Role Description We’re looking for a Staff Engineer - User Experience (Backend) to join our Patient Platform team and shape the systems that power patient-facing experiences across our health technology platform. This team owns the APIs, orchestration services, and communication infrastructure that enable secure, reliable interactions between patients and our platform (Email, SMS, notifications). We are at a critical stage of growth, scaling our platform, modernizing legacy services, and strengthening our event-driven architecture to support increasing patient volume and communication complexity. This role will play a central part in defining how our backend systems evolve as we scale. As a Staff Engineer - User Experience (Backend) , you will be the technical authority for the Patient Platform domain, translating architectural strategy into scalable, production-ready distributed systems in partnership with cross-functional teams. You will: - Drive the evolution of our API-first architecture (including BFF and orchestration patterns). - Define and enforce API contracts. - Modernize tightly coupled services into scalable, event-driven components. This is an opportunity for a senior technical leader who thrives in ambiguity, moves pragmatically, and enjoys balancing hands-on engineering with architectural influence. You will: - Strengthen reliability, observability, and fault tolerance across distributed systems. - Scale and harden our patient communication platform (Email, SMS, notifications). - Design secure systems handling sensitive patient and identity data in regulated environments. - Champion best practices in automated testing, CI/CD, and secure development. - Elevate engineering standards through mentorship, design reviews, and technical leadership.
