Sr. iOS Full-Stack Developer

About TRX Training

TRX Training is the creator of the original Suspension Trainer and a global 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.
