## Description (the employer's text)

### About us

You'll work in a global team with colleagues in APAC, EMEA, and the Americas, handle scheduled after-hours maintenance windows, and take part in the on-call rotation from time to time.

The role is located in Europe.

### Tasks

- Own customer support tickets from first response to closure, through Jira Service Management, email, phone, and chat.
- Troubleshoot L1/L2 issues across Linux, IMS, SIP, Diameter, Kubernetes, and networking, using logs, traces, packet captures, and monitoring data.
- Keep customers updated clearly and regularly, with written updates their technical teams can act on.
- Escalate to senior engineers, Engineering, or Cloud with enough evidence (traces, logs, timeline, impact, steps already taken) that they can act without asking again.
- Join major incidents: run investigation tasks, gather data, and report findings to the incident lead.
- Plan and run software upgrades and maintenance windows for customer deployments, including pre-checks, execution, validation, and rollback readiness.
- Monitor selected customer environments, respond to alerts, and flag risks before they become incidents.
- Provide input for RCAs and write up findings from resolved issues.
- Improve runbooks, SOPs, knowledge base articles, and monitoring and alerting.
- Hand over reliably across regions: open tickets, ongoing incidents, maintenance, and customer commitments.
- Keep ticket quality, SLA compliance, and follow-up high across the queue.
### Requirements

- Hands-on Linux administration and troubleshooting experience.
- Solid networking knowledge: routing, switching, firewalls, NAT, DNS, and load balancing.
- Working knowledge of SIP and Diameter, including reading call flows and signaling traces.
- Experience with IMS or VoIP/telecom core environments.
- Packet-level troubleshooting with Wireshark and tcpdump.
- Experience supporting technical customers (operator or enterprise engineering teams) in a ticket-driven, SLA-based environment.
- Clear written and spoken communication, and the ability to stay calm and structured under pressure.
- Willingness to work scheduled after-hours maintenance windows and take part in the on-call rotation from time to time.
- Fluent English.
Nice to have:

- Kubernetes operations, ideally on AWS (EKS) or another public cloud.
- Helm and container networking (Multus, Longhorn, or similar).
- Prometheus, Grafana, Alertmanager, Loki, or similar observability tools.
- Hands-on experience with IMS components (P-CSCF, S-CSCF, I-CSCF, DRA, HSS, PCRF/PCF, MMTEL).
- Experience with VoLTE, VoWiFi, EPC, or 5G.
- Experience running upgrades or maintenance on production telecom systems.
- Jira Service Management and Confluence.
### Benefits

- Work on live IMS and cloud-native telecom networks across multiple continents.
- Build real depth in voice core, Kubernetes, and cloud operations in the same job.
- Learn from senior engineers through real investigations, with a clear path to senior and lead roles.
- Flexible, hybrid remote culture: we care about ownership and results, not where you sit.
- We value experience and knowledge over formal degrees.
- A diverse team in a traditionally not very diverse industry.
- Mobility, fitness, language class, and wellness benefits, plus a home-office budget (for full-time employees).
