● Hands-on automation experience using Ansible, Puppet, Chef, or similar.

● Proficiency in scripting (Bash, Python, Perl).

● Strong troubleshooting skills in multi-tier, distributed, and hybrid environments.

● Experience with monitoring and observability (Nagios, Zabbix, Prometheus, Grafana, ELK, Splunk).

● Knowledge of virtualization (VMware, KVM) and Linux on cloud platforms (AWS, Azure, GCP).

● Familiarity with ITIL processes and managed services delivery.

● Excellent communication and customer-handling skills for escalations and service reviews.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
