Small, experienced team in Copenhagen

Competitive salary based on experience

Flexible hours and autonomy

Job summary

Cobira is seeking a mid-level SRE to own observability and alerting across our platform. You’ll drive the evolution from New Relic foundations to broader monitoring, dashboards, and reliable incident response.

You’ll write code, design alert architectures, and work with engineers to understand the system when it’s on fire. You’ll collaborate with platform engineers on SLIs/SLOs, contribute to infra work, and thrive in a compact, hands-on team in Copenhagen.

Qualifications

• 3–5 years in SRE, platform engineering, or a strong DevOps role.
• Hands-on observability: alerting, dashboards, tracing, logging using NR/Datadog/Grafana.
• Solid Linux fundamentals and cloud VM experience.
• Experience with containerised workloads (Docker, Docker Compose).
• Systematic debugging approach and clear documentation.

Responsibilities

• Own and mature our observability stack — alerting policies, dashboards, on-call runbooks, and incident response workflows
• Design and tune alert conditions in New Relic (NRQL, baseline/anomaly detection, composite conditions) to minimize noise and maximize signal
• Identify gaps in our monitoring coverage across services, message queues, infrastructure, and network links
• Build and maintain tooling that helps the team understand system behavior — not just when things break, but before they do
• Scripting ability in Python - enough to automate, glue systems together, and write a useful tool when one doesn't exist
• Collaborate with platform engineers on SLIs, SLOs, and error budgets
• Participate in on-call rotation and drive post-incident improvements
• Contribute to infrastructure work when needed

Job description

The Role

We're looking for a mid-level SRE to own observability and alerting across our platform. Right now our monitoring lives primarily in New Relic, and while we've built solid foundations - Kafka consumer lag tracking, infrastructure health dashboards, custom NRQL alert policies - we know there's a lot more to do.

You'll be the person driving this forward.

This isn't a pure ops role. You'll write code, design alerting architectures, and work closely with the engineers shipping the platform. When something is on fire, you'll be one of the people who actually understands why.

What You'll Do

• Own and mature our observability stack — alerting policies, dashboards, on-call runbooks, and incident response workflows
• Design and tune alert conditions in New Relic (NRQL, baseline/anomaly detection, composite conditions) to minimize noise and maximize signal
• Identify gaps in our monitoring coverage across services, message queues, infrastructure, and network links
• Build and maintain tooling that helps the team understand system behavior — not just when things break, but before they do
• Scripting ability in Python - enough to automate, glue systems together, and write a useful tool when one doesn't exist
• Collaborate with platform engineers on SLIs, SLOs, and error budgets
• Participate in on-call rotation and drive post-incident improvements
• Contribute to infrastructure work when needed

What We're Looking For

• 3–5 years of experience in SRE, platform engineering, or a strong DevOps role
• Hands-on experience building and maintaining observability systems (alerting, dashboards, tracing, logging) - New Relic, Datadog, Grafana, or similar
• Solid Linux fundamentals and comfort operating in cloud-hosted VM environments
• Experience with containerised workloads (Docker, Docker Compose)
• A systematic approach to debugging - you form hypotheses, isolate variables, and document what you find
• Good written communication; we write things down

Nice-to-have

• Experience with Kafka or other message streaming systems
• Experience with Redis or other caching technologies
• Familiarity with network-level infrastructure (VPNs, firewall rules, routing)
• Exposure to telecom or IoT connectivity domains
• Experience with NRQL or another query language for observability platforms
• IaC experience (Terraform, Ansible, or similar)
• Familiarity with Kubernetes - we're not there yet, but directionally heading that way

What We Offer

• A technically honest environment - we'll tell you what's messy and where improvement is needed
• Meaningful ownership from day one; no layers of process between you and the problem
• A compact, experienced team in Copenhagen
• Competitive salary based on experience
• Flexible hours and autonomy over how you work, within an on-site team culture
• The chance to shape the reliability culture of a growing IoT and connectivity platform
