FRONTEND AI ENGINEER

Location: Hybrid | Type: Full-time

About Newpage Solutions

Newpage Solutions is a global digital health innovation company helping people live longer, healthier lives. We partner with life sciences organisations which include, pharmaceutical, biotech and healthcare leaders, to build transformative AI and data driven technologies addressing real-world health challenges.

From strategy and research to UX design and agile development, we deliver and validate impactful solutions using lean, human-centered practices.

We are proud to be a 'Great Place to Work ' certified company for the last three consecutive years. We also hold a top Glassdoor rating and are named among the "Top 50 Most Promising Healthcare Solution Providers" by CIOReview. As an organisation, we foster creativity, continuous learning and inclusivity, creating an environment where bold ideas thrive and make a measurable difference in people's lives.

Your Mission

We are hiring Front-End Engineers to build the surfaces where AI outputs meet real users: streaming chat, dense dashboards, multi-view visualizations, and the interaction patterns that make non-deterministic systems feel trustworthy.

You are not implementing fixed designs. You are co-shaping how people actually interact with what AI produces, across audiences with different mental models on the same product. You partner closely with product, design, and engineering to translate ambiguous ideas into interfaces that ship.

You treat AI as the substrate of how software gets built: not a tool to be cautious of, not something you are "exploring," but the medium you work in. You work fluently with Claude Code, Cursor, and modern AI-assisted development workflows.

What You'll Do Shape the Surface

• Sit with product, design, and engineering to translate evolving requirements and ambiguous ideas into shipping interfaces.
• Co-shape interaction patterns for AI-driven experiences (streaming responses, evidence citations, confidence cues, guided workflows) as UX is stress-tested with real users.
• Build prototypes fast to react to. Iterate from rough designs and feedback rather than waiting for finished specs.
• Distinguish AI-surfaced output from authoritative or human-approved content visually and structurally, because in enterprise contexts that distinction matters.

Build (Fast) with AI

• Build production-grade front-ends in React 18+ with TypeScript, using Next.js (App Router) or equivalent meta-frameworks (Remix, TanStack Start).
• Implement streaming UI patterns for chat interfaces and agent interactions: Server-Sent Events, streaming fetch, optimistic updates, partial rendering.
• Build dense, real-time dashboards with multi-level drill-down (portfolio segment entity task) and multi-view visualizations.
• Implement data visualizations using Recharts, Visx, D3.js, Plotly, or ECharts, including radar/spider charts, time-series, and custom chart compositions.
• Build component architectures grounded in design systems and tokens, using Tailwind CSS with shadcn/ui, Radix UI, Material UI, or Mantine.
• Implement client and server state cleanly: TanStack Query for server state; Zustand, Redux Toolkit, or Jotai for client state.
• Use AI-assisted development tools (Claude Code, Cursor, GitHub Copilot) through structured workflows, templates, and sub-agents, with discipline and review.

Ship, Operate, Harden

• Own role-based access at the UI layer, integrate with enterprise SSO (Okta, Auth0, Entra ID, or equivalent) using the appropriate SDK.
• Implement forms with React Hook Form + Zod (or equivalent schema validation) for type-safe data flow end-to-end.
• Write tests that hold up: Vitest or Jest, React Testing Library, Playwright for E2E.
• Build to WCAG 2.1 AA conformance: keyboard navigation, ARIA patterns, accessible colour and contrast, screen reader support.
• Deploy on AWS (or Cloudflare for edge use cases), chosen for fit.
• Apply engineering practices that hold up in production: structured logging, observability, performance budgets, automated CI/CD (GitHub Actions).
• Own what you build end-to-end, including how it behaves in production.

What You Bring

• 3+ years modern front-end engineering experience, production-grade.
• Bachelor's or Master's in Computer Science, Design Engineering, or a related discipline (or equivalent demonstrable experience).
• Strong React 18+ and TypeScript fundamentals, with hands-on Next.js (App Router) or equivalent meta-framework experience.
• Data visualization experience: radar/spider charts, multi-level drill-down dashboards, real-time data views. Hands-on with at least one of Recharts, Visx, D3.js, Plotly, or ECharts.
• Streaming UI experience: Server-Sent Events, streaming fetch, real-time data patterns, chat-style interfaces with progressive rendering.
• Component architecture and design-system implementation. Hands-on with Tailwind CSS and at least one component library (shadcn/ui, Radix UI, Material UI, or Mantine).
• Strong state management with TanStack Query plus one of Zustand, Redux Toolkit, or Jotai.
• Forms and validation: React Hook Form + Zod or equivalent.
• Testing discipline: Vitest or Jest, React Testing Library, Playwright (or equivalent) for E2E.
• WCAG 2.1 AA conformance, keyboard navigation, ARIA patterns.
• Active, structured use of AI-assisted development tools (Claude Code, Cursor, GitHub Copilot) with demonstrable workflows.
• Comfortable iterating from evolving designs and co-shaping interaction patterns rather than executing fixed specs.
• Strong attention to information hierarchy: you can hold multiple audiences with different mental models in your head on the same product.
• A real, recent trail of built things: GitHub, a portfolio, side projects, indie tools, or OSS contributions.
• A no-compromise attitude on clean code, performance, accessibility, and user experience.

Bonus Skills / Experience

• Experience building front-ends for LLM-powered products: streaming chat UIs, evidence citation surfaces, agent interaction patterns.
• Design tokens and design-system implementation experience at scale.
• Storybook for component documentation.
• Real-time data patterns: WebSockets, server-driven UI, optimistic updates.
• Authentication flows with enterprise SSO providers (Okta, Auth0, Entra ID, or equivalent).
• Healthcare or life sciences domain exposure.
• Public writing, talks, or threads about building with AI.
