Role Introduction

Were seeking a Network & Telephony Engineer to lead on-premise telephony infrastructure setup and SIP integration for our enterprise AI deployments at CozmoX AI. You will be responsible for designing, installing, and maintaining client-site network configurations, ensuring seamless voice communication capabilities. This is a hybrid role that combines deep technical SIP/VoIP expertise with strong deployment execution on client premises. Your work will directly impact the performance and quality of our AI voice employees across mission-critical environments.

Responsibilities

• Lead installation and configuration of SIP-based telephony systems, routers, and switches on client premises for CozmoX AI deployments.
• Integrate VoIP infrastructure with client PBX systems (Asterisk, FreePBX, Avaya, Cisco, etc.) ensuring low latency and high call quality.
• Work closely with CozmoX AI’s AI engineering and infra teams to define telephony requirements, call routing logic, and SIP trunking architecture.
• Configure SBCs (Session Border Controllers), firewalls, NAT traversal, and QoS settings to ensure secure and reliable voice traffic.
• Troubleshoot VoIP and SIP call flow issues using tools like Wireshark, sngrep, and SIP debuggers, ensuring uptime and performance SLAs are met.
• Conduct site surveys and assessments to evaluate network readiness and advise on infrastructure upgrades needed for AI voice employee performance.
• Collaborate with client IT teams and telephony providers to provision and test SIP trunks, DIDs, and number routing plans.
• Maintain documentation of telephony deployments, IP schemas, security configurations, and failover/redundancy planning.
• Provide L2/L3 support for all network and voice issues across active CozmoX AI client installations.
• Implement best practices for secure, redundant, and scalable voice networks to support 24/7 AI employee availability.
  
  

• 4+ years of hands-on experience with SIP-based VoIP deployments, including end-to-end integration and troubleshooting.
• Strong understanding of SIP protocol, SDP, RTP, and call flow diagnostics.
• Proven experience installing and configuring enterprise network equipment including routers, switches, SBCs, 3CX, and firewalls (e.g., Cisco, Fortinet, MikroTik).
• Familiarity with PBX platforms (Asterisk, FreePBX, Cisco CallManager, etc.) and cloud telephony platforms (Twilio, DID Logic, etc.).
• Proficient with tools like Wireshark, tcpdump, and sngrep for packet-level analysis.
• Comfortable working on client premises, often in collaboration with local IT teams, and managing end-to-end installations independently.
• Solid knowledge of IP networking, subnetting, VLANs, QoS, NAT, VPNs, and VoIP-related firewall rules.
• Bachelor’s degree in Telecommunications, Networking, or related technical field.
• Industry certifications preferred (e.g., CCNA, JNCIA, CompTIA Network+).
  
  

• Experience deploying voice infrastructure in BFSI, government, or healthcare environments.
• Knowledge of regulatory and compliance requirements related to telephony in MENA (e.g., TRA, CITC).
• Familiarity with remote monitoring and alerting tools (e.g., Zabbix, PRTG, Prometheus).
• Experience integrating AI-driven IVR or voicebot platforms.
• Ability to document systems clearly and hand off to internal/partner support teams.
• Strong client-facing skills and ability to coordinate cross-functional teams.
  
  

• Cutting-Edge Impact: Help deploy the voice infrastructure powering AI employees across major banks, governments, and hospitals.
• Ground-Level Innovation: Be on the front lines of a company redefining voice AI from infrastructure to the end customer.
• Autonomy with Ownership: Own entire deployments with independence and support from a high-performance technical team.
• Hybrid of Field and Cloud: Apply your skills in SIP, networking, and systems in both on-prem and cloud-integrated contexts.
• Mission-Driven Team: Join a company pushing the frontier of how humans and machines communicate, starting with voice.
