FrontEnd Architect (React)

Remote, United States

Linus Health is a Boston-based digital health company transforming brain health worldwide. We combine cutting-edge neuroscience, clinical expertise, and AI to advance early detection and intervention for cognitive and brain disorders—empowering people to live longer, healthier lives. With 100+ team members and growing, we’re entering a phase of accelerated growth and looking for top talent to help shape our future.

The Role:

We’re looking for a Frontend Architect to define and evolve the technical vision for Linus Health’s web applications. You’ll lead the design of scalable, performant, and accessible React-based systems, shape our component libraries and design systems, and ensure that engineering excellence scales across teams. You’ll also champion AI-assisted development practices, both to accelerate engineering workflows and to bring clarity through advanced visualization in the UI. While this role is primarily focused on the web, experience with mobile (React Native or Swift) is a strong plus, as many of our products span both platforms.

What You’ll Do:

  • Set the frontend architecture direction for React-based apps—performance, modularity, security, and long-term scalability
  • Lead a Team to re-imagine our web applications into a cohesive, flexible and performant application that is easy to develop in
  • Design and maintain a reusable component library/design system, ensuring consistency, accessibility (WCAG compliance), and internationalization across apps
  • Integrate AI-assisted visualization into user experiences, enabling clinicians and patients to understand and interact with complex health insights
  • Establish best practices for testing (unit, integration, snapshot, e2e), CI/CD pipelines, code quality, and observability in frontend systems
  • Mentor and empower engineers across multiple teams, raising the bar through reviews, workshops, and shared documentation
  • Collaborate cross-functionally with Product, Design, Data Science/Medical, and Security to translate requirements into elegant, maintainable solutions
  • Promote responsible AI-assisted coding practices, ensuring speed gains are paired with validation, security, and reliability
  • Drive frontend innovation, such as SSR/ISR strategies, advanced state management, and performance profiling

What You’ll Bring:

About You:

  • 10+ years of software engineering experience with significant expertise in frontend architecture
  • 5+ years building large-scale applications in React, including deep understanding of hooks, context, state management, and performance tuning
  • Strong grasp of modern JavaScript/TypeScript tooling and ecosystems (Webpack, Vite, Babel, ESLint, Jest, Cypress/Playwright)
  • Experience leading design system or component library initiatives at scale (Storybook, theming, accessibility, documentation)
  • Familiarity with AI-assisted development workflows, and proven ability to integrate AI-powered visualizations into user-facing apps
  • Proficiency in frontend performance optimization (bundle splitting, lazy loading, caching strategies, rendering patterns)
  • Effective communication skills—able to drive consensus, document decisions (ADRs, RFCs), and present tradeoffs clearly to technical and non-technical stakeholders

Nice To Have’s:

  • Experience with mobile development in React Native or iOS/Swift
  • Exposure to data visualization libraries (D3, Victory, Recharts, or native iOS charting)
  • Previous work in digital health or regulated environments (HIPAA, GDPR)
  • Familiarity with backend-for-frontend (BFF) patterns
  • Contributions to open-source projects or design systems

How You Embody Our Values:

At Linus, we live by Be Real, Be Wise, Be Noble, Be a Team, Be Masters of Our Craft, Think Big and Act Bold. In this role, you will:

  • Be Real: Communicate architectural tradeoffs and risks candidly across teams
  • Be Wise: Guide design choices using data, metrics, and long-term thinking
  • Be Noble: Uphold privacy, accessibility, and inclusivity in every frontend decision
  • Be a Team: Enable engineers to succeed through mentorship, documentation, and open collaboration
  • Be Masters of Our Craft: Set exemplary standards for frontend quality, performance, and maintainability (including AI-assisted workflows)
  • Think Big and Act Bold: Lead bold initiatives like shared design systems and cross-platform consistency that transform how we build products

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
