Key Responsibilities

• Infrastructure Modernization & IaC: Transition existing distributed server environments into automated, codifiable, and declarative infrastructure (Infrastructure as Code).
• Delivery Pipelines: Design, implement, and institutionalize robust CI/CD pipelines to ensure predictable, zero-downtime application and service deployments.
• Resilience & Reliability: Architect and enforce enterprise-grade High Availability (HA) topologies, multi-region failover, and comprehensive Disaster Recovery (DR) strategies for latency-critical voice services.
• FinOps & Resource Optimization: Establish active infrastructure monitoring, capacity planning, and resource right-sizing to optimize operational spend without compromising performance.
• Proactive Security & VAPT: Lead hands-on vulnerability assessments and penetration testing (VAPT), prioritize exposure remediation, and establish continuous security hygiene across networks, endpoints, and containers.
• Voice Network Operations: Maintain, scale, and harden mission-critical VoIP infrastructure, ensuring carrier-grade uptime,



minimal jitter, and zero packet loss.

Qualifications

Must-Have:

• 15+ years of progressive infrastructure, DevOps, and security experience, including leadership in architecting distributed systems.
• Deep domain expertise in real-time voice infrastructure: VoIP protocols (SIP, RTP/RTCP), Freeswitch, Asterisk PBX, SIP proxies/SBCs (Kamailio, OpenSIPS), and low-latency network tuning.
• Proven track record of leading zero-to-one infrastructure transformations, replacing manual server administration with automated Infrastructure as Code (Terraform, Ansible).
• Hands-on experience building and standardizing up-to-date CI/CD pipelines from the ground up.
• Demonstrated success designing and validating production HA/DR architectures and business continuity plans.
• Hands-on proficiency conducting internal/external VAPT, threat modeling, and managing security incident remediation workflows.
