IMS Cloud Architect (m/f/d)

About us:
Committed to building the next generation of 100% software-based mobile networks, ng-voice is creating innovative mobile infrastructure solutions and making them accessible for operators and enterprises that want to deploy future-proof networks. 

We are looking for an IMS Cloud Architect to join our team.

Tasks:
What you'll do

• Design and own the cloud-native architecture of our Kubernetes-based telecom platform across public cloud and on-prem environments.
• Ensure cloud readiness of product features – review and validate infrastructure, networking, security, observability, and automation impacts early in the lifecycle.
• Drive the cloud platform roadmap – identify gaps, raise enhancements, and improve scalability, resilience, and operability based on real-world deployments.
• Define customer deployment architectures – own the cloud and infrastructure sections of high-level designs, including HA/DR, scaling, and upgrade strategies.
• Support customer engagements – lead technical discussions on cloud architecture, sizing, resilience, and operational models during pre- and post-sales phases.
• Champion operability – ensure features ship with monitoring, logging, alerting, and clear operational guidance.
• Work cross-functionally – collaborate closely with product, engineering, deployment, and customer-facing teams to avoid late-stage infrastructure surprises.

Requirements:
Our ideal new colleague should have

• 5–10 years of experience in cloud or platform architecture for distributed systems.
• Strong hands-on experience with Kubernetes in production environments (Helm, networking, upgrades, security).
• Solid understanding of Kubernetes networking concepts (ingress/egress, CNI, network policies; multi-network setups a plus).
• Experience with observability stacks (metrics, logs, tracing, alerting).
• Hands-on experience with public cloud Kubernetes distributions such as GKE and/or AWS EKS.
• Comfortable reading and reviewing YAML / Helm configurations and translating requirements into actionable work.
• Pragmatic mindset – able to balance architectural best practices with delivery and customer realities.
• Clear communicator, comfortable working with engineers and customer technical teams.

Nice-to-have extras

• Experience running telecom or real-time workloads (IMS, VoLTE, SBC, signaling systems).Designed highly available or geo-redundant Kubernetes platforms.
• Infrastructure-as-Code or GitOps experience.
• Background in building telecom network functions on kubernetes platforms
