The Challenge Ahead:

With the newly built, fully Infrastructure-as-Code (IaC) platform in place, the Infrastructure Team is now focused on operating, improving, and scaling it. The challenge ahead lies in hardening reliability, enhancing observability, and refining automation to remove remaining manual gaps. While best practices are already embedded, there’s still room to drive maturity. We’re looking for an engineer who would thrive in continuous improvement, can spot weaknesses, and enjoy building infrastructure that’s both robust and elegant.

In addition, we are increasingly investing in the scalability and performance of our data layer. As our platform grows, we need stronger expertise in database operations — from scaling core database systems, improving reliability under load, and optimizing query performance. Supporting teams in diagnosing slow queries and designing resilient database architectures is becoming a key part of our infrastructure roadmap.

What you will do:

Design, build, harden, and maintain the core infrastructure used by all of CloudTalk’s engineering teams running in AWS
Help developers with finding and optimising critical database queries and tweak database servers
Automate every aspect of our infrastructure to remove any human intervention as much as possible
Design and deploy new services into Kubernetes cluster (AWS EKS)
Participate in team brainstorming sessions to define future of CloudTalk’s infrastructure
Implement security policies across cloud-based infrastructure
Optimize existing services to achieve better performance
Develop effective tooling, alerts, and response to both identify and address reliability risks
Drive and promote protocols on production readiness and operational excellence
Partner with product engineering teams to debug production outages and carry out action items to improve the reliability of those systems
Participate in design reviews and production reviews for new features, products, or pieces of infrastructure
Plan for the growth of CloudTalk’s infrastructure

What we are looking for:

Knowledge of AWS
Knowledge of Kubernetes

Experience with optimising database systems (MariaDB, MongoDB, PostgreSQL, ...)
Knowledge of Bash scripting
Managing 24/7 production infrastructure and Kubernetes clusters (AWS/GCP...)
Understanding of modern development and operations processes and methodologies
Experience with Linux administration
Experience with CI/CD management (Argo project)
Experience with configuration management (e.g. Terraform, Ansible, Helm, Docker, ...)
Knowledge of GitOps principles is nice to have (e.g. ArgoCD)
Experience with monitoring stack (preferably Prometheus, Grafana, Alertmanager), configuration of monitoring rules, creating dashboards, etc.
Understanding of the DevOps/SRE philosophy

Some of your attributes are:

Good at problem-solving and debugging
Can-do approach
Passionate about new technologies and not afraid to try them out
Desire to constantly improve infrastructure, internal components and whatever that you see as a problem
