What is a VoIP engineer?

A VoIP engineer oversees the installation and maintenance of VoIP, or voice over internet protocol, telephony systems. VoIP is a system through which parties can communicate over the internet, as opposed to through a traditional telephone system. Engineers are usually employed by a single company to manage their in-house network. As a VoIP engineer, your responsibilities include determining the company’s needs, developing a network with the proper hardware to fit those needs, and monitoring the system to ensure voice communication is functioning correctly. You may need an associate’s degree in this career, but many employers will accept a high school diploma and an appropriate certification from a company like Cisco. You need extensive computer and analytical skills to succeed as a VoIP engineer.

What are some common challenges a VoIP engineer faces when integrating new communication systems within an existing IT infrastructure?

VoIP Engineers often encounter challenges such as ensuring seamless compatibility between new VoIP solutions and legacy systems, managing network bandwidth to prevent call quality issues, and securing voice data against potential cyber threats. Effective troubleshooting and collaboration with both IT and network security teams are essential to resolve these issues quickly. Additionally, VoIP Engineers must stay updated on evolving protocols and compliance standards to ensure smooth and secure deployments.

What are the key skills and qualifications needed to thrive as a VoIP engineer, and why are they important?

To thrive as a VoIP Engineer, you need a strong understanding of networking fundamentals, VoIP protocols (such as SIP and RTP), and hands-on experience with VoIP systems, typically supported by a degree in computer science or related field. Familiarity with tools like Wireshark, PBX platforms (e.g., Cisco, Asterisk), and relevant certifications such as CCNA or CCNP Voice is highly valued. Strong problem-solving abilities, attention to detail, and effective communication are essential soft skills for diagnosing issues and collaborating with cross-functional teams. These skills and qualifications are critical to ensuring reliable, high-quality voice communication services and rapid resolution of technical problems in business environments.

What is the difference between Voip Engineer vs Network Engineer?

AspectVoip EngineerNetwork Engineer
CertificationsCCNA, CCNP, Cisco Voice certificationsCCNA, CCNP, Cisco, CompTIA Network+
Work EnvironmentTelecommunications, VoIP systems, cloud platformsNetworking infrastructure, data centers, enterprise networks
Industry UsageTelecom providers, IT service companiesIT departments, telecom, enterprise organizations

Voip Engineers focus specifically on designing, implementing, and maintaining VoIP communication systems, while Network Engineers handle broader network infrastructure including LAN, WAN, and security. Both roles require networking certifications and often work in similar environments, but their core responsibilities differ in scope and specialization.

Are Voip engineers in demand?

VoIP engineers are in demand due to the growing reliance on internet-based communication systems in businesses. They are needed to design, implement, and maintain VoIP solutions, often requiring knowledge of networking, protocols, and certifications like CCNA or CCNP. The role offers good job prospects in IT and telecommunications sectors.

How much do Voip engineers make in the US?

VoIP engineers in the US typically earn between $70,000 and $120,000 annually, depending on experience, certifications, and location. Entry-level positions may start around $60,000, while experienced professionals with specialized skills can earn over $130,000. Knowledge of networking, SIP protocols, and VoIP systems is essential for higher earning potential.

Job description

Knightscope Senior Audio/Video Engineer

Knightscope is a security technology company building the nation's first Autonomous Security Force with autonomous machines, AI-driven software, and elite security professionals operating as one integrated managed service. The Company is on a mission to make the United States of America the safest country in the world. One Team. One Force.

Job Description

Knightscope is seeking two Senior Audio/Video Engineers to own the real-time audio and video infrastructure across the ICM and Signals platforms. These engineers will be responsible for the full A/V stack from WebRTC ingest and GStreamer pipeline architecture to low-latency audio processing and multi-stream rendering.

Key Responsibilities

  • Design, build, and maintain the end-to-end real-time video pipeline: WebRTC/RTSP/RTMP ingest, hardware-accelerated transcoding, and simultaneous multi-stream rendering for up to 10 concurrent robot video feeds.
  • Architect and optimize GStreamer-based multi-branch pipelines for video capture, processing, recording, and cloud upload (S3) including codec selection, pad/cap negotiation, and plugin development.
  • Own the full audio subsystem: real-time two-way audio, SIP/VoIP integration (pjsip/Asterisk), text-to-speech (AWS Polly), and talk-down functionality with a sub-200ms end-to-end round-trip latency target.
  • Implement and optimize WebRTC signaling, ICE, DTLS-SRTP, and media server components for reliable low-latency communication across distributed robot deployments.
  • Profile, debug, and tune A/V pipeline performance for low latency, high throughput, and resilience under concurrent multi-robot load and variable network conditions.
  • Build Make-a-Clip functionality enabling operators to extract, annotate, and store video segments from live and recorded feeds.
  • Define and maintain A/V API contracts in collaboration with ICM and Signals platform engineers; contribute to code reviews, technical documentation, and on-call runbooks.
  • Mentor junior engineers and contribute to architectural decisions across the A/V stack.

Required Qualifications

  • 7-10 years of software engineering experience specializing in real-time audio and video systems in production environments.
  • Deep expertise in WebRTC including signaling protocols, ICE/STUN/TURN, DTLS-SRTP, RTP/RTCP, and media server architecture (Janus, mediasoup, or equivalent).
  • Strong hands-on proficiency with GStreamer at the developer level: building and debugging complex multi-branch media pipelines, working with elements, pads, caps, and custom plugins.
  • Proficiency in C/C++ (C++11/14/17) for performance-critical media and networking code; Python for tooling and automation.
  • Solid experience with SIP/VoIP protocols and stacks (pjsip, Asterisk, or equivalent) and low-latency audio processing.
  • Strong understanding of audio/video codecs (H.264/H.265, VP9, AAC, Opus) and streaming protocols (RTSP, RTMP, HLS, RTP).
  • Experience with AWS media services (S3, Kinesis Video Streams, Polly, or equivalent) and cloud-based media pipeline architectures.
  • Familiarity with hardware-accelerated video processing (NVIDIA NVENC/NVDEC, V4L2, or equivalent) is a strong plus.
  • BS in Computer Science, Electrical Engineering, or equivalent professional experience.

Compensation & Benefits

  • Base Salary: $155,000 - $210,000 each (DOE)
  • Equity: Stock options
  • Benefits: Medical, dental, vision, 401(k), paid time off
  • Location Requirement: Full-time, on-site at Sunnyvale HQ
