Entry Level React Native Expo Jobs in Park Ridge, NJ

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(under 2 days nationwide and under 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 FirstMark and Craft, we're scaling quickly and building the future of access-driven shopping.
About the role
This is a full-stack engineering role at the center of how Pickle works.
You will build and ship features across the entire stack. From the React and React Native interfaces our renters and lenders use every day, to the APIs, services, background jobs, and database layers that power them.
You will own product problems end to end: understanding what needs to be built, designing the technical approach, implementing it across the stack, and iterating once it's in users' hands.
The domains you work in will evolve with the product. One quarter you might be building rental booking flows or marketplace payments; the next, improving the AI assistant, search infrastructure or performance across mobile and web.
What stays constant is the expectation that you:

• Think in systems
• Write code other engineers can build on
• Care deeply about the experience we ship to users
• Move fast without cutting corners
• Keep learning in every step

If you enjoy owning real product surface area and building something people actually use then this role is for you.
What You'll Do
End-to-End Product Ownership

• Collaborate with product and design to scope and shape new features.
• Design clean technical approaches before writing code.
• Implement solutions across frontend, backend, and database layers.
• Iterate quickly based on user feedback and data.

Frontend Engineering (Web & Mobile)

• Build high-quality user interfaces using React (Next.js) and React Native (Expo).
• Manage complex client-side state and asynchronous data flows.
• Optimize performance, rendering behavior, and responsiveness.
• Maintain strict TypeScript contracts between frontend and backend.

Backend & API Development

• Design and implement type-safe APIs using tRPC.
• Own business logic in the service layer, not the UI.
• Build and maintain background jobs and asynchronous workflows.
• Ensure APIs are performant, secure, and easy to consume.

Data & Architecture

• Design and evolve Postgres schemas.
• Write efficient queries and optimize performance.
• Maintain clean domain boundaries within our Turborepo.
• Contribute to architectural decisions as the system scales.

AI-Augmented Development

• Use AI coding agents to multiply your output.
• Understand where AI accelerates work and where it falls short.
• Treat AI as a force multiplier, not a crutch.
• Maintain ownership and accountability for every line of code shipped.

Leveling Expectations
We are hiring across multiple levels. Scope and autonomy will scale with experience.
Junior Engineers

• Contribute to well-scoped features with guidance.
• Learn our architecture and engineering standards.
• Develop strong fundamentals in React, APIs, and database design.
• Write clean, well-tested code and actively seek feedback.

Mid-Level Engineers

• Own features end to end with minimal oversight.
• Contribute to architectural discussions.
• Improve performance, reliability, and developer experience.
• Mentor junior engineers informally.

Senior Engineers

• Own large product surfaces or technical domains.
• Design systems that other engineers build on.
• Set patterns for frontend, backend, or data architecture.
• Drive quality through thoughtful code reviews and standards.

Staff-Level Engineers

• Think in multi-quarter architectural horizons.
• Identify systemic risks and scalability constraints before they become problems.
• Influence engineering culture and technical direction.
• Lead complex cross-functional initiatives across product and platform.

Required Qualifications

• Professional experience building and shipping full-stack applications.
• Familiarity with TypeScript.
• Experience building production APIs (REST, GraphQL, or RPC).
• Experience working with relational databases (Postgres preferred).
• Experience building user interfaces with React.
• Comfort operating in a fast-moving product environment.

Nice to Have

• Experience with React Native or Expo.
• Experience with tRPC or strongly typed API layers.
• Experience working in a monorepo (Turborepo, Nx, etc.).
• Experience in marketplace, payments, or search-heavy products.
• Experience designing scalable systems beyond a single service.

Our Stack

• Frontend: React (Next.js), React Native (Expo)
• Backend: TypeScript, oRPC
• Database: Postgres (Supabase), Redis, OpenSearch
• Architecture: Turborepo (Monorepo), Modular Services
• Infrastructure: AWS, Vercel, Snowflake

How We Work

• We value clean domain boundaries and type safety.
• We prioritize pragmatic architecture over theoretical purity.
• We believe in shipping quickly and improving continuously.
• We use AI tools thoughtfully to move faster - without lowering the bar.

If you want to build a real product used by real people, own meaningful surface area, and grow alongside a fast-moving team - we'd love to meet you.
