About Pickle

Pickle is a peer-to-peer rental marketplace unlocking the value of the billions of underutilized items sitting in consumers’ closets. We make it easy to rent high-quality items exactly when you need them — with fast, convenient fulfillment and an on-demand experience that’s as seamless as shopping.

We’re building a new kind of commerce layer: one powered by dynamic local supply, where access is more convenient than ownership. Pickle is now live nationwide and scaling rapidly in key local markets including NYC, LA, and Miami
. Our marketplace already features 300K+ items listed for rent
, and we’re just getting started.

What makes Pickle different is the combination of incredible peer-to-peer inventory
, industry-leading convenience (2 days nationwide and 2 hours locally
), and an on-demand model with no subscriptions — users rent what they want, when they want it. Backed by our Series A funding raised in early 2025 from First Mark and Craft
, we’re scaling quickly and building the future of access-driven shopping.

We are building a single, unified React codebase that powers both Web (Next.js) and Mobile (Expo / React Native). As a Senior Frontend Engineer, your mission is to architect the React layer so that business logic, hooks, and UI primitives are shared by default, while still delivering a truly native mobile experience.

We are explicitly looking for a React expert — someone who understands React deeply and can design scalable, high-performance frontend systems.

If you think deeply about component composition, rendering behavior, state boundaries, and long-term maintainability — and you enjoy solving the hard frontend problems — this role is for you.

• React Architecture & Monorepo Design
• Architect frontends across web (Next.js) and mobile (React Native) in a monorepo environment
• Define clear boundaries between shared packages (packages/ui, packages/hooks) and platform-specific implementations.
• Design components and hooks to minimize re-renders and maximize performance.
• Make deliberate decisions around memoization, referential stability, and component granularity.
• Own the frontend state architecture by mixing local and global state solutions and working with backend team to define client/server logic boundaries
• Complex UI & Frontend Logic
• Lead implementation of the most complex frontend flows, including multi-step booking calendars, conflicting availability logic, and dynamic filtering interfaces.
• Design and maintain navigation architecture.
• Ensure deep linking works consistently across platforms
• Enforce strict Type Script standards across components, hooks, and APIs.
• Efficiently consume mixture of RPC and REST based backend components to power frontend.
• Mobile-First Execution & Frontend Standards
• Ensure the shared architecture produces a truly native mobile experience.
• Handle safe areas, keyboard avoidance, hit slops, touch feedback, and platform-specific nuances.
• Set the standard for frontend code quality and best practices.
• Lead thoughtful code reviews focused on React patterns, hooks design, and platform-agnostic architecture.
• Mentor other engineers on writing scalable, maintainable frontend code.

• Deep expertise in React, including rendering behavior, reconciliation, and hooks.
• Experience in Next.js, especially versions 15+ using the pages router and server components
• Experience incorporating modern component libraries (ShadCN, Mantine, etc.)
• Ability to write clean, maintainable CSS using modern tooling (Tailwind, Styled Components, etc.)
• Strong experience working in a monorepo environment (Turborepo, Nx, or Lerna).
• Experience working with modern global state solutions (Zustand, Jotai, Redux)
• Experience working with client data fetching and caching libraries (React Query, Apollo client, Urql)
• Experience sharing code between React DOM (Web) and React Native.
• Experience with modern React Native toolchain (React Navigation, Flashlist, Metro/Babel, Expo, etc).
• Advanced Type Script skills, including strict and generic-heavy typing.
• Experience implementing complex frontend business logic (booking flows, date manipulation, cart systems, optimistic updates,…
