Full Stack Engineer (WordPress)

Role Overview We are seeking a Full Stack WordPress Developer to build and maintain scalable, high-performance, SEO-friendly websites. The ideal candidate will have deep experience across frontend, backend, QA testing, API integration, and deployment, with a focus on code modularity, system performance, and pixel-perfect execution. This role involves close collaboration with product managers, designers, and DevOps teams to ensure seamless delivery across environments. Key Responsibilities 1. Theme & Template Development ● Build or customize WordPress themes using a component-driven, modular architecture. ● Convert Figma designs into pixel-perfect, responsive HTML/CSS layouts. ● Maintain design consistency, brand alignment, and WCAG-compliant accessibility across pages. ● Build blocks for modular, reusable content creation. 2. Backend Development ● Configure custom post types, taxonomies, and custom fields (ACF Pro or equivalent). ● Develop custom plugins for specific business workflows or integrations. ● Write clean, secure, and scalable PHP/MySQL code following WordPress coding standards. ● Optimize database queries and caching mechanisms. ● Introduce error-logging and rollback handling for all critical backend updates. 3. Frontend Development ● Implement interactive UI components using JavaScript, jQuery, or React (when applicable). ● Ensure cross-browser and cross-device compatibility with mobile-first design. ● Follow WCAG 2.1 accessibility guidelines. ● Enable AJAX-based search, filters, and dynamic components. ● Use modern frontend build tools and enforce code linting/prettier checks. 4. API Integrations ● Integrate with external CRMs (Salesforce, HubSpot), LMS, or other enterprise systems via REST or GraphQL APIs. ● Implement authentication, caching, and error handling for external data exchanges. ● Build sandbox environments for testing integrations before production deployment. 5. DevOps, Versioning & Deployment ● Use Git for version control (feature → staging → production branches). ● Manage CI/CD pipelines for automated build, lint, and deployment processes. ● Maintain staging environments for QA validation and UAT. ● Perform environment variable and configuration management (via Composer, dotenv, etc.). ● Implement deployment checklists to ensure QA sign-off before any release. 6. SEO, Schema & Performance Optimization ● Follow on-page SEO best practices (semantic HTML, heading structure, canonical tags). ● Implement schema markup (JSON-LD) for relevant content types. ● Optimize Core Web Vitals, image compression, and lazy loading. ● Coordinate with analytics to validate GTM event tracking post-deployment. 7. Security, Compliance & Maintenance ● Regularly update WordPress core, themes, and plugins with regression testing. ● Apply security best practices (nonces, sanitization, validation, RBAC). 8. Quality Assurance (QA) & Testing ● Define and follow QA protocols across all development stages (unit, integration, and regression testing). ● Conduct functional testing for templates, forms, and custom features before deployment. ● Validate cross-browser and responsive layouts using real devices and tools (e.g., BrowserStack). ● Test API integrations for latency, data accuracy, and error handling. ● Perform UAT (User Acceptance Testing) with stakeholders before production rollout. ● Ensure accessibility, SEO tags, and analytics events are verified in each release. ● Create and maintain test cases and test reports for each release cycle. ● Implement automated testing where possible (e.g., PHPUnit for backend, Playwright/Cypress for UI regression). ● Collaborate with PMs and QA reviewers to log issues, track resolutions, and verify fixes before go-live. 9. Documentation & Knowledge Transfer ● Maintain developer documentation for code structure, APIs, and configuration steps. ● Prepare handover manuals and changelogs for internal or external teams. ● Maintain a QA & Release Log documenting test results, known issues, and resolutions for transparency. Preferred Qualifications ● 4–6 years of WordPress full-stack development experience in multi-site or enterprise environments. ● Proficiency in PHP, MySQL, JavaScript, HTML5, CSS3, and WordPress APIs. ● Experience with Gutenberg/ACF, WP-CLI, and build tools (Webpack/Vite). ● Familiarity with automated testing tools (PHPUnit, Cypress, Playwright). ● Strong understanding of CI/CD pipelines, Git workflows, and DevOps collaboration. ● Exposure to Salesforce, HubSpot, or LMS integrations. ● Knowledge of SEO, schema, accessibility, and analytics tracking. ● Understanding of QA processes and test automation frameworks for web projects. Success Metrics / KPIs ● Zero high-severity bugs post-deployment. ● Average page load < 2.5 seconds across key templates. ● 100% Core Web Vitals compliance on all major pages. ● QA checklist adherence across all releases. ● 95%+ reduction in rollback or hotfix instances due to pre-release QA validation. ● Updated documentation and release logs after every sprint
