Frontend Engineer, Platform

Grow Therapy is building a dedicated Frontend Platform team. The role involves owning the design system and web foundation, improving performance and accessibility, and developing tooling for product teams. This is a foundational role on a new team with real room to shape web engineering.

• 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

• 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
• Bring enough product sensibility to build a platform people actually want to use — you understand the product surface your work powers
• 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
• 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
• Bring a founder's mindset: ownership, speed, pragmatism, and bias toward action
• Bonus: Experience with experimentation/feature-flagging, localization (i18n), or accessibility tooling at a systems level
• Bonus: Monorepo or frontend build tooling experience (Turborepo, Nx, Vite)
• Bonus: Product engineer background before moving toward platform

• Comprehensive Health Coverage: Medical, dental, and vision insurance, plus life and disability coverage.
• Parental Leave & Family Support: Up to 18 weeks paid leave and a new child stipend.
• Financial Wellness: 401(k) program and equity opportunities.
• Meals & Home Office Support: Stipends for home office setup and ongoing funds for meals, with tailored perks for both remote and in-office employees.
• 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, and memberships to leading wellness apps (such as One Medical, Headspace, and Talkspace).
• Extra Perks: Pet insurance discounts, commuter benefits, and global travel assistance.
