Senior SRE

Location: UK - 100% Remote

Duration: 12-Month Initial Contract

Working Hours: 11:00 AM - 7:00 PM (Mostly)

Our client is looking for a Senior SRE to lead the design and evolution of a global observability stack that supports millions of customer devices across 8 international data centers. This isn't just about monitoring; it's about building the high-performance, distributed systems that ensure our global cloud remains performant while scaling 2-3x every year.

As a Lead on the Observability team, you will dive into projects that define "large-scale":

• Metrics at Scale: Design and scale a Prometheus architecture to handle 100M+ active series and beyond.
• Petabyte Logging: Operate high-performance ElasticSearch clusters holding 2000+TB of data.
• High-Throughput Pipelines: Grow data pipelines built on Kafka, handling hundreds of thousands of events per second.
• Engineering Autonomy: Write libraries and APIs (Ruby, Go) that provide engineers with self-service access to monitoring and logging systems.
• Infrastructure as Code: Leverage Terraform and Ansible to deploy across both public and private cloud environments.

• Distributed Systems Expert: 5+ years of experience operating mid-to-large scale systems on Linux (Debian/Ubuntu)-whether on VMs or bare metal.
• The "S" in SRE: 2+ years of development experience with Ruby, Go, Python, or Scala. You prefer building tools to manual toil.
• Observability Specialist: Direct experience with Prometheus/Thanos/Cortex, ELK (Elasticsearch, Logstash, Kibana), Kafka, and Grafana.
• Automation Mindset: Strong proficiency in Terraform, Ansible, and Consul for infrastructure orchestration.
• Problem Solver: You are comfortable diving into unfamiliar codebases and have a deep understanding of software engineering best practices.
• Availability: You are comfortable being part of a production on-call rotation and working a shift that primarily covers 11:00 AM to 7:00 PM UK time.

If you are interested then let me know and we can have a confidential chat. You can also drop me your CV and I will get back to you on call directly to discuss the role further.
