Frontend Platform Engineer

About Us:

Grow Therapy is on a mission to serve as the trusted partner for therapists growing their practice, and patients accessing high-quality care. Powered by technology, we are a three-sided marketplace that empowers providers, augments insurance payors, and serves patients. Following the mass increase in depression and anxiety, the need for accessibility is more important than ever. To make our vision for mental healthcare a reality, we’re building a team of entrepreneurs and mission-driven go-getters. Since launching in February 2021, we’ve empowered more than ten thousand therapists and hundreds of thousands of clients across the country and insurance landscape. We’ve raised more than $178mm of funding from Sequoia Capital, Transformation Capital, TCV, SignalFire, and others.

The Opportunity:

We're looking for a Frontend Platform Engineer to build the platform that powers consumer-grade product experiences at scale. This role sits at the intersection of design, product, and engineering, focusing on the core systems, architecture, and tooling that enable teams to move faster with confidence.

You'll own the horizontal infrastructure that makes our web applications fast, reliable, accessible, and easy to develop on — from web architecture and performance to experimentation frameworks, design system infrastructure, localization, and developer experience. Your work will enable every product team to ship high-quality, consistent experiences without reinventing the foundation.

This is a foundational role on a new team. You'll shape how web engineering scales at Grow as we launch a major new brand with significant marketing investment behind the web experience you build.

What You'll Be Doing:

• Build and maintain our core design system, used by both engineers and designers — owning architecture, governance, and extensibility
• Own web application architecture, including SSR strategy, build tooling, dependency management, and CI/CD for frontend
• Drive performance and reliability across all web surfaces — Core Web Vitals, caching, frontend observability
• Develop scalable, reusable frontend components and frameworks that power consistent, high-quality experiences
• Establish and drive best practices across accessibility, performance, localization, and responsiveness
• Build experimentation infrastructure at the web layer so product teams can run A/B tests with confidence
• Improve UI consistency and reduce regressions through strong abstractions, testing, and tooling
• Partner with product and engineering teams to integrate platform capabilities into their workflows
• Help shape an AI-forward development approach — accelerating and democratizing frontend development
• Create clear documentation, guidelines, and governance to support adoption and extensibility

You'll Be a Good Fit If:

• 5+ years of frontend or full-stack engineering experience, ideally on platform, infrastructure, or developer experience teams
• Experience building and scaling design systems, component libraries, or developer platforms
• Fluent in modern frontend technologies (JavaScript/TypeScript, React, Next.js, CSS systems)
• Comfortable leveraging AI-assisted development workflows
• Strong understanding of web performance (Core Web Vitals, caching, bundle optimization) and frontend observability
• Experience with experimentation frameworks, feature flagging, or A/B testing infrastructure
• Collaborate effectively with designers and engineers across the product lifecycle
• Deep understanding of accessibility (WCAG) and localization at a systems level
• Think in systems — identifying patterns, simplifying complexity, and designing for reuse
• Communicate clearly and influence product and UI decisions
• Bring a founder's mindset: ownership, speed, pragmatism, and bias toward action

Bonus Points:

• You've built experimentation infrastructure or feature flagging systems from scratch
• You have experience with localization (i18n) frameworks or accessibility auditing tooling
• You've worked with monorepo tooling (Turborepo, Nx) or frontend build optimization
• You were once a product engineer before moving into platform — you understand both sides
• You use modern AI tools (e.g., Cursor, GitHub Copilot) to boost your productivity and focus on higher-leverage problems

Why This Role Is Exciting:

As we scale, maintaining a consistent, high-quality user experience becomes increasingly complex — and increasingly important. This role ensures we can move fast without sacrificing quality by building the foundation that every team relies on. You'll play a critical role in shaping our product's technical identity, strengthening the partnership between design and engineering, and delivering a consumer-grade experience that sets a new standard in healthcare.

Role Details:

• Hybrid Commitment: $182,000–$250,000 USD USD Annually

This role is hybrid, onsite from our NYC, San Francisco, or Seattle hub location.

The base compensation for this role will vary depending on several factors, including relevant experience, qualifications, and the candidate's working location.

• 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 (“Mental Health Mornings/Afternoons”) and memberships to leading wellness apps (such as One Medical, Headspace, and Talkspace).
