pressw - Senior Engineer – Frontend / Mobile Lead
Requirements
• 7+ years of frontend engineering experience including a senior-level track record shipping production mobile applications. • Strong React and TypeScript. Production Expo/React Native experience required. • Demonstrated ability to ship the same product across web, iOS, and Android with a small team. • Comfortable working in Python. The first ~20 weeks involve auth infrastructure work before the frontend pivot. • Must have shipped meaningful code in the last 2 years. • Healthcare or scheduling/appointment UX experience. • Identity and access management experience (SSO, JWT, multi-tenant auth). • Design system and component library ownership. • Accessibility (WCAG) expertise. • AI-assisted development workflows (Claude Code, MCP, agent tooling).
Responsibilities
• Lead the identity and access migration (Phases 0-2): IAM platform deployment, dual-auth middleware, per-tenant auth cutover. This work is the first customer-facing deliverable of the engagement. • Partner with the Principal Engineer on frontend architecture. Own implementation of the web application (Vite + React 19) and mobile application (Expo/React Native) with a shared TypeScript service layer. • Ship the frontend in two batches: worker-facing first (schedule viewing, shift pickup, messaging, punch clock, push notifications), then admin-facing (template management, schedule building, reporting, compliance). The admin batch rebuilds the #1 churn driver. • Enable push notifications on the Expo mobile app. Push is currently disabled. This is a table-stakes feature for a workforce scheduling platform. • Build the component library and design system in collaboration with the UX Designer, who will have months of research completed before frontend development begins. • Instrument product analytics and session replay on every new frontend surface (platform selected during Phase 0B). • Set quality standards for accessibility (WCAG 2.1 AA target), performance, and design fidelity. • Mentor mid-level engineers; contribute to hiring.
Benefits
• You rebuild the entire user experience for a platform that hundreds of thousands of workers and 1,000+ facilities depend on daily. Two apps, two audiences, one shared foundation. Small team, high autonomy, real stakes.
