About our hiring partner

Our hiring partner is the leading partnership marketplace that connects top ecommerce brands so they can sell more together without taking on inventory risk. Thousands of retailers discover new products through their platform every month, and they're just getting started.

Why this role now

Earlier this year, our hiring partner acquired another company to unite two leading platforms in the ecommerce dropshipping space. They're now building a new, combined marketplace from the ground up and are looking for a senior front-end engineer to own the entire UI layer, shaping both the foundation and the future of this product.

What you'll do

  • Own the front-end architecture. Design, implement, and evolve a modern React codebase (TypeScript, Vite, Vitest) running in Google Cloud Platform.

  • Ship beautiful, accessible experiences. Work hand-in-hand with product & design to turn Figma files into pixel-perfect UIs that feel simple and light.

  • Sweat the details. From animation curves to micro-copy, you notice and polish the 1% that delights users.

  • Champion performance. Monitor and improve Core Web Vitals.

  • Evolve our design system. Create reusable, documented components that make the right thing the easy thing for the whole team.

  • Collaborate on API design. Work closely with backend engineers to design REST APIs that power our user experiences.

What you bring

  • 6+ years building production web apps with React and modern JavaScript/TypeScript.

  • A portfolio or live product that demonstrates impeccable attention to spacing, typography, and interaction states.

  • Deep knowledge of semantic HTML5, CSS architecture, and responsive design.

  • Experience optimizing bundle size and runtime performance.

  • Comfortable working in cloud-native environments (we deploy to Google Cloud Storage + Cloud CDN).

  • Strong communication skills and a collaborative, product-driven mindset.

Bonus points

  • Experience with ecommerce or marketplace products.

  • Familiarity with Redux Toolkit, React Query, Emotion, or Storybook.

  • Past contributions to design systems or open-source libraries.

How we work

  • Users first. We exist to create user value, everything else follows.

  • Craft matters. We obsess over polish and consistency.

  • Touch the ball more. We bias toward small, frequent releases to learn faster.

  • Own the outcome. We trust you to see problems through from concept to launch and iteration.

Salary Range

60-80K depending on cultural fit, experience and background.
