Solve Complex State Problems: Clinical processes have real constraints — availability, resources, treatment stages, market-specific rules. A lot of the difficulty here is modelling state correctly, not styling it.
Bridge Frontend & Backend: Collaborate closely with backend engineers on API contracts and end-to-end flows that cross several services.
Raise the Bar on Quality: Solution and architecture reviews before implementation starts, unit and e2e coverage on critical paths, monitoring and error tracking after release.
Use AI as Part of Your Workflow: AI assistants are part of our everyday workflow — in implementation, review and testing. You will use them daily and help improve the workflows around them.
Requirements:
~5+ years of frontend development experience.
~ Expert-level React — you understand the internals, not just the API.
