Senior Full-Stack Engineer

Project Overview
We're building a platform that helps test for viral diseases — from clinics to people's homes. The product brings together hardware devices, firmware, a mobile app, and a cloud/admin backend, all working in sync. Because we operate in the healthcare space, the platform is HIPAA-compliant and built with data security as a top priority.
We're looking for a Full Stack Developer to help us build and scale features across our mobile app, cloud services, and APIs. You'll work closely with firmware and QA teams to ship a product that's actually used in real diagnostic workflows.
