Together, we can help shape the endless possibilities of AI.  About d-Matrix d-Matrix designs and manufactures purpose-built AI inference silicon. Our SRE team owns the infrastructure layer that every engineering team — and our customers — depends on. That means colocation facilities, on-premises GPU clusters, cloud environments, and the platform services customers use when deploying and validating d-Matrix hardware and software. This is a 6-month contract with potential conversion to full-time. It is a hands-on, high-ownership role. You will build, operate, and automate real infrastructure — not manage tickets. The systems you keep running directly enable silicon development, AI/ML research, and customer success. 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. What You Will Do Infrastructure Operations - 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. Automation & Infrastructure as Code - 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. Observability & Incident Response - 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. Customer & Platform Services - 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. Documentation & Collaboration - 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. What You Will Bring Required - 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 colocati
