About TRX Training
TRX Training is the creator of the original Suspension Trainer and a integral leader in functional fitness, providing equipment, training programs, and the TRX App — a subscription platform delivering 2,000+ workouts, live classes, and on‐demand content to consumers, coaches, and commercial partners worldwide.
TRX is investing in mobile as a core part of its growth strategy, with iOS as the primary platform for new value and differentiation going forward.
About the Role
We are looking for a Senior iOS Engineer to join the TRX product team on a full‐time, dedicated basis. This role focuses on owning the iOS platform end‐to‐end architecture, hands‐on delivery, and backend collaboration.
The ideal candidate is a strong independent contributor who thinks beyond the codebase: comfortable making architecture calls, shipping PRs with minimal oversight, working closely with backend teams, and weighing technical decisions against business and product priorities.
Key Responsibilities
Platform Ownership & Architecture




- Own iOS architecture and technical direction as the app becomes the primary mobile investment
- Design and evolve a modular, scalable codebase (MVVM/MVVM‐C or Clean Architecture)

Delivery & Execution
- Design, build, and ship features independently — write, review, and merge PRs with minimal oversight
- Set up and maintain CI/CD, release, and App Store submission processes

Backend Collaboration
- Work closely with backend/API teams on subscriptions, content delivery, and streaming
- Contribute directly to backend logic or API contracts when needed

Product & Business Judgment
- Weigh trade‐offs between speed, quality, and cost in line with TRX's commercial goals
- Influence scope and prioritization decisions, not just implementation

Cross‐functional Collaboration
- Collaborate with design, product, and QA in an agile (Scrum/Kanban) environment
- Mentor and set technical standards as the senior‐most iOS voice on the team
