Our award-winning whole body scan is fast (under 1 hour), safe (MRI has no ionizing radiation), and non-invasive (no contrast). Our unique integrated stack of optimized hardware, software, and increasingly AI, coupled with the patient-centric experience across our domestic and global clinics, have allowed us to lead the change against “we caught it too late again\".\nWe're looking for a Senior Frontend Engineer I to join our eCommerce team, building the online booking experience patients use to choose a scan, find a clinic, pay, and schedule their appointment. You'll lead complex features in a Next.js and TypeScript application that serves customers in multiple countries, on flows where every screen directly affects conversion, revenue, and patient trust: product selection, checkout and payments, appointment scheduling across timezones, and our sales-assisted and partner booking paths. This is a high-impact role for someone who cares about the craft of the UI and about whether it actually works in production for every customer. If you enjoy solving ambiguous problems and owning outcomes rather than tickets, we'd love to hear from you.\nThis role does not provide visa sponsorship. Applicants must be legally authorized to work in the United States at the time of hire and must not require employer sponsorship for a work visa (current or future). \nHelp reshape the world through proactive healthcare while working with cutting-edge technology and high performing teams with deep expertise - join us to make a difference in people’s lives!\nWhat You’ll Do\nOwn features and components within an area of the booking experience, such as checkout and payments, scheduling, or the sales-assisted and partner flows, growing toward owning the area end to end.\nWork with Product and Marketing on growth: ship experiments on the booking funnel, then read the results honestly, including sample size, guardrail metrics, and whether a change is a real win or just noise.\nBuild fast, accessible, customer-facing features with React, Next.js (App Router), and TypeScript.\nContribute to frontend architecture and design, writing proposals you review with senior engineers: sensible server and client component boundaries, server state with TanStack Query, client state with Zustand, and type-safe forms with React Hook Form and Zod.\nIntegrate the booking experience with our commerce APIs and third-party services, including Stripe, Affirm, commercetools, Voucherify, Salesforce, Auth0, and Google Maps.\nInstrument what you ship: Datadog RUM for errors and performance, PostHog for product analytics, feature flags, and experiments, and Google Tag Manager for marketing measurement, all respecting each customer's consent choices.\nImprove Core Web Vitals, bundle size, and rendering performance on a high-traffic, revenue-critical funnel.\nMake accessibility a default: semantic markup, keyboard and screen reader support, and automated accessibility checks in CI.\nWrite automated tests at the right level: Vitest and Testing Library for components, MSW for API mocking, and Playwright for end-to-end booking flows.\nOwn outcomes in production: ship behind feature flags, watch the dashboards after release, and follow through when something breaks. You are accountable for whether a feature works for customers, not just whether it merged.\nPartner closely with Product, Design, Marketing, and Backend engineers, contributing to our shared component library and agreeing the API contracts the frontend depends on.\nProvide technical guidance through design discussions and high-quality code review, and mentor junior engineers.\nUse AI-assisted development tools thoughtfully as part of a structured build, review, and test workflow.\nWhat You’ll Bring\nTypically 4+ years of professional frontend engineering experience, including at least 3 years building production applications with React and TypeScript.\nStrong experience with Next.js or a comparable React framework, including server-side rendering, routing, and the tradeoffs between server and client rendering.\nDeep understanding of browser fundamentals: semantic HTML, modern CSS and responsive layout, the event loop, network and caching behavior, and the rendering pipeline.\nExperience with modern data-fetching and state management patterns (TanStack Query, Zustand, Redux, or similar) and with complex, validated, multi-step forms.\nStrong testing practices across unit, component, and end-to-end layers, using tools such as Vitest or Jest, Testing Library, and Playwright or Cypress.\nExperience building checkout, payment, or other transactional flows where correctness and reliability matter.\nWorking knowledge of web accessibility (WCAG 2.1 AA) and web performance (Core Web Vitals).\nExperience with frontend observability and product analytics tools such as Datadog RUM, Sentry, PostHog, or Google Analytics.\nHands-on experience with modern CI/CD practices and cloud hosting (for example GitHub Actions and AWS).\nA track record of leading complex features from design through production.\nA startup mindset: comfortable taking on ambiguous work, knowing when to pull in a second opinion on an approach, and able to balance speed with quality.\nExcellent communication skills and the ability to collaborate across engineering, design, and business teams.\nNice to Have\nExperience with Stripe.js and payment method integrations, including buy now, pay later providers such as Affirm.\nExperience with headless commerce platforms such as commercetools, or promotion engines such as Voucherify.\nExperience with Tailwind CSS and building on top of a design system or component library.\nExperience with consent management platforms (such as OneTrust), Google Tag Manager, and privacy-aware analytics.\nExperience with multi-region products: multiple currencies and locales, and correct date, time, and timezone handling.\nGrowth engineering experience: working on a team that owns acquisition, activation, or conversion metrics, and shipping many small experiments quickly.\nExperience with funnel analytics and marketing attribution: event tracking plans, UTM and referral attribution, and conversion tracking into ad platforms such as Google Ads and Meta.\nExperience building growth surfaces such as landing pages, email capture, referral programs, promo codes, and abandoned-cart recovery.\nExperience with authentication and identity providers such as Auth0.\nExperience with scheduling, booking, or consumer healthcare applications, or working in highly regulated industries.\nOur Values\nFirst: we are Pioneers\nTransforming healthcare requires divergent thinking, bias for action, disciplined experimentation, and consistent grit and determination to maintain momentum. This journey is as challenging as it is rewarding.\nSecond: we are Platform-Builders\nWe’re always building foundations that allow us to achieve tomorrow more than we did today. We never lose sight of what’s ahead - in a mindset of ownership and duty to our mission.\nAbove all: we are Patients\nWe could all be the next person who walks through our very doors, seeking clarity or peace of mind. We are proud of our impact on our patients’ lives, and we won’t stop till everyone can benefit from our work.\nWhat We Offer\nAn avenue to make a positive impact on people's lives and their health\nWe believe in preventative healthcare for everyone, including our team - Prenuvo provides free, whole-body scans to each team member \nGrowth opportunities are at the heart of our people journey, we’re doing big things with bright minds - there is no single path to success, it can be shaped along the way\nBuilding strong relationships is at the core of everything we do - our team gets together each week to connect, share, and socialize \nRecognizing time away to restore is vital to our wellbeing - we have a flexible vacation policy and we will encourage you to use it\nWe now offer the Prenuvo’s Commuter Benefits Plan to help cover your transit and parking costs.
