Entry level junior web developer Offres d'emploi - Mississauga, ON

About Myant: Myant is building the technologies that connect people, machines and intelligence through advanced textile computing, materials science, AI and connected health technologies.

Within the Myant ecosystem, Myant Health is focused on transforming healthcare through the Internet of Humans: connecting people, AI and machines through intelligent textile-based interfaces and continuous health measurement.

Our SKIIN™ technology transforms everyday clothing into a sophisticated health interface capable of capturing meaningful, clinical-grade health information, while HumanOS provides the platform for bringing together data from textile sensors, medical devices, wearables and other connected technologies to create a more continuous view of human health.

Myant Health is currently focused on objective measurement and accessible diagnostic solutions across areas including cardiovascular health, sleep, hypertension, diabetes and musculoskeletal health.

Our work includes solutions such as 14-day cardiac monitoring, home sleep apnea testing and ambulatory blood pressure monitoring, with a broader vision of creating continuous diagnostic and, ultimately, therapeutic interfaces that can become part of everyday life.

The technology and innovation behind these products are supported by a broader Myant R&D environment spanning textile computing, advanced materials, electronics, software, AI, biometrics, chemical processing and manufacturing technologies.

This includes MyantX, our advanced research and innovation organization, which builds on a strong history of industrial research and applied technology development.

MyantX operates at the intersection of materials, manufacturing, electronics, sensing and emerging technologies, helping translate advanced research into practical technologies and commercial applications.

Together, Myant, Myant Health and MyantX operate within a highly multidisciplinary environment that brings together research laboratories, advanced materials and chemical processing, engineering, textile and electronics development, controlled manufacturing environments and medical-device development and manufacturing.

This creates a unique environment for professionals who want to work at the intersection of advanced technology, research, manufacturing, quality, safety and regulated healthcare.

At Myant, you will have the opportunity to work alongside scientists, engineers, researchers, manufacturing specialists, healthcare professionals and technology teams to help build technologies that move from fundamental research and experimentation through development and ultimately toward real-world applications.
