• Lead the software and telephony engineering functions, setting high standards for code quality, architectural design, and engineering practices across all domains.
• Drive enhancements to telephony infrastructure, ensuring reliability, scalability, and performanceparticularly within Asterisk-based call routing, IVR, and SIP integration workflows.
• Embed a culture of automation and reliability, integrating CI/CD pipelines, Infrastructure as Code, and observability into daily delivery workflows.
• Champion secure coding and security-by-design practices across both software and telephony systems, ensuring robust authentication, input validation, and dependency management.
• Ensure clear documentation and traceability of designs and decisions across application, telephony, and infrastructure components.
• Lead periodic reviews to validate code quality, architectural integrity, telephony performance, and maintainability.
• Drive continuous quality improvement by embedding automated testing, including telephony-specific test harnesses and call-flow validation.
• Partner closely with Product Management while leading QA and DevOps to deliver scalable, business-aligned, and telephony-reliable solutions.
• Mentor and develop engineers into specialized roles (backend, frontend, DevOps, QA, telephony/VoIP), fostering expertise and career growth.
• Establish engineering delivery discipline and practices that improve predictability, transparency, and cross-team collaboration.
• Guide the adoption of event-driven and asynchronous architectures where appropriate for scalability and call-routing performance.
• Continuously evaluate new technologiesincluding emerging telephony and voice technologiesto ensure the product remains competitive and resilient.
• Collaborate with Architecture, Product, and Security leaders to ensure technical decisions balance business value, telephony reliability, long-term scalability, and compliance.

3. Technical and Professional Competencies

• Deep hands-on experience in software engineering, systems architecture, and technical leadership, with strong telephony and VoIP expertise.
• Mandatory experience in Asterisk development, including dialplan creation, AGI/AMI/ARI integrations, SIP/RTP handling, call-flow optimization, and performance tuning.
• Strong understanding of telephony protocols (SIP, RTP, STUN/TURN/ICE, WebRTC) and real-time communication systems.
• Strong hands-on experience with Python for backend development, microservices, and automation.
• Working knowledge of AI/ML concepts, frameworks, and practical application of machine-learning models within production systems (advantage).
• Proficiency in modern programming languages and frameworks, including experience with API design and distributed systems.
• Experience transitioning from monolithic architectures to modular, cloud-native, or microservice patterns.
• Strong background in cloud platforms (AWS preferred), including scalability, observability, and cost-optimized deployments.
• Experience implementing CI/CD pipelines, Infrastructure as Code, and containerized deployments (e.g., Docker, Kubernetes).
• Proven ability to embed automated testing, code reviews, and DevOps best practices into engineering workflows.
• Strong understanding of application, telephony, and network security.
• Excellent analytical skills and the ability to balance technical depth with strategic oversight.
• Ability to translate complex technical and telephony-related challenges into business value for stakeholders.

4. Technical Environment

The Head of Engineering is expected to be hands-on in reviewing and guiding development across this stack, with a special focus on telephony modernization and Asterisk systems:

• Telephony: Asterisk (core telephony engine, SIP routing, IVR, AGI/ARI), VoIP infrastructure
• Backend: PHP with Laravel, Python for microservices
• Frontend: ReactJS
• AI/ML (optional but beneficial): Experience with Python-based ML frameworks
• Databases: MariaDB/MySQL and MongoDB on AWS RDS and MongoDB Cloud
• Cloud Platform: AWS (EC2, S3, RDS, CloudWatch, SES, CodePipeline)
• Infrastructure: Ansible for Infrastructure as Code
• Automation & Observability: CI/CD pipelines in AWS CodePipeline, Zabbix, CloudWatch
• Security & Networking: OWASP, VPN
• Additional telephony/RTC tools: SIP providers, SBCs, RTP monitoring (advantage)

5. Behavioural Competencies

• Leads by example with accountability, technical curiosity, and a commitment to quality and reliability.
• Promotes a culture of innovation, learning, and continuous improvement.
• Encourages collaboration and shared ownership across teams.
• Balances delivery urgency with long-term architectural and telephony system sustainability.
• Communicates clearly and influences effectively across technical and non-technical audiences.
• Drives a shift from reactive delivery to proactive engineering excellence and preventative quality practices.

6. Qualifications & Experience

• Minimum Bachelors degree in Computer Science, Software Engineering, or related fieldor equivalent hands-on experience.
• Minimum 15 years of experience in software engineering, including at least 8+ years in technical or team leadership roles.
• Proven hands-on experience in telephony/VoIP systems and Asterisk development (non-negotiable).
• Demonstrated experience using Python in backend systems or automation workflows, with exposure to AI/ML technologies being an advantage.
• Demonstrated success leading engineering teams in a product-based or platform-based environment.
• Experience modernizing systems for scalability, maintainability, and securityboth in software and telephony domains.
