- Customize and extend Vicidial features to meet evolving business requirements.

- Optimize database queries and system performance for high-volume call center operations.

- Troubleshoot and resolve complex technical issues in the Vicidial ecosystem.

- Collaborate with AI engineers to integrate machine learning capabilities into the call center workflow.

- Document technical specifications, API endpoints, and system architecture.

- Mentor junior developers and provide technical guidance to the team.

- Plan and execute the gradual migration strategy toward a modern, multitenant architecture.

Required Skills & Experience :

Must-Have :

- 3 - 5 years of hands-on experience in PHP development with production-level applications.

- Strong expertise in Vicidial installation, configuration, customization, and administration.

- Deep understanding of Vicidial's database schema, dialplan logic, and core modules.

- Proven experience in building RESTful APIs with PHP (Laravel/Symfony/native PHP).

- Strong knowledge of MySQL/MariaDB optimization and complex query writing.

- Experience with Asterisk PBX configuration and dialplan scripting.

- Understanding of telecommunication protocols (SIP, RTP, WebRTC).

- Experience with Docker and containerization.

- Knowledge of CI/CD pipelines and DevOps practices.

- Familiarity with multitenant SaaS architecture.

- Experience with WebSocket and real-time communication.

- Previous work with AI-powered call center solutions.

- Understanding of JWT authentication and OAuth protocols.

- Experience with Redis/Memcached for caching.

- Knowledge of message queuing systems (RabbitMQ, Kafka).

What We're Building :

You'll be instrumental in our transition from a monolithic Vicidial-based system to a modern, scalable, multitenant contact center platform with :

- React-based frontend for superior user experience.

- Node.js backend for microservices architecture.

- Python-based AI engine for intelligent call handling.

- AWS cloud infrastructure for scalability and reliability.

- API-first design for seamless integrations.

What We Offer :

- Opportunity to architect and lead a critical technology transition.

- Work with cutting-edge AI and cloud technologies.
