🔎 We’re looking for a mid to senior-level VOIP & Infrastructure Engineer to help us build, maintain, and evolve our internal telephony infrastructure. This role sits at the intersection of VOIP systems and infrastructure engineering - ideal for someone who enjoys working across systems and digging into both application and platform layers.

Responsibilities

• Operate and improve our VOIP infrastructure, including Asterisk-based systems, 3CX, and supporting services.
• Maintain and evolve the underlying infrastructure: Linux servers, virtual machines, Docker containers, network config, and monitoring.
• Design and implement scalable, resilient solutions for call routing, recording, monitoring, and integrations.
• Troubleshoot complex VOIP and infrastructure issues across layers (SIP, RTP, NAT, system performance, disk, etc.).
• Collaborate with the VOIP team to automate deployment, configuration, and monitoring of VOIP components.
• Own or contribute to infrastructure reliability, backup strategies, system upgrades, and security hardening.

Requirements

• 5+ years of professional experience in systems engineering, infrastructure operations, VOIP engineering, or a similar technical role.
• Strong experience with either:
  • VOIP systems (e.g., Asterisk, FreePBX, FreeSWITCH, 3CX, Kamailio, SIP protocols, RTP, dial plans), OR
  • Infrastructure engineering (Linux systems, virtualization, Proxmox, Docker, CI/CD, scripting, monitoring).
• Proven ability to operate and troubleshoot production systems, including performance issues, outages, and cross-layer failures.
• Strong foundation in networking, particularly where it intersects with VOIP (SIP, RTP, NAT traversal, QoS, firewalls, etc.).
• Prior experience working in environments where engineers own systems end-to-end is strongly preferred.
• Comfort working in a production environment with systems you own end-to-end.
• Solid troubleshooting skills and a deep interest in how systems work.
• Experience with networking concepts, especially as they relate to VOIP (firewalls, NAT, QoS, etc.).
• Experience with monitoring/observability stacks (Prometheus, Grafana, Zabbix, etc.).
• Business level proficiency in English or above (equivalent to B2 or above in CEFR)

Nice to have

• Familiarity with automation tools (Ansible, Terraform, etc.).
• Exposure to telephony integrations (e.g., CRMs, Zendesk, analytics tools).
• Experience with designing telephony platform architectures.
• Exposure to observability stacks (e.g., Prometheus, Grafana, ELK) and proactive monitoring strategies.
• Experience with system automation, scripting (e.g., Bash, Python), or configuration management tools.
