About the role

  • Serve as the primary escalation point for L1–L2 on severe/complex issues (discovery failures, upgrade problems, parsing defects, path-lookup anomalies, API/integration errors).
  • Proactive and timely communication with customers and internal teams.
  • Triaging incoming issues and leading deep-dive troubleshooting across Linux, networking, and APIs.
  • In-depth debugging/troubleshooting and solving customer-reported issues, including Linux logs analysis for all services, service log troubleshooting, and resolving parsing and mapping issues from CLI outputs.
  • Path lookup troubleshooting: Investigate how traffic flows through customer infrastructure, analyze routing decisions, and validate protocol behavior (BGP, OSPF, MPLS, EVPN/VXLAN, ACLs, QoS). This requires strong networking knowledge and the ability to interpret complex topologies, at least on CCNA level.
  • De-escalating situations where customers have become frustrated or upset.
  • Escalating confirmed product bugs to engineering via internal bug reports.
  • Look for ways to improve our customer communication and support processes.
  • Help create and maintain documentation and knowledge base.
  • Remote real-time debugging sessions with customers.
  • Own and evolve support tooling - design, code reviews, documentation, and adoption.
  • Mentor L1–L2 engineers and contribute to onboarding.
  • Actively participating on increasing team effectiveness, as well as building roadmap for the support team each 6/12/24 months.

  • Virtualization/Cloud: Hypervisors (KVM/ESXi/Proxmox) plus AWS/Azure networking basics.
  • Scripting/Automation: Practical Python for support tools and data wrangling (REST/JSON, log parsing, CLI automation). Git workflows; Markdown; code reviews.
  • Customer interaction experience with strong written and oral communication skills in English.
  • Ability to keep calm under pressure and de-escalate tense situations.
