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