Job description

Forix is a US-based leader in eCommerce design, development, and support, delivering high-performance online stores for global clients. We work with leading platforms such as Magento, Shopify, and BigCommerce. With our growing demand for BigCommerce projects, we are looking for a BigCommerce Front-end/Theme Development Lead to guide our team in building scalable, high-quality themes that deliver outstanding shopping experiences.

As the BigCommerce Front-end/Theme Development Lead, you will take ownership of front-end architecture and theme development strategy within the BigCommerce ecosystem. You will not only develop custom themes yourself, but also mentor other developers, enforce coding standards, and lead the adoption of best practices. The ideal candidate can extract and integrate data directly into themes via APIs — without depending on back-end developers — and can scale their expertise across the team.

• Lead the end-to-end development of custom BigCommerce themes using the Stencil framework.
• Define, document, and enforce front-end development best practices for BigCommerce projects.
• Mentor and guide junior/mid-level developers, conducting code reviews and providing feedback.
• Collaborate with project managers, designers, and clients to scope requirements and ensure technical feasibility.
• Integrate data and features directly into themes using BigCommerce APIs, GraphQL, and Handlebars.js.
• Drive performance optimization efforts, ensuring all themes are fast, scalable, and SEO-friendly.
• Proactively identify opportunities to improve workflows, tooling, and coding standards.
• Stay up to date with BigCommerce platform updates, Stencil enhancements, ADA compliance, and Core Web Vitals.
• Act as the go-to expert for all BigCommerce theme-related challenges and solutions within the team.

Your skills and experience

• 5+ years of front-end development experience, with at least 3 years in BigCommerce theme development.
• Mastery of Stencil framework, Handlebars.js, JavaScript (ES6+), HTML5, CSS3/SASS, and jQuery.
• Strong expertise in BigCommerce APIs (REST & GraphQL) and data integration.
• Proven experience leading projects or mentoring developers in a team environment.
• Solid understanding of performance optimization, SEO, accessibility (ADA), and security best practices.
• Excellent leadership, communication, and problem-solving skills.
• Ability to manage multiple projects in a fast-paced, agile environment.
• Familiarity with Git and modern development workflows.
