We’re hiring a senior infrastructure engineer to help operate, secure, and improve a production cloud-based voice communications platform.

This role is hands-on and reliability-focused: you’ll troubleshoot live voice traffic issues, maintain high-availability systems, improve monitoring and automation, and help execute safe production changes.

The platform runs primarily on AWS and supports real-time communications workloads where uptime, latency, call quality, and operational discipline matter.

You should be comfortable working across Linux systems, cloud infrastructure, SIP-based services, databases, message queues, monitoring tools, DNS, networking, and automation.

Responsibilities

Operate and improve production and staging infrastructure for a cloud-hosted VoIP/UC platform.
Investigate and resolve issues involving SIP signaling, RTP/media, registrations, call routing, NAT traversal, presence/status indicators, voicemail notifications, provisioning, and customer-impacting call behavior.
Manage AWS-based infrastructure including compute, networking, DNS, IAM, storage, load balancing, monitoring, automation, and environment separation.
Support high-availability and disaster-recovery procedures across application, media, database, messaging, DNS, and networking layers.
Perform safe production maintenance, capacity planning, instance sizing, patching, upgrades, and controlled rollouts.
Build and maintain automation using Python, Bash, AWS tooling, and infrastructure-as-code practices.
Use logs, metrics, packet captures, call traces, monitoring dashboards, and CDR-style records to diagnose issues end-to-end.
Maintain and improve observability, alerting, incident response workflows, and operational dashboards.
Support customer provisioning and migration workflows for IP phones, softphones, web clients, and related voice services.
Collaborate with engineering, support, and leadership to prioritize reliability work, customer-impacting issues, and infrastructure improvements.
Create and maintain clear runbooks, standard operating procedures, and post-incident learnings.
Manage incidents/responses and planned maintenance windows when needed.

Required Experience

5+ years in infrastructure, systems engineering, network engineering, SRE, DevOps, or telecom operations.
3+ years operating production VoIP, SIP, UCaaS, PBX, carrier, contact-center, or real-time communications infrastructure.
Strong Linux administration skills in production environments.
Strong AWS experience, especially EC2, VPC networking, Route 53, IAM, load balancing, storage, monitoring, and automation.
Strong understanding of SIP, RTP, DNS/SRV, NAT traversal, TLS, WebRTC concepts, packet captures, and call-flow troubleshooting.
Experience with distributed systems, clustered services, message queues, replicated databases, and failover patterns.
Strong scripting ability with Python and Bash.
Experience with monitoring/logging systems and operational debugging using logs, metrics, traces, and packet captures.
Comfortable performing production changes with careful planning, validation, rollback thinking, and written procedures.
Strong written English and clear async communication.

The ideal candidate is a senior, hands-on infrastructure engineer with real production VoIP experience. They can debug from the customer report down through signaling, media, application logs, cloud networking, and system health. They are careful around production, pragmatic about automation, and comfortable documenting decisions so the platform becomes more reliable over time.

This is not a generic DevOps role. We need someone who understands that voice infrastructure has sharp edges: latency, packet loss, NAT, failover behavior, endpoint quirks, DNS behavior, and customer-visible impact all matter.

Nice To Have

Experience with open-source SIP proxies, media servers, or telecom application platforms.
Experience with clustered NoSQL databases, message brokers, or event-driven systems.
Experience with infrastructure-as-code, CI/CD, GitHub Actions, CloudFormation, Terraform, or similar tooling.
Experience with VPNs, firewalls, IPsec, WireGuard, or hybrid cloud networking.
Experience with VoIP monitoring tools, SIP capture platforms, or packet-analysis workflows.
Experience supporting phone provisioning, zero-touch provisioning, carrier integrations, fax, STIR/SHAKEN, or emergency calling.
