Job Analysis:

This Full Stack Developer role at Fitmate sits at the heart of scaling a highly impactful digital health product that combines human coaching with AI to improve users’ adherence to healthier lifestyles. The candidate is expected not just to write code but to lead the design, implementation, and deployment of complex backend services within a cloud-based, microservices architecture, emphasizing operational excellence and ownership.
