Frontend Architect @ Linus Health

Software Engineering (1)

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 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
