VoIP DevOps Engineer

Staff / Senior DevOps Engineer – Telecommunications Platform (FreeSWITCH / Kamailio / Kubernetes)

Location: Remote (Eastern Europe Preferred – Ukraine, Serbia, Romania, Poland, Bulgaria)

Compensation: USD $70,000–100,000 (depending on experience) + Equity

Build the Future of AI-Powered Communications

Peerlogic is building the next generation AI communications platform for healthcare.

Today, millions of businesses still rely on legacy, stand-alone VoIP systems. We’re replacing them with a fully integrated, cloud-native communications platform built on FreeSWITCH, Kamailio, Kubernetes, and AI.

We’re looking for a Staff or Senior DevOps Engineer who enjoys building highly available infrastructure at scale. While telecommunications experience is important, this is fundamentally an infrastructure engineering role focused on automation, reliability, scalability, and cloud-native architecture.

This is not a PBX administrator position.

You’ll help build the platform that powers AI voice agents, intelligent call routing, messaging, analytics, and communications for thousands of healthcare organizations.

What You’ll Build

You’ll design, deploy, and operate a modern telecommunications platform that includes:

• FreeSWITCH clusters
• Kamailio SIP infrastructure
• Kubernetes orchestration
• Telnyx carrier integrations
• AI voice services
• Provisioning APIs
• Call routing services
• Voice recording
• Monitoring and observability
• High-availability architecture
• Disaster recovery
• CI/CD pipelines and infrastructure automation

You’ll work closely with engineering leadership to build infrastructure that is secure, resilient, automated, and capable of supporting rapid growth.

Responsibilities

• Design and operate highly available Kubernetes infrastructure
• Build and maintain FreeSWITCH and Kamailio production environments
• Automate infrastructure provisioning and deployments
• Develop CI/CD pipelines and Infrastructure as Code
• Design secure, scalable SIP infrastructure
• Integrate with telecom carriers including Telnyx
• Optimize system performance, call quality, and platform reliability
• Implement monitoring, logging, alerting, and observability
• Develop provisioning APIs and operational tooling
• Troubleshoot complex Linux, networking, SIP, and RTP issues
• Collaborate with AI engineers to integrate voice intelligence services
• Improve platform scalability, resiliency, and security

What We’re Looking ForRequired Experience

• 7+ years of DevOps, Platform Engineering, Site Reliability Engineering, or Infrastructure Engineering experience
• Production experience with Kubernetes and Docker
• Strong Linux systems administration
• Experience designing highly available distributed systems
• Strong networking knowledge (TCP/UDP, DNS, NAT, TLS, firewalls, load balancing)
• Experience building CI/CD pipelines and infrastructure automation
• Experience with Infrastructure as Code (Terraform preferred)
• Experience with monitoring and observability platforms
• Strong written and spoken English

Telecommunications Experience

Candidates should also have experience with several of the following:

• FreeSWITCH
• Kamailio or OpenSIPS
• SIP
• RTP
• Carrier integrations
• VoIP or UCaaS platforms
• CPaaS infrastructure

Nice to Have

• Google Cloud Platform or AWS
• PostgreSQL
• Redis
• Go, Python, or Node.js
• Helm
• Prometheus
• Grafana
• Loki
• OpenTelemetry
• Homer SIP Capture
• Experience building CPaaS or UCaaS platforms
• AI voice or speech-processing systems
• Telnyx integrations

What Success Looks Like

Within your first year, you’ll help us:

• Launch a production-ready telecommunications platform
• Successfully migrate customers from legacy VoIP infrastructure
• Build fully automated deployment and provisioning pipelines
• Deliver carrier-grade reliability and uptime
• Scale the platform to support tens of thousands of concurrent users
• Enable AI-powered communications across our product suite

Who You Are

You enjoy building platforms—not simply maintaining servers.

You think like an owner, automate repetitive work, and enjoy solving difficult infrastructure problems.

You’re equally comfortable discussing Kubernetes architecture, Linux performance tuning, distributed systems, and SIP call flows.

You thrive in fast-moving startups where you’ll have significant ownership and influence over technical direction.

Why Peerlogic?

You’ll join a small, highly technical engineering team building one of the most advanced AI communications platforms in healthcare.

You’ll help shape the future architecture of the platform while working with modern cloud infrastructure, telecommunications technologies, and AI.

This is an opportunity to build something from the ground up—not inherit someone else’s legacy infrastructure.

How to Apply

Please include:

• A résumé or LinkedIn profile
• A brief description of the largest production infrastructure you’ve built or managed
• Your experience with Kubernetes, Linux, and infrastructure automation
• Any experience with FreeSWITCH, Kamailio, OpenSIPS, SIP, or telecommunications platforms
• Your preferred annual compensation (USD)

Bonus

Tell us about the most challenging production outage you’ve diagnosed and resolved. What happened, how did you identify the root cause, and what changes did you implement to prevent it from happening again?
