Contract Site Reliability Engineer, d-Matrix

• Bachelor's or Master's in Computer Science, Electrical Engineering, or a related field (or equivalent experience); 5+ years in SRE, infrastructure engineering, or systems administration
• Strong Linux systems knowledge: networking, storage, systemd, package management, kernel parameters, and performance diagnostics
• Hands-on experience with colocation or on-premises server infrastructure — physical hardware, rack networking, and bare-metal provisioning
• IaC experience with Terraform and/or Ansible — writing and maintaining production configurations, not just running existing playbooks
• Kubernetes operational experience: cluster troubleshooting, workload management, storage, and networking
• Prometheus + Grafana or DataDog: building dashboards, writing alert rules, and understanding signal quality
• Python and/or Bash scripting: production-quality automation, not just one-off scripts
• Incident response experience: structured triage, RCA production, and follow-through on action items
• Comfort operating in fast-moving startups: you own your systems, document what you build, and iterate without waiting for perfect requirements

Desirable

• The Role: 6-month contract with potential conversion to full-time
• You will be a core member of the d-Matrix SRE team, responsible for the reliability, automation, and observability of the infrastructure that the company runs on
• You will work across colocation, on-premises lab environments, and cloud platforms—and you will own your systems end-to-end, from initial provisioning through live incident response
• You will work closely with the senior DevOps lead team, whose CI/CD pipelines and automation layer depend on the infrastructure you operate
• You will also support customer-facing environments where d-Matrix partners collaborate on hardware and software deployments
• Own reliability and availability of assigned infrastructure domains: colo server fleets, on-premises lab clusters, cloud environments (AWS, Azure, GCP), and customer-facing platform services
• Perform hands-on infrastructure work: server provisioning, OS configuration, network setup, storage management, and hardware troubleshooting from bare metal up
• Support and operate high-speed interconnect environments — InfiniBand, RoCE, or high-speed Ethernet — in lab and colo settings
• Conduct capacity planning and hardware lifecycle management for assigned infrastructure domains
• Own IaC and configuration management (Terraform, Ansible) for your infrastructure domains — all provisioning and changes through code, not manual steps
• Build automation to eliminate toil: host lifecycle management, fleet health checks, auto-remediation workflows, and self-service tooling for engineering teams
• Develop networking automations for cluster interconnects, VLAN management, and lab network configurations
• Contribute to shared IaC modules and automation libraries used across the SRE team
• Design and maintain monitoring dashboards, alerting, and SLIs (Prometheus/Grafana, DataDog) for your infrastructure domains—ensuring signal quality and actionable alerts
• Participate in on-call rotation; triage and resolve incidents from bare metal to application layer, distinguishing infrastructure faults from software or hardware product issues
• Produce high-quality RCA reports for P0/P1 incidents with root cause analysis and tracked action items
• Detect performance issues, recommend solutions, and implement fixes that permanently improve system reliability
• Support and operate platform services used by external customers for hardware and software deployment collaboration with d-Matrix
• Ensure QoS and uptime commitments for customer-facing environments; escalate reliability risks proactively
• Document platform configurations, access procedures, and operational runbooks for customer environments
• Maintain high-quality runbooks, architecture diagrams, and troubleshooting guides—documentation is part of the job, not an afterthought
• Partner with the DevOps team to ensure infrastructure reliability supports CI/CD pipeline performance and developer experience
• Serve as a technical resource for engineering teams—sharing operational knowledge and raising infrastructure risks early
