Principal Frontend Platform Engineer

About Medical Guardian

Medical Guardian is transforming from a device-centric emergency response company into a connected healthcare platform that empowers older adults and caregivers with greater independence, safety, and proactive wellness support.

As part of our multi-year Digital Transformation Initiative, we are modernizing and unifying our digital ecosystem, including member portals, caregiver experiences, senior living applications, and partner platforms, into a scalable, modular Unified App Platform.

We are seeking a Principal Frontend Platform Engineer to lead the frontend architecture, engineering standards, and platform strategy powering this transformation across web and mobile experiences.

As the Principal Frontend Platform Engineer, you will serve as the technical leader responsible for architecting and delivering modern, scalable, secure, and highly performant frontend applications across the Medical Guardian ecosystem.

You will drive the evolution of our Frontend Platform strategy using React, Next.js, React Native, Sanity.io, and modern cloud-native development practices. This role will establish frontend architectural standards, design system governance, authentication patterns, observability, and developer experience practices across engineering teams.

This is a highly strategic, hands‑on leadership role focused on enabling a modular, multilingual, multi‑brand digital platform supporting members, caregivers, partners, and internal operations. This role is expected to remain technically hands‑on, contributing to architecture, proof‑of‑concepts, critical implementation efforts, and frontend platform engineering initiatives.

You will work closely with Product, UX, Platform Engineering, AI/ML, Security, and backend services teams to deliver seamless digital healthcare experiences at scale.

• Serve as the principal technical authority and mentor for frontend engineers across multiple engineering pods.
• Establish and enforce coding standards, architectural governance, testing practices, and secure development patterns.
• Own the frontend platform technical roadmap, including architectural direction, modernization initiatives, technical debt reduction, and presentation of strategy and progress to engineering leadership.
• Improve frontend developer experience through tooling, local development workflows, CI/CD automation, automated testing, engineering documentation, and release enablement practices.
• Partner with platform and security teams to mature CI/CD pipelines, secure development workflows, automated quality gates, and frontend release processes.
• Establish scalable frontend release strategies including feature flags, staged deployments, rollback mechanisms, and production validation practices.
