About the role

  • Our award-winning whole body scan is fast (under 1 hour), safe (MRI has no ionizing radiation), and non-invasive (no contrast).
  • This role does not provide visa sponsorship.

Responsibilities

  • Optimize the User Experience: Identify and eliminate friction points in the booking funnel, optimize page load performance, and ensure WCAG accessibility compliance across all flows.
  • Drive Experimentation & Growth: Design, implement, and analyze A/B tests using a platform like PostHog or DataDog. Build feature flag infrastructure for gradual rollouts and track conversion metrics at each stage of the funnel.
  • Own Frontend Architecture: Build highly responsive interfaces using a hook-first architecture (separating business logic from presentational components) and modern state patterns (optimistic updates, single-flight request patterns).
  • Ensure Reliability & Observability: Set up and maintain Datadog RUM dashboards, implement comprehensive error tracking, and debug production issues to maintain high system reliability.
  • Implement Secure Integrations: Build secure authentication flows (Auth0, OAuth 2.0) and handle payment processing data (Stripe, Affirm) according to strict PCI and frontend security standards.
  • Collaborate & Mentor: Work autonomously while surfacing blockers early. Mentor junior engineers, partner closely with Product and Design, and comfortably challenge product decisions using data.

Requirements

  • A strong "startup mentality": you are comfortable with ambiguity, know how to balance speed with quality, and take deep ownership of outcomes.
  • Excellent communication skills, with the ability to explain complex technical concepts to non-technical stakeholders.
  • Solid experience with modern state management (Zustand, TanStack Query) and utility-first CSS (Tailwind).
  • Hands-on experience with monitoring and experimentation tooling (Datadog RUM, PostHog, or similar).

Nice to have

  • Experience with e-commerce, checkout flows, or headless commerce platforms (e.g., CommerceTools).
  • Experience with design systems and mobile-first design implementation.
  • Experience with component libraries (e.g., Material UI) and implementing mobile-first design systems.
  • Deep performance optimization expertise (Core Web Vitals, bundle optimization).
  • Knowledge of Google Tag Manager (GTM) and Google Analytics 4 (GA4).
  • Experience with Next.js (App Router, SSR/SSG patterns).
  • This journey is as challenging as it is rewarding.
  • We could all be the next person who walks through our very doors, seeking clarity or peace of mind.
