• Debug complex frontend issues across various browsers and devices.
• Contribute to improving frontend standards, architecture, and best practices.

• Proven experience building production storefronts or web products.
• Bachelor's degree in Computer Science / IT or a related field is preferred.

Why Join Us:

Join a team that builds engineering-driven storefronts, not just template edits. You will work on CRO, performance, and scalable theme architecture, gain exposure to complex eCommerce systems and high-impact projects, and benefit from a clear technical ownership and growth path (Senior / Lead Theme Engineer).
