About the Role

We are looking for a Product Engineer who is highly product-minded, fast-moving, and comfortable owning front-end development in a startup environment. This role sits at the intersection of engineering, product thinking, and execution, with a strong emphasis on Point of Sale (POS) systems.

You will work closely with founders and engineers to build, improve, and scale a POS platform used on tablet devices. While the team has strong backend coverage, the biggest need is on the front end, particularly around React, TypeScript, and React Native.

This is a hands-on role for someone who enjoys moving quickly, shipping features, and maintaining high UI and code quality while working in an AI-accelerated development environment.

Key Responsibilities

Own and build front-end features for a POS product used primarily on tablet devices
Work extensively with React, TypeScript, and React Native (some Next.js exposure)
Improve UI/UX quality and refactor existing codebases to maintain performance and cleanliness
Collaborate closely with backend engineers while focusing primarily on front-end delivery
Apply strong product thinking: understand the product deeply and translate requirements into high-quality implementations
Help guide and mentor other developers when needed
Move fast in a startup environment while maintaining code quality
Leverage AI tools in development workflows while ensuring long-term maintainability

Required Experience & Skills

Mandatory experience working with POS (Point of Sale) systems
Strong experience with React and TypeScript
Hands-on experience with React Native (tablet or mobile applications)
Solid front-end engineering background with a product-focused mindset
Experience working in startup or fast-paced environments
Comfortable shipping features quickly and iterating based on feedback
Ability to balance speed and code quality in AI-assisted development
5+ years of professional experience preferred (flexible based on candidate fit)

Nice to Have

Experience with Next.js
Experience guiding or mentoring engineers
Familiarity with AI-driven development workflows
Experience working on B2B SaaS or fintech products

What We’re Looking For

Product-first engineers who understand why they’re building something, not just how
Engineers who thrive in fast-moving environments and enjoy ownership
Candidates who care deeply about UI quality and performance
People who communicate clearly and collaborate well with founders and teammates
