We are building a world-class Customer Engineering team that sits at the intersection of technical expertise, deployment excellence, and Customer success / Service adoption. If you love solving complex network problems, thrive in direct customer relationships, and are equally comfortable owning a support ticket, planning & deploying integration projects and leading a Q  - we want to hear from you.

In this role, handling tickets is not a side task - it is the engine. Every ticket is a window into how a customer is actually experiencing our solutions. Resolving them with rigor and speed builds trust, drives successful deployments, and defines what customer success means for each client - because success is not a template; it is what the customer needs it to be.

• Own incoming customer requests end-to-end - triage with urgency/priority, document thoroughly, and escalate fast when needed, never let tickets go stale.
• Troubleshoot and resolve complex technical issues across Meraki, Fortinet, HP Aruba, Cisco WLC, and Zscaler environments and more to come – digging into root cause, not just symptoms.
• Use every resolved ticket as a learning artifact: update the knowledge base, flag recurring patterns, and turn individual fixes into systemic improvements.
• Treat ticket quality as a proxy for customer health – a well-handled issue strengthens the relationship; a poorly handled one erodes it.

• Lead technical onboarding: configure, deploy, and validate our solutions in live customer environments – on‑site or remote.
• Convert recurring support patterns into proactive deployment improvements so the same issue never becomes a ticket twice.
• Stay current with emerging network and security technologies – and share what you learn with the team.
• Collaborate cross‑functionally with Product, Engineering, and Sales to close the loop on issues and drive continuous improvement.

• Build trusted advisor relationships with your assigned enterprise clients – you are their go‑to, across finance, retail, healthcare, and transport.
• Lead recurring reviews (Q /E ): present health scores, surface insights from ticket data, and align on roadmap priorities.
• Proactively identify risks and blockers before they become escalations – using data, pattern recognition, and customer knowledge.
• Deliver structured voice‑of‑customer feedback that directly influences our roadmap.

• 3 years minimum in a support role
• CP/IP fundamentals: OSI, routing, DNS, NAT
• VPN Troubleshooting (IPSEC, GRE)
• Root cause analysis (RCA) methodology
• Ticketing systems and structured documentation (ITIL Standard)
• Technical onboarding and customer training
• Fluent or native English (client‑facing level)

• Zero Trust / ZTNA concepts
• Experience running QBRs / EBRs
• Cross‑functional collaboration (PS, Support, Product)
• Traffic analysis & network monitoring
• German fluency (client‑facing)
• Expertise on different cybersecurity vendor

• Wireshark / HAR capture analysis
• Basic scripting (Python, bash) for automation or log parsing
• French or Spanish fluency

• A team player above all – a learner, a can‑do & accountability attitude
• Comfortable with role fluidity: in the same week, you might close a P1 ticket, run a…
