Job description

About us

Icon Health is a navigation and care delivery company for all things musculoskeletal (MSK). Fifty percent of U.S. adults have a MSK disorder: from sprains and strains to back and neck pain. Icon aims to connect these patients to the best care possible, whether that's in-person or digital physical therapy, conservative treatments, surgical procedures, or anything in between.


We believe that the current healthcare system is broken. Patients must become informed consumers of healthcare, and we want to help them get there. With your help, we'll use the unprecedented availability of data on providers, increasing interoperability of diagnosis and treatment information, and widespread technology that allows scale beyond regionalized medicine to usher in a new era.

As one of the first Full Stack Engineers at Icon, youโ€™ll be a driving force behind crafting our product platform. The ideal candidate is someone who's passionate about understanding the context for features built to drive better patient experience and adoption and can flex from the front-end to the back-end. 


In this role you will collaborate with Iconโ€™s Product, Clinical, Sales, and Leadership teams to create high-impact user interfaces and robust and scalable services across product lines and functions. We are a small, fast-growing company, and we learn from each other every day. You'll be an integral part of our team.

  • Work collaboratively with people with different technical backgrounds, focus areas, and expertise.

  • Design systems with the objective of meeting user needs and business goals.

  • Have an Operational Mindset, and keep a constant perspective on improving the performance and maintainability of our platform.

  • Write understandable, high-quality code and deeply grasp the series of technologies that power products and applications.

  • Implement best practices that produce maintainable code, including usability patterns, code style conformity, and integration patterns. 

  • Analyze, design and develop test cases and implement automated test suites.

  • Strong analytical problem-solving skills.

  • Ability to work independently and be a self-starter in a dynamic, fast-paced environment.

  • Ability to develop robust and scalable services in Go, Java, Python.

  • Experience with one or several front-end JavaScript frameworks  like React, Node, Angular

  • Experience in implementing end-to-end cloud native services on one or more major cloud platform infrastructure provider - Google Cloud or AWS.

  • Knowledge of secure web development practices with troubleshooting complex application workflows and performance tuning.

  • Strong knowledge in writing Automated Test Suites using frameworks like Mocha, Cypress, Jest, or Selenium.

  • Ability to quickly learn new technologies and successfully implement them. 

  • Experience translating user experience design (mockups, wireframes and user journeys) into code.

  • Willingness and ability to engage with teams and collectively solve complex problems.

  • Comfort with ambiguity and rapid changes common in early-stage product development.

  • Strong project management and communication skills.

  • ~5 years total development experience.
