Essential Requirements

Experience in Moodle and PHP (+5 years): Advanced mastery of PHP 8.x, direct development of custom plugins, Moodle APIs (Database, Cache, Events, Tasks, Form API), Mustache templates, migrations with db/upgrade.php, and compatibility with modern versions (4.x branches).

QA, Testing, and Clean Code:

Strict commitment to Clean Code standards and SOLID principles.

Advanced mastery of PHPUnit with a requirement for high code coverage in plugins.

Practical mastery of Behat (BDD) for automated functional testing in Moodle.

Databases and Concurrency: Advanced optimization in MySQL or PostgreSQL, index design, ACID transactions, and control of contention and locking (table/row locks) under high transactional concurrency.

Runtime, Web Servers, and Cache: Adjustments and optimization of the execution environment: PHP configuration (php.ini, OPcache), web server tuning (Apache / Nginx with PHP-FPM), and distributed and persistent cache layers (Redis, MUC).

Environments, Git, and CI/CD Automation:

Configuration of local environments with Docker.

Advanced use of Git (branching flows, code reviews, merge requests, and pull requests).

Practical experience in configuring CI/CD pipelines (GitHub Actions, GitLab CI, or similar) for automatic test validation and deployments.

AI Development and Interpersonal Skills: Habitual use of AI assistants in programming, technical judgment to audit and validate generated code, and empathetic and constructive communication when performing technical reviews.

Valuable Requirements

AWS Cloud Services: Practical knowledge in deploying and operating Moodle on AWS (EC2, RDS, S3, load balancers, and cache layers with ElastiCache/Redis).

Experience in massive exam platforms, online certification systems, or integration of proctoring tools.

Stress testing and performance analysis using JMeter or APM/profiling tools.

Knowledge of modern PHP frameworks (Symfony / Laravel) as a basis for software architecture and OOP best practices.

Position: Software Architect & Tech Lead - Moodle & AI-Assisted Dev

About the Role

We are looking for a Hands-on Software Architect to take on the technical design, scalability, and direct development of the solution, implemented entirely on the Moodle ecosystem.

The role combines active programming in PHP 8.x, modular plugin development on Moodle, and strict application of Clean Code, TDD (PHPUnit), and BDD (Behat). The position drives the adoption of generative Artificial Intelligence assistants to accelerate coding, focusing technical effort on architecture, test coverage, automation in pipelines, and rigorous and constructive code review.

Key Responsibilities

100% Moodle Architecture and Development: Design and program the solution directly through modular extensions, custom plugins (local_, mod_, tool_), hooks, Moodle internal APIs, and Mustache templates, guaranteeing high availability during massive concurrent assessments.

QA, Testing, and Coverage Strategy: Ensure integral software quality by applying TDD methodology with high unit test coverage (PHPUnit) and behavior-driven functional tests (Behat) on Moodle developments.

Lifecycle, Asynchrony, and Traceability: Manage background tasks (Scheduled and Ad-hoc Tasks), update scripts, data schema evolution (db/upgrade.php), and design audit logs for immutable traceability of exam events.

Native Integrations: Implement communication with external systems (payment gateways, proctoring/supervision tools, ERPs) through Moodle's native Web Services and RESTful APIs.

Performance, Runtime, and Concurrency: Optimize database transactions to prevent concurrent blocking (deadlocks / table locks), manage cache layers (MUC, Redis), and adjust the PHP runtime (php.ini, OPcache) and web server (Apache / Nginx with PHP-FPM) during massive assessment peaks.

AI-Assisted Flows and Technical Review: Integrate AI tools into the development flow to optimize deliveries, performing critical code reviews to ensure compliance with architecture standards, security (OWASP), and the absence of technical debt.

Environments, CI/CD, and Version Control: Maintain reproducible environments with Docker, manage collaborative flows in Git, and configure continuous integration and deployment (CI/CD) pipelines for automated test execution and quality gates.

Work modality: Negotiable hybrid.

Position: Technical leadership with active development (hands-on) in a strategic product.

Remuneration: Competitive salary according to the experience provided.
