Role Summary

We are seeking an accomplished VoIP Architect to lead the design and optimization of scalable, secure, and high-performance real-time communication systems at a global scale. In this role, you will define and implement VoIP architectures that deliver low latency, high call quality, and seamless integration across multiple platforms and devices.

The ideal candidate brings deep expertise in VoIP protocols (SIP, RTP/RTCP, WebRTC), audio/video codecs, and real-time networking, with a proven track record of building and scaling production-grade communication platforms. Beyond core architecture, you will drive innovation by adopting emerging technologies, enhance system reliability through proactive performance optimization and security measures, and provide technical leadership in troubleshooting complex VoIP challenges.

Responsibilities

• Architecture Design: Design and implement scalable, reliable, and secure VoIP architectures that meet the demands of global-scale communication.
• Performance Optimization: Optimize VoIP systems for low latency, high call quality,
  and efficient bandwidth usage. Identify and resolve bottlenecks to improve system
  performance and user experience.
• Integration: Collaborate with cross-functional teams to integrate VoIP services with
  existing messaging and multimedia systems. Ensure seamless compatibility with
  multiple devices and platforms (iOS, Android, desktop, etc.).
• Security and Compliance: Implement robust security protocols to protect user data
  and prevent fraud. Ensure compliance with global telecommunication standards and
  regulations.
• Innovation: Stay up-to-date with emerging technologies and trends in VoIP and
  real-time communication. Lead initiatives to introduce new technical features and
  enhance existing functionalities.
• Troubleshooting and Support: Provide technical guidance to the development and
  operations teams for resolving critical VoIP-related issues. Conduct root cause analysis of system failures and implement preventive measures.

• 10+ years of experience in VoIP architecture, design, and implementation.
• Proven track record of building and scaling VoIP systems in production environments.
• In-depth knowledge of VoIP protocols such as SIP, RTP/RTCP, SDP, WebRTC, and
  STUN/TURN.
• Experience with audio and video codecs (e.g., Opus, H.264, VP8, VP9).
• Proficiency in programming languages like C++, Python, or Rust, Go, Erlang.
• Familiarity with cloud platforms (AWS, GCP, Azure) and containerization tools (Docker, Kubernetes).
• Strong understanding of networking principles, including QoS, NAT traversal, and
  firewall configuration. Experience with troubleshooting network issues in real-time
  communication systems.
• Excellent analytical and problem-solving abilities, especially in diagnosing
  VoIP-related issues.
• Strong communication skills to collaborate effectively with cross-functional teams.
• Adopt emerging technologies, such as AI to enhance productivity and drive
  innovation in development.
• Strong English communication skills for seamless collaboration with teams.
