication skills and understanding of agile practices.

The ideal candidate is a self-starter who is not only a talented engineer but is also willing to lean in and support the company in other cross-disciplinary areas including analytics and data reconciliation.

This role is a perfect opportunity for those who are interested in leveraging their software engineering skills to support the company’s digital evolution in the fitness industry.

Location: Remote (or hybrid). Candidates either from Austin, Texas or willing to work in US central time alignment (regardless of base location in US) are encouraged to apply.

Tech Stack: PHP/laravel, MongoDB, RDS (MySQL), redis, and NodeJS.
