OpenCart Developer (In-House) - Ecommerce Web Developer

We are bringing our website development and hosting fully in-house.

This is an exciting new role and a rare chance to take full ownership of a high-traffic ecommerce platform., As our in-house OpenCart Developer you will be responsible for developing, maintaining and improving our ecommerce websites across frontend and backend development, implementation, testing, deployment and ongoing support. You will take the site over from our current agency, migrate it onto our own server, and then run and develop it day to day. You will work alongside our ecommerce and marketing team, and with selected third-party partners where needed., · Develop, customise and maintain OpenCart functionality across our ecommerce website, frontend and backend.

· Build custom OpenCart modules and modifications without altering OpenCart core code, using OCMOD and the modification system.

· Integrate OpenCart with third-party and in-house services using the OpenCart REST API and other web APIs.

· Work confidently with OpenCart's MVC(L) architecture: controllers, models, libraries and the event and hook system.

· Configure and maintain OpenCart's theme, template and layout layer, including Twig templates.

· Develop and support frontend functionality using JavaScript, jQuery, AJAX and the OpenCart theme system.

· Use CSS preprocessors such as SCSS, SASS or LESS to support maintainable frontend development.

· Plan and carry out the migration of the site from our current managed host onto our own server, with zero disruption to trading.

· Improve site speed, stability and Core Web Vitals, and keep the platform secure and up to date.

· Build and maintain product feeds to Google Merchant Center and Shopping, payment gateways, and links to our order management, stock and accounting systems.

· Troubleshoot and resolve issues with new and existing custom code.

· Work closely with marketing, other stakeholders and third-party resources to enhance functionality and improve conversion.

· Work independently when required, taking ownership of assigned development tasks from brief through to deployment.

· Use Git for version control and contribute to a clean, controlled development workflow.

This role would suit someone with strong OpenCart coding experience, a practical problem-solving approach, and the ability to communicate clearly with both technical and non-technical colleagues. It is a hands-on, high-autonomy role for someone who enjoys owning a platform rather than being one cog in a large team., · At least 3 years of OpenCart development experience (version 3, and ideally 4).
