Responsibilities

• Develop and maintain software interfaces in C++ and C# between PBX and voice switching platforms, endpoint devices, and back-end web services.
• Implement and integrate SIP for call setup, routing, and teardown, and manage RTP media streams for real-time voice transport.
• Build SNMP-based monitoring and management interfaces to query, configure, and collect health and status data from telephony devices.
• Design RESTful or equivalent API integrations between the voice layer and back-end services to ensure reliable data exchange and state synchronization.
• Develop and integrate web service interfaces using REST, JSON, WebSocket, or SOAP for robust communication between systems.
• Apply strong networking fundamentals, including TCP/UDP, NAT, and QoS, to design and troubleshoot communication paths.
• Conduct independent research to identify, evaluate, and implement new technical solutions to complex problems.
• Collaborate closely with systems and hardware engineering teams to resolve technical issues and align software with system requirements.
• Debug embedded software issues in near real-time simulation environments to ensure performance and reliability.
• Prepare and deliver technical presentations and documentation to communicate design decisions, system behavior, and solution approaches.

Essential Skills

• 7+ years of software development experience using C++ or C#.
• Proficiency in developing software interfaces for communication between PBX/voice switching platforms, endpoint devices, and back-end services.
• Strong knowledge of VOIP technologies and protocols, including SIP and RTP, and familiarity with H.323.
• Experience implementing SIP for call setup, routing, and teardown, and handling RTP media streams for real-time voice transport.
• Working knowledge of SNMP, including MIBs, OIDs, traps, and polling, for device monitoring and management.
• Experience designing and integrating web services using REST, JSON, WebSocket, or SOAP.
• Strong understanding of networking fundamentals, including TCP, UDP, NAT, and Quality of Service (QoS).
• Experience working in both Linux and Windows environments, with a preference for Linux.
