Company Description

We’re TSG. There’s a good chance you’ve not heard of us yet – we’re just getting going. We’re the people who power gyms, fitness facilities, childcare centers and independent personal trainers in a load of places across the globe (US, Aus, NZ, UK, Japan, France, and Canada, with more to come). We’re bringing together the very best companies in the industry through smart, intentional acquisition. And we’re getting ready to go big. 

In the US, we’ve brought together Mariana Tek, Zingfit, Triib and TrueCoach, to form our Boutique Vertical. There’s over 140 of us in the Boutique team and we’re passionate about fitness, stellar customer support and creating tech that solves problems for busy people. We’re based across the US with offices in DC, Boulder, Louisville and Boston. Our products are already revolutionizing boutique fitness, by automating admin and other tasks for gym owners and trainers, so they can get out of the office and spend more time doing what they love. 

If you’re passionate about tech, fitness and working with talented, ambitious people, then we’d love to hear from you

Job Description

Our Rails JSON API, currently serving 4 different frontend clients, serves as the heart of the TrueCoach platform. We have scaled up rapidly this year, with usage growth of over 70% since February, and while we’ve handled that growth relatively well, interesting scaling challenges lie ahead. As a Staff Engineer on the Backend Team you will be responsible for maintaining and extending this core API, its associated admin panel as well as several satellite services (Rails + AWS), and our Heroku based infrastructure.

In this position, you'll be responsible for overseeing, extending and maintaining the backend services that power the core of the platform, as well as leading the backend team to success by working to coordinate team alignment, facilitating guild meetings and providing expertise as needed. You’ll oversee architecture decisions, mentor other engineers and work alongside product and design to help us ensure we build the right thing in the right way at the right time. We have a solid foundation, with revenue and happy customers that love us, but we're just getting started.
