for testing, observability, CI/CD, and deployment practices. Partner with product and leadership
to translate complex problems into clean, scalable solutions. Guide technical strategy and roadmap
decisions to ensure we’re building with scalability, security, and simplicity in mind. Collaborate cross-functionally
with mobile, design, and clinical stakeholders to deliver reliable and delightful user experiences. What We’re Looking For
