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 modern 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.
- Solid command of Linux internals, network diagnostics (packet capture, QoS, routing), and cloud infrastructure architecture.

Good-to-Have

- Familiarity with regulatory frameworks and compliance controls (PCI-DSS, HIPAA, SOC 2, ISO 27001).
- Experience with containerization and orchestration architectures tailored for real-time UDP/RTP media streaming.
- Relevant industry certifications (e.g., CISSP, CISM, CEH, or advanced Cloud Architect/Security credentials).
