## Description

This is a senior, hands-on engineering role at the heart of our product. You'll lead full-stack development across our mobile apps, React web platform, and AWS backend services. You'll own the architectural decisions that shape how Movetru scales. We're a small team, so the scope is wide and your role is a core component to the company.

You'll be a sounding board on technical strategy, an embedded contributor in day-to-day delivery, and a foundation for the engineering team we build around you.

What You'll Do

 * Build and maintain Movetru's mobile applications for iOS and Android
 * Architect and implement service-based systems spanning our AWS backend and React front end
 * Build and maintain Movetru's modern web platform in React JS
 * Design and manage our backend services, APIs, and AWS infrastructure
 * Design, integrate, and optimise AI agent workflows, and embed AI-driven features into our products and services
 * Use LLMs and AI agents to accelerate everyday development
 * Own code quality - write clean, scalable, maintainable code and raise the bar across the codebase
 * Build and maintain automated tests and monitoring to keep our applications and services reliable.
 * Debug, profile, and optimise complex performance issues across platforms
 * Apply secure development practices and appropriate controls for handling data.
 * Collaborate closely with designers, sports scientists, and product to turn research into shipped features
 * Mentor and shape the engineering practice as the team grows
