ABOUT THE ROLE

We are looking for a Mid-level Site Reliability Engineer (SRE) to help transition our incident management from reactive firefighting to proactive reliability engineering.

You will play a key role in improving observability, reducing incident frequency, and helping engineering teams understand how systems behave in production.

KEY RESPONSIBILITIES

              •            Own and improve monitoring, alerting, and observability for production systems

              •            Lead or contribute to incident investigations and postmortems

              •            Design alerts based on symptoms and user impact rather than infrastructure noise

              •            Use observability tools to analyze performance, errors, and traffic patterns

              •            Identify reliability risks before they turn into incidents

              •            Improve run books, on-call processes, and operational readiness

              •            Work closely with software teams to improve system resilience

              •            Automate repetitive operational tasks

REQUIRED SKILLS AND EXPERIENCE

              •            Strong Linux experience in production environments

              •            Hands-on experience with at least one major cloud provider (AWS preferred)

              •            Solid understanding of monitoring, alerting, and incident response

              •            Experience with observability tools (New Relic, Prometheus, Datadog, etc.)

              •            Scripting or automation experience (Bash, Python, or similar)

              •            Understanding of distributed systems fundamentals

              •            Comfortable participating in on-call rotations

NICE TO HAVE

              •            Experience with Infrastructure as Code (Terraform, CloudFormation, etc.)

              •            Experience with containers or orchestration (ECS, Kubernetes, Docker)

              •            Experience supporting PHP, Node.js, or similar application stacks

              •            Familiarity with SRE concepts such as SLIs, SLOs, and error budgets

WHAT SUCCESS LOOKS LIKE

              •            Reduced number of repeat incidents

              •            Clear and actionable alerts

              •            Faster detection and resolution of incidents

              •            Improved visibility into system health and performance

              •            Engineering teams that trust monitoring data

WHY JOIN US

              •            Real influence over how reliability is implemented across the company

              •            Work on systems operating at meaningful scale

              •            Opportunity to grow into Senior SRE or SRE Tech Lead roles

              •            Strong focus on engineering quality rather than ticket volume

Flexible working arrangements, with the ability to work both from our Sofia office and from home in a hybrid working model also available!
