The posting

Your mission

At Telio, we build technology that reconnects people.

Our systems enable hundreds of thousands of inmates to stay connected with their families and loved ones. We believe correctional facilities should not only serve as punishment, but also as an opportunity for rehabilitation and a second chance. Through secure communication technology, digital services, and modern software platforms, we elevate the professional and human standards of correctional institutions and other regulated environments (e.g., clinics and state institutions).

This is a mission-critical internal product environment where reliability, security, and engineering excellence directly impact real lives.

We are looking for a skilled Application Reliability Engineer to support the reliability, monitoring, and automation of business-critical applications across hybrid Azure and on-premises environments. You will work closely with development, IT operations, and infrastructure teams to detect issues early, improve observability, reduce alert noise, support incident resolution, and prevent recurring problems through automation and a reliability-first mindset.

  • Support incident handling, root cause analysis, and long-term reliability improvements.
  • Operate and improve applications and infrastructure in Microsoft Azure, on-premises, Kubernetes, and GitOps-based environments.
  • Collaborate with development, IT, and infrastructure teams to reduce manual work and improve service stability.

Required Qualifications, Experience & Competencies

Professional Experience & Skills

  • 3+ years’ experience in system operations, application support, or site reliability engineering.
  • Experience with Linux and Windows servers, scripting, monitoring or observability tools, and incident management.
  • Hands-on knowledge of Kubernetes, container orchestration, GitOps practices, and hybrid cloud environments.
  • Basic understanding of .NET/C#, web applications, web services, relational databases, and infrastructure operations.
  • Analytical mindset, strong problem-solving skills, attention to detail, and communicational level English.
  • Advantage: Infrastructure as Code, CI/CD pipelines, SLI/SLO concepts, escalation tooling, container security, networking fundamentals, REST/SOAP APIs, or message queues.

Why us?

We are offering

  • Professional challenges, inspiring, diverse tasks
  • Learning path on new technologies
  • Multiculture environment
  • Flexible working hours and home office days (2 days/week)
  • Relaxed atmosphere, steady, supportive international team

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.
