What project we have for you

Our client is a global leader in innovative health solutions, focused on traditional pharmaceutical production as well as digital healthcare products.

The objective of the project is to build modern web portals and web platform assets leveraging best-practices for modular cloud-optimized web architecture (stack: Javascript React (Next.js), Python and GCP).

What you will do

  • Build responsive, component-driven UIs with Next.js/React and TypeScript (SSR/SSG/ISR) for speed, SEO, and reliability.
  • Implement global design systems (tokens, components) using Tailwind CSS or CSS Modules and Storybook.
  • Integrate headless CMS content (e.g., Contentful, Sanity, Adobe AEM headless) and external services via REST/GraphQL.
  • Ensure accessibility (WCAG 2.1+ AA), cross-browser parity, and performance budgets (LCP, CLS, INP).
  • Collaborate in agile ceremonies; break down epics into tickets, estimate work, and deliver iteratively.
  • Partner with Compliance/MLR to implement content guardrails (disclaimers, PI/ISI placement, cookie consent).

What you need for this

  • 4+ years of front-end experience, including 2+ years with Next.js in production.
  • Strong TypeScript, React hooks, component composition, and state management experience.
  • Demonstrated SSR/SSG/ISR implementation, routing, data-fetching patterns, and image optimization in Next.js.
  • Proven accessibility and responsive design skills; familiarity with semantic HTML and ARIA.
  • Testing discipline (unit/integration/e2e) and CI familiarity.
  • Experience integrating with headless CMS and designing consumable front-end APIs.
  • Performance and SEO know-how (meta tags, structured data, sitemaps, robots, caching/CDN).
  • Excellent collaboration and communication with design, content, QA, and non-technical stakeholders.

Nice to Have

  • Experience in regulated industries (pharma, medical device, healthcare) and MLR review workflows.
  • Design systems at scale (Storybook, Chromatic, tokens).
  • Analytics/experimentation (GA4, Adobe Analytics, Launch, Optimizely).
  • Security and privacy basics (consent management, CSP, OWASP).
  • Familiarity with Vercel platform features and Edge functions.
  • Experience with internationalization frameworks (next-intl, next-i18next).
  • Exposure to Azure/AWS services and infrastructure-as-code basics.
