Vacancies

Head of IT

  • Income level not specified
  • Astana

We need a specialist with 5+ years of experience in IT infrastructure, a deep understanding of networks, servers, IP telephony, and experience in forming or rebuilding an IT team, including in a remote format. It is important to have a systematic mindset, calmness in incidents, focus on results and willingness to be responsible for the technical outcome and order in the infrastructure.

This is not a "hands-off manager" position. This is a role for a person who designed networks himself, raised telephony, dealt with servers — and now knows how to build a team's system work, including remotely.

The format of the work

  • Start: full-time presence in the office in Karaganda for at least 1-2 months (onboarding, auditing, immersion in processes and the team).
  • Then: (if you do not live in Karaganda) switch to the remote management format from another city with regular visits to the office (at least once a month).

Team: up to 5 technical specialists + dedicated GPH specialists (DevOps, Telephony specialist, Network Specialist).

Tasks: organization of the Service Desk, uninterrupted operation of the server infrastructure, IP telephony, implementation of AI call centers.

What will you do?

  • Fully responsible for the technical result of the IT department.
  • To form and rebuild the IT department for real tasks (part of the team is local, part is distributed).
  • Strictly prioritize tasks and manage the team's workload, including in a remote format (online planning, reporting).
  • Personally participate in complex technical solutions and architecture.
  • Be the 3rd line in incidents where "everything has already been tried."
  • Design and monitor the implementation of AI solutions, IP telephony, server and network solutions.
  • To bring order to the infrastructure and processes systematically, to build stable processes that work even without the physical presence of the head.

Mandatory experience

  • 5+ years in infrastructure IT.
  • Real-world experience in forming or rebuilding an IT team.
  • Deep understanding of networks: TCP/IP, VLAN, routing, VPN, NAT.
  • Practical experience with IP telephony: SIP, VoIP, Asterisk/FreePBX or analogues.
  • Server infrastructure: Windows Server and/or Linux, virtualization, fault tolerance.
  • Experience in implementing solutions from external clients.
  • Willingness to be responsible for the outcome.
  • Experience in remote management of a distributed team, or at least the willingness to quickly integrate into such a format.

We definitely won't be suitable if you

  • They were in charge, but they didn't get involved in technology.
  • You get lost in accidents.
  • You don't know how to say no to unrealistic deadlines.
  • You ignore the documentation.
  • They are used to a sterile environment without chaos and are not ready to restore order in stages.
  • We are not ready to combine the start period in the office and further remote format with periodic business trips.

That would be a plus

  • Call center projects.
  • Integration of AI/bots/voice assistants.
  • Monitoring and logging.
  • Work on SLA and service metrics.

Personal qualities

  • Systems thinking.
  • Calmness in incidents.
  • Demanding of yourself and your team.
  • Result orientation.
  • The ability to build transparent processes and communications in a distributed team (online rituals, incident response rules, reporting).

The first months

In the office, with the transfer to the remote

  • Audit of infrastructure and projects.
  • Division of responsibility within the team.
  • Restoring order to tasks and processes.
  • Reducing recurring technical issues.
  • Setting up the remote control format: regulations, communication channels, dashboards, reporting, on-call processes.

This is a role for a strong technical leader, not for an "IT coordinator" who appears in the office once a month and "looks at reports."
