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
