Job description

At Weave (NYSE: WEAV), we're on a mission to elevate the patient experience by giving healthcare practices the tools they need to run more efficiently and meaningfully connect with their patients. With 40,000+ customers and growing, Weave's all-in-one platform supports every interaction-from scheduling and payments to communication and reviews-making it easier for healthcare professionals to focus on what matters most: patient care.
Weave is looking for a VoIP Engineer with a strong background in modern communication tools and cloud technologies to help maintain and optimize our distributed, cloud-based voice platform. In this role, you'll ensure our communication systems are robust, efficient, scalable, and observable working hands-on with SIP/RTP infrastructure and core components like Kamailio, RTPengine, FreeSWITCH, and Homer/HEPIC. You'll collaborate cross-functionally with engineering and operations teams to improve reliability, performance, and customer call quality while shipping improvements through DevOps best practices.
  • This position can be remote, in office, or hybrid
  • Reports to: Engineering Manager
What You Will Own
  • Grow and manage a distributed cloud-based VoIP platform
  • Optimize and troubleshoot FreeSWITCH and Kamailio configurations for performance, resiliency, and reliability
  • Design, build, test, deploy, and maintain services that support the voice platform
  • Monitor and analyze VoIP network performance, identify areas for improvement, and implement solutions to enhance quality and efficiency
  • Troubleshoot and resolve VoIP-related issues including call quality problems, signaling/connectivity issues, and system outages
  • Develop Golang-based microservices and containers that support the voice ecosystem
  • Deploy and operate services in Kubernetes environments
  • Maintain and configure Kamailio and FreeSWITCH instances
  • Implement and improve observability for SIP/RTP flows using HEP/Homer and telemetry (metrics/logs/traces) to accelerate incident response and root-cause analysis
  • Partner with SRE/Platform teams to improve CI/CD, infrastructure-as-code, and reliability practices (e.g., automated rollouts, canarying, and repeatable environments)
What You Will Need to Accomplish the Job
  • Previous experience working as a VoIP network engineer
  • Experience with VoIP applications such as Kamailio, OpenSIPS, FreeSWITCH, RTPengine, and Asterisk
  • Experience with troubleshooting tools such as Wireshark, sngrep, and Homer
  • Deep understanding of TCP/IP networks, firewalls, and related protocols (SIP, RTP, RTCP, TLS, ICE, STUN, TURN, WebRTC)
  • Programming experience with a major language such as Go, Java, or C
  • Experience with scripting languages such as Python, Bash, and LUA
  • Experience with DevOps tools for cloud infrastructure management and automation such as Terraform and Ansible
  • Flexibility and adaptability in learning new technologies and tools
  • Strong written, oral, and interpersonal communication skills
  • Highly self-motivated and directed
  • Keen attention to detail
  • Experience operating production services in a major cloud environment (Google Cloud preferred), including networking concepts such as VPCs, load balancing, service discovery, and IAM/security fundamentals
  • Comfort participating in on-call rotations and driving incident remediation through postmortems and follow-up engineering work

What Will Make Us Love You
  • 5+ years of experience designing and supporting large scale VoIP networks
  • Certifications in Kamailio or OpenSIPS
  • Hands-on experience with Kubernetes operations (deployments, services/ingress, Helm/Kustomize, autoscaling, and debugging)
  • Experience designing or improving call-quality tooling (MOS/RTCP analytics, jitter/loss monitoring, SBC/edge routing strategies, or capacity planning)
