About Our Client

Our client is an early-stage, fast-growing fashion marketplace based in New York, transforming how South Asian formalwear is rented and resold.

Built on the success of an established fashion business with over 7,000 customers, 2,000+ completed rentals, and more than $1.1M in revenue, they are now scaling their technology platform while preparing for their next stage of growth.

Their mission is to build the leading peer-to-peer marketplace for South Asian formalwear, combining beautiful user experiences with robust marketplace infrastructure. The product is already live and processing real transactions, and the team is working toward an ambitious product milestone ahead of the 2026 wedding season.

This is an opportunity to become the company's lead engineer, working directly with the founder and designer while taking full ownership of the technical roadmap.

Role Overview

As the Senior Full Stack Developer, you will own the entire product codebase and lead the technical execution of a rapidly growing marketplace platform.

You'll work directly with the founder and a dedicated UI/UX designer, making key architectural decisions while delivering new product features across web and mobile. There is no management layer between you and business decisions, making this an ideal role for someone who enjoys autonomy, product ownership, and close collaboration with non-technical stakeholders.

One of your first major objectives will be delivering a polished mobile application for both iOS and Android while continuously improving the marketplace experience and expanding platform capabilities.

This is initially a 3-month contract, with a strong possibility of long-term extension based on performance.

Responsibilities

• Own and maintain the company's entire Next.js codebase.
• Design, develop, and ship high-quality product features across frontend and backend.
• Lead the technical strategy for the company's mobile application (React Native with Expo, Capacitor, or alternative approach).
• Deliver production-ready iOS and Android applications.
• Collaborate closely with the founder and UI/UX designer to create intuitive and polished user experiences.
• Build and improve marketplace workflows, including rentals, payments, notifications, and logistics.
• Develop new features related to garment care, dry-cleaning operations, inventory condition tracking, and operational workflows.
• Maintain and optimize PostgreSQL databases and backend services.
• Ensure application quality through testing strategies, debugging, and performance improvements.
• Participate in architectural decisions and recommend the best technical solutions for product evolution.
• Communicate technical concepts effectively with non-technical stakeholders and help translate business ideas into product features.
• Work independently while maintaining high engineering standards and shipping consistently.

Requirements

• 5+ years of experience building modern web applications.
• Strong expertise with Next.js, React, TypeScript, and modern JavaScript development.
• Solid backend development experience.
• Strong experience with PostgreSQL or other relational databases.
• Experience owning production systems and live databases.
• Experience developing and publishing mobile applications using React Native (Expo), Capacitor, or similar technologies.
• Experience releasing applications to the Apple App Store and Google Play Store.
• Strong understanding of software architecture and scalable application design.
• Experience collaborating closely with product designers and translating Figma designs into polished user experiences.
• Knowledge of software testing methodologies and production-quality engineering practices.
• Ability to work autonomously with minimal supervision.
• Excellent communication skills and ability to collaborate with founders and non-technical stakeholders.
• Availability to work primarily during New York (Eastern Time) business hours.

Nice to Have

• Experience building marketplace platforms.
• Background in e-commerce products.
• Previous experience in Fashion Retail, Fashion Technology, or Fashion E-commerce (highly valued).
• Experience with Stripe Connect, including marketplace payments, escrow flows, manual capture, and off-session charging.

• Compensation in USD.
• Fully remote work.
• Full-time opportunity with a high level of autonomy and ownership.
• Direct collaboration with the founder and product designer.
• Opportunity to lead the technical direction of a growing startup.
• Career growth in an international company.
• High probability of contract renewal after the initial 3-month engagement based on performance.
