Frontend Engineer, Platform

About the role

We're building a dedicated Frontend Platform team at Grow Therapy. This role is for a Frontend Engineer who loves working on the systems that every product team builds on. You'll own the design system and the horizontal web foundation.

Responsibilities

• Own and evolve our design system — architecture, tokens, theming, governance, and the patterns product teams rely on, in close partnership with Design Engineering
• Build the horizontal web foundation: shared components, frameworks, and the architecture that product teams build features on top of
• Improve performance, accessibility, and consistency across all web surfaces — making quality the default rather than something each team re-solves
• Develop the tooling and developer experience that help product teams move quickly and confidently, including an AI-forward approach to frontend development
• Partner with product and engineering teams to bring platform capabilities into their workflows, and contribute improvements back from real product needs
• Create the documentation and guidance that make all of the above easy to adopt

Requirements

• 5+ years of frontend or full-stack engineering experience, with a track record of work that other engineering teams depended on
• Experience building or scaling design systems, component libraries, or shared frontend infrastructure — with an instinct for horizontal impact over one-team feature work
• Fluent in modern frontend technologies (JavaScript/TypeScript, React, Next.js, CSS systems)
• Think in systems — seeing patterns, simplifying complexity, and designing for reuse across teams
• A strong understanding of accessibility (WCAG) and web performance as shared, systemic concerns
• Comfortable with AI-assisted development (AI tools are part of our daily workflow and our interview loop)
• Communicate clearly and influence engineering and UI standards across teams
• Bonus points if you've worked with experimentation/feature-flagging, localization (i18n), or accessibility tooling at a systems level
• Bonus points if you have monorepo or frontend build tooling experience (Turborepo, Nx, Vite)
• Bonus points if you were a product engineer before moving toward platform — you understand both sides

Qualifications

• Experience with Next.js
• Experience with design systems and component libraries
• Experience with AI-assisted development
• Experience with accessibility and web performance

• Frontend development
• Design systems
• Component libraries
• AI-assisted development

• Time Off to Recharge: Flexible PTO, 12 paid holidays, and a full winter break week
• Wellness & Development: Annual stipends to put towards personal & professional growth
• Mental & Physical Health Support: No-cost access to therapy through the Grow platform, weekly flexible hours for self-care (“Mental Health Mornings/Afternoons”) and memberships to leading wellness apps (such as One Medical, Headspace, and Talkspace)
