Responsibilities

• Full-Stack Network Architecture: Architect, optimize, and troubleshoot complex networking infrastructure spanning Layer 1 through Layer 7, ensuring low-latency data transport, secure edge routing, and seamless service mesh integration
• Grafana Stack Architecture: Design, scale, and optimize our unified observability platform using the Grafana Labs suite (Grafana, Mimir, Loki, Tempo, and Beyla)
• AIOps & Intelligent Alerting: Deploy machine learning models and automated anomaly detection to cut through telemetry noise, reduce alert fatigue, and predict network or data pipeline bottlenecks
• GKE Platform Engineering: Drive the architecture, scaling, security, and networking of production Google Kubernetes Engine (GKE) clusters
• Data & Event Streaming Reliability: Tune, and maintain high-throughput Apache Kafka clusters to guarantee low-latency event delivery and high availability
• Large-Scale Database Management: Ensure the performance, scalability, and disaster recovery readiness of our transactional and analytical data tiers across PostgreSQL, AlloyDB, and BigQuery
• Automated Incident Response: Integrate AIOps insights with Grafana workflows to automate triage, accelerate root-cause analysis, and trigger auto-remediation scripts
• Technical Leadership: Champion the long-term technical roadmap for distributed infrastructure engineering and GCP cloud-native observability standards
• Mentorship: Coach senior and junior engineers on advanced debugging techniques, distributed systems thinking, and intelligent operations across a distributed workforce

Skills

• Proven track record of high autonomy and successful delivery in a 100% remote engineering environment
• 8+ years in SRE, Production Engineering, or Distributed Systems infrastructure roles
• Deep technical knowledge and debugging mastery across all OSI layers, including: L1-L3: Physical/fiber infrastructure awareness, switching, and advanced routing protocols (BGP, OSPF)
• Transport layer tuning (TCP congestion control algorithms, UDP, QUIC)
• Session management, TLS termination, DNS architecture, and advanced application protocols (HTTP/3, gRPC)
• Expert-level mastery of Google Kubernetes Engine (GKE) internals, custom controllers, multi-cluster networking, and GitOps workflows
• Proven track record managing high-throughput Apache Kafka pipelines and large-scale data environments across PostgreSQL, AlloyDB, and BigQuery
• Deep, hands-on experience deploying and managing Grafana Enterprise/Cloud, Prometheus/Mimir, Loki, and Tempo at scale
• Track record applying AI/ML techniques for time-series anomaly detection, log clustering, and correlation (e.g., Grafana Adaptive Metrics, BigPanda)
• Advanced, production-scale expertise utilizing HashiCorp Terraform exclusively to provision and manage multi-region GCP cloud architectures
• High proficiency in Go and Python for building custom infrastructure tooling, Kubernetes operators, and data integration scripts
• Exceptional written and verbal communication skills, with an emphasis on creating clear documentation for asynchronous alignment
• Deep knowledge of Google Cloud architectural best practices, Cloud SDN, Cloud Armor, Interconnect, Identity and Access Management (IAM), and cost optimization
• Deep understanding of Linux internals, eBPF-based monitoring, kernel-level networking, and packet analysis tools (Wireshark, tcpdump)

Benefits

• As a part of the total compensation package, this role may be eligible for a bonus.
