About The Position

We are looking for a seasoned Senior WordPress & LMS Developer with deep expertise in Moodle, custom PHP development, and e-learning standards. You will architect, build, and maintain robust Moodle-based learning management systems serving thousands of learners — owning everything from database schema and REST API design to pixel-perfect front-end components and third-party integrations.
This is a high-impact, highly autonomous role suited to someone who thrives at the intersection of Moodle platform engineering and modern educational technology.

Requirements

• 5+ years of professional Moodle development including custom plugin authorship, theme development, and platform administration.
• Deep hands-on expertise with Moodle's plugin API, hook system, capability/role framework, gradebook API, and web services layer.
• Expert-level PHP 8+ including OOP, namespaces, Composer, and PSR standards.
• Solid command of MySQL / MariaDB: schema design, query optimisation, and migrations.
• Demonstrated hands-on experience with SCORM 1.2 / 2004, xAPI, and LTI integration — not just awareness of the specs.
• Strong JavaScript (ES6+) and experience with at least one modern front-end framework (React preferred).
• Proficiency with Git version control and collaborative branching strategies (GitFlow, trunk-based).
• Experience with REST API design and consumption, including authentication (OAuth, JWT, API keys).

Nice To Haves

• Hands-on experience with CMI5, AICC, or emerging IMS standards.
• Familiarity with an LRS (Learning Locker, SCORM Cloud, Watershed) and experience querying xAPI data.
• WooCommerce development experience including subscriptions, memberships, and custom payment flows.
• Experience with Moodle Mobile app customisation or Moodle's mobile web services.
• Experience with containerised development environments (Docker, Lando) and cloud deployments.
• Knowledge of accessibility standards (WCAG 2.1) and assistive technology testing.
• Contributions to the Moodle plugins directory or Moodle core codebase.
• Relevant certifications: Moodle Certified Developer, ADL xAPI, IMS Global LTI Advantage, AWS, or similar.

Responsibilities

• Design, develop, and maintain a scalable, high-availability Moodle platform — including site architecture, database optimisation, caching layers (Redis/Memcached), and multi-tenant or multi-instance configurations.
• Write clean, well-documented PHP 8+ code following OOP principles and Moodle's own coding style, APIs, and security guidelines (capability system, sesskey, SQL API).
• Build and maintain custom Moodle plugins (activity modules, blocks, authentication plugins, enrolment plugins, local plugins) following Moodle coding standards and plugin API conventions.
• Develop and customise Moodle themes using the Boost/Classic inheritance model, ensuring responsive, accessible, and branded learner experiences.
• Implement and troubleshoot SCORM 1.2 / 2004 course packaging, runtime communication, and completion tracking.
• Integrate xAPI (Tin Can) statements with Learning Record Stores (LRS) such as SCORM Cloud, Learning Locker, or custom solutions.
• Configure and maintain LTI (Learning Tools Interoperability) 1.1 and 1.3 / Advantage connections between WordPress/LifterLMS and third-party tools.
• Implement CMI5 course delivery where required, ensuring spec-compliant AU launch and data reporting.
• Develop responsive, accessible front-end experiences using modern JavaScript (ES6+) and Moodle's AMD/RequireJS module system, including custom Mustache templates and YUI/jQuery where required by legacy components.
• Integrate with Google Classroom via LTI Advantage (1.3), managing rostering, grade passback, and deep linking.
• Optimise Moodle performance via caching configuration, theme asset minification, and database query profiling. Ensure WCAG 2.1 AA accessibility compliance across all learner-facing interfaces.
• Collaborate with UX/UI designers and instructional designers to translate wireframes into polished Moodle theme components and activity layouts.
• Integrate Google Classroom with Moodle via LTI Advantage 1.3 — managing course rostering, assignment creation, grade passback, and deep linking.
• Configure Mindsmith-authored content for xAPI reporting, ensuring completion events and scores flow correctly to the LRS and Moodle gradebook.
• Connect third-party services (CRMs, HR/talent systems, videoconferencing) via Moodle's REST/SOAP web services API, external database enrolment, and custom authentication plugins.
• Design and document Moodle web service functions for mobile app support, headless consumers, and third-party system integrations.
• Integrate Zoom via LTI Pro to enable instructors and learners to launch, schedule, and record meetings directly within the LMS — including grade/attendance passback where applicable.
• Manage authentication flows including SSO via SAML 2.0 / OAuth 2.0 / OpenID Connect.
• Manage CI/CD pipelines for Moodle plugin and theme deployment using Git, GitHub Actions, or similar toolchains, including automated Moodle code checker (PHPUnit, Behat) test runs.
• Configure and optimise Moodle hosting environments (Nginx, Apache, PHP-FPM) on cloud infrastructure (AWS, GCP, or Azure), including Moodle's cron architecture and task scheduling.
• Conduct regular security audits, manage Moodle version upgrades, apply patches, and implement hardening measures specific to Moodle environments.
• Monitor, profile, and resolve performance bottlenecks in PHP, MySQL, and front-end assets.
• Lead code reviews, establish engineering standards, and mentor junior developers.
• Translate business and instructional-design requirements into clear technical specifications.
• Communicate progress, risks, and architectural decisions clearly to both technical and non-technical stakeholders.

Benefits

• Competitive salary
• performance bonuses
• equity / profit-sharing (role dependent)
• Annual professional development budget for courses, conferences, and certifications.
