Senior Site Reliability Engineer — Observability Engineer

THE WORLD’S MOST ADVANCED VPN, AND A WHOLE LOT MORE.

If you’re a curious problem-solver who carves their own path, join the team behind Threat Protection Pro, the NordLynx protocol, and the fastest VPN on the planet—tools that put privacy, security, and control back in people’s hands.

Your impact? Helping millions take back control of their online security, privacy, and data.

NordVPN runs a global edge infrastructure serving millions of users. Knowing what's happening across that infrastructure - in real time, at scale, without drowning in noise - is what this role exists to solve.

We're looking for a Senior Site Reliability Engineer (SRE) focused on observability: designing monitoring systems, improving signal quality, reducing alert fatigue, and collaborating with data teams on anomaly detection. You'll own how we understand the health and behavior of our distributed systems.

MAIN RESPONSIBILITIES

• Design, build, and improve monitoring pipelines and observability tooling across globally distributed infrastructure
• Define and implement service-level monitoring based on golden signals (latency, traffic, errors, saturation)
• Reduce alert fatigue - build meaningful, actionable alerts that engineers trust
• Develop and maintain custom exporters, scripts, and integrations for metrics and log collection
• Collaborate with the data team on anomaly detection and data-driven operational insights
• Understand service signals - know what to measure, why, and what the numbers actually mean

CORE REQUIREMENTS

• Distributed systems observability - monitoring architecture, signal design, dashboarding
• Golden signal thinking - you design monitoring around what matters, not what's easy to measure
• Alert design - reducing noise, building actionable alerts, managing on-call sanity
• Python - scripting, custom exporters, automation, data processing
• Linux administration and debugging
• Networking fundamentals

BONUS POINTS FOR

• SaltStack
• Advanced networking - traffic analysis, protocol-level debugging
• Advanced data knowledge - aggregation strategies, downsampling, cardinality management, retention trade-offs
• Proven track record of onboarding new systems/services into monitoring from scratch
• Familiarity with agentic engineering - Claude Code, LLM integrations, MCP workflows

TOOLS YOU WILL USE

• Naemon (Nagios) and Gearmand
• Prometheus-based exporters
• Telegraf
• Fluent Bit
• VictoriaMetrics ecosystem
• OpenSearch
• Grafana
