• Strong testing and debugging skills; experience writing unit, integration, and end-to-end tests

• Technical leadership, creative problem solving, and high-quality communication skills

• You’ve done it before, at scale – you have some hard-won lessons from the industry, and bring a deep understanding of navigating a technology team through the start-up scale up phase of growth

• You’re passionate about improving the Canadian healthcare experience and have a personal connection to the space
