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.
