[Hiring] Senior Frontend Engineer @Seed

Role Description

As a Senior Frontend Engineer, you lead the frontend implementation of Seed's digital experience. You have a deep love for product, a keen eye for design, and the technical depth to turn ambitious designs into fast, accessible, pixel-perfect features on our React/Next.js platform. You work inside a design system owned by a Staff peer and contribute production-ready components back to it. You partner early with Design and Product, own quality on your squad's surfaces, and raise the frontend bar for the engineers around you through code review, pairing, and mentoring.

What You'll Do

• Build and Ship
  • Lead the frontend implementation of new features, from Figma through production.
  • Translate designs into production-ready code with obsessive attention to spacing, typography, motion, and responsiveness.
  • Own the frontend architecture behind your features: state management, data fetching, rendering performance, and test coverage.
  • Build accessible, performant interfaces that hold up across browsers and devices.
  • Ship safely: feature flags, A/B tests, instrumentation, and clear rollback paths.
  • Partner early with Design and Product to assess feasibility and resolve ambiguity.
• Contribute to the Design System
  • Build composable, reusable React components into our shared library, following its architecture, APIs, and documentation standards.
  • Use design tokens and theming consistently so that a component built once is available everywhere.
  • Document what you add via usage guidelines, code examples, and Storybook stories.
• Raise the Bar
  • Conduct thoughtful code reviews that hold the squad to a high standard in component design, accessibility, and visual fidelity.
  • Mentor engineers on the team through pairing.
  • Champion consistent use of the shared component library across our web applications.

Qualifications

• 6+ years of professional experience in frontend engineering.
• A strong portfolio or GitHub that shows your frontend work and your eye for UI craft.
• A track record of shipping production frontend features end-to-end, on schedule.
• Experience working day to day with designers and product managers.

Skills You Bring

• Technical Expertise
  • Expert-level React and Next.js (TypeScript required).
  • Strong understanding of design systems, design tokens, and component API design.
  • Strong fundamentals in state management, data fetching, rendering performance (Core Web Vitals), and testing.
  • Comfortable working from Figma designs and specs.
  • Experience with Storybook and at least one of CSS-in-JS, CSS Modules, or Tailwind CSS.
  • Working knowledge of web accessibility standards (WCAG).
• Collaboration
  • Clear communicator; able to articulate design and technical trade-offs to engineering, design, and product partners.
  • Comfortable building within an architecture someone else owns while still bringing an independent point of view.
  • Experience giving and receiving constructive feedback.

Nice to Have

• Experience translating motion design concepts into production-ready animations (Framer Motion, GSAP).
• Experience in high-growth DTC or e-commerce companies, ideally on a headless Shopify stack.
• Fluency with AI-assisted development (Claude Code, Cursor, or similar).
• Knowledge of A/B testing frameworks and experimentation methodologies.
• Background in health, wellness, or science-focused consumer brands.
• Experience at a consumer brand known for design craft and obsessive attention to detail.

Requirements

• The annual pay range for this full-time position is $160k-$180k + equity + benefits across all US locations (this position is 100% remote-US).
• Our pay ranges are guided by discipline, level and experience required. Within the range, individual pay may vary based on additional factors, including: your specific location, desired skills/technical competency, relevant experience and advanced education/training.
