SRE/Infrastructure Engineer (Telcom)

We’re hiring an experienced SRE / DevOps Engineer to help build and secure complex on-premise infrastructure for a major European telecom. This isn’t just another cloud-native project.  It’s a high-impact observability platform designed for scale, security, and performance.

About the product:

You’ll be working on a mission-critical observability platform that one of Europe’s largest telecom operators uses. The product ingests and processes millions of metrics per second from network devices across multiple countries - ensuring real-time visibility, performance monitoring, and compliance at scale.

We’re transitioning from SNMP-based monitoring to modern streaming telemetry over gRPC, deploying infrastructure and data pipelines in Kubernetes.

What will you be working on?

• Designing and preparing on-premise Kubernetes deployments in new countries and administering existing k8s clusters (updates, monitoring)
• Operating high-security environments (offline installations, configuring SELinux)
• Defining and updating hardening plans for clusters
• Automating operations and repetitive tasks using Ansible
• Collaborating on Grafana dashboard development and integration with observability pipelines
• Supporting developers with deployments and troubleshooting infrastructure-related issues

Why join us? 🌟

• At DNA we believe in clear communication - we regularly talk about what’s working, what’s not, and how we can make things better (not just in code)
• We take care of you - private healthcare, a multisport card, and regular “how are you doing?” check-ins are part of our routine
• Growth - you get 4 hours a week for learning, mentoring, English lessons, and anything that supports your development
• We hang out beyond the code - team lunches are a thing, and if you’re coming from another city, we’ll cover your travel and hotel
• We don’t do layers of management - everyone has a voice and real influence on how we work

What are we looking for? 🕵️‍♀️

• 5+ years of experience as an SRE, DevOps, or Infrastructure Engineer
• Strong hands-on knowledge of Kubernetes administration and deployment (including on-premise setups)
• Proficiency in Linux systems, including SELinux, systemd, and low-level troubleshooting
• Solid understanding of networking (WireGuard, BGP, iptables, IPSec, routing principles)

What makes you a perfect match? 🎯

• You enjoy solving complex infrastructure problems with little guidance or documentation
• You are motivated by technical depth, not just surface-level cloud tooling
• You feel comfortable operating in enterprise environments with strict access policies
• Being a good communicator, able to explain technical details clearly to developers and stakeholders
