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

What We’re Looking For
Experience

8+ years of professional iOS development experience, including recent senior/lead‑level ownership of a production app

Proven experience shipping consumer apps end‑to‑end, ideally subscription, streaming, or media‑delivery products

Experience working across iOS and, ideally, some exposure to Android/Flutter (useful for informed platform‑strategy conversations, not hands‑on Android work)

iOS & Technical Skills

Deep Swift expertise; strong grasp of MVVM / MVVM‑C or Clean Architecture and modularization

Working knowledge of backend concepts (REST/GraphQL APIs, data modeling, auth flows)

Experience with CI/CD for mobile (Fastlane or equivalent), SPM/CocoaPods, and app store release processes

Ability to work autonomously and deliver end‑to‑end with little supervision

Collaboration & Communication

Strong communication skills and ability to advocate for technical and product trade‑offs

Comfortable explaining architecture decisions to non‑technical stakeholders

Ability to collaborate effectively with product, backend, and design teams

Technical Profile Requirements
Candidates should be ready to speak to:

A production iOS app they owned or led architecturally, with concrete examples of decisions made

Examples of PRs or features shipped independently, end‑to‑end

Experience integrating with or influencing backend/API design

Their approach to CI/CD and release process ownership

Personality & Mindset
We are looking for someone who:

Has a sense of humor and no ego

Holds strong technical opinions, loosely held

Enjoys owning a platform end‑to‑end rather than just executing tickets

Thrives in a fast‑moving, mostly autonomous environment

Is comfortable weighing business trade‑offs alongside technical ones

Communicates clearly and can challenge ideas constructively

Languages
English: C1 level or above required for daily collaboration.
