Role Overview

d-Matrix's SRE team owns the infrastructure layer that every engineering team and customer depends on — colocation facilities, on-premises GPU clusters, cloud environments, and the platform services used to deploy and validate d-Matrix hardware and software. This role is a core member of that team, responsible for reliability, automation, and observability across colo, on-premises lab, and cloud environments. You will own systems end-to-end, from provisioning through live incident response, partnering with hardware and software teams on CI/CD, QA, and HPC workloads for silicon development, as well as supporting customer-facing environments where d-Matrix partners collaborate on deployments. This is hands-on, high-ownership work: you'll build and operate real infrastructure, not manage tickets.

What You Will Do

• Own reliability and availability across 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, networking, storage, and hardware troubleshooting — from bare metal through auto-scaling Kubernetes environments.

• Lead capacity planning and hardware lifecycle management for your domains, and track cloud spend to support FinOps and workload placement decisions.

• Drive all provisioning, deployment, and operational changes through Terraform and/or Ansible rather than manual steps, and contribute to shared IaC modules used across the global SRE and data center services teams.

• Build and document automation that eliminates toil — host lifecycle management, fleet health checks, auto-remediation, self-service tooling, and networking automation for cluster interconnects and lab configurations.

• Design and maintain monitoring, alerting, and SLIs (Prometheus/Grafana, DataDog, Splunk, or equivalent), contributing to AIOps-driven detection workflows.

• Participate in on-call rotation, triaging and resolving incidents from bare metal to application layer, and produce high-quality RCAs for P0/P1 incidents.

• Support platform services used by internal teams and external customers, ensuring QoS and uptime commitments and documenting operational runbooks.

What You Will Bring

• Bachelor's or Master's in Computer Science, Electrical Engineering, or a related field (or equivalent experience); 7+ years in SRE, infrastructure engineering, or systems administration.

• Strong Linux systems knowledge with hands-on colocation or on-premises server infrastructure — networking, storage, systemd, kernel parameters, performance diagnostics, physical hardware, rack networking, and bare-metal provisioning.

• Production IaC experience with Terraform and/or Ansible — writing and maintaining configurations, not just running existing playbooks.

• Kubernetes operational experience: cluster troubleshooting, workload management, storage, and networking.

• Experience with observability tooling — Prometheus/Grafana, DataDog, Splunk, or equivalent — including building dashboards and writing alert rules.

• Production-quality Python and/or Bash scripting, paired with incident response experience: structured triage, RCA production, and follow-through on action items.

Preferred Qualifications

• Experience operating customer-facing infrastructure or platform services with external reliability expectations.

• Cloud infrastructure operations across AWS, Azure, or GCP, including hybrid environments spanning cloud and on-prem.

• Experience deploying and operating AI-driven infrastructure tools — AIOps platforms, intelligent alerting, anomaly detection, or LLM-assisted diagnostics — in production.

• HPC job scheduler experience: Slurm, LSF, or equivalent.

• Knowledge of high-speed interconnect fabrics: InfiniBand, RoCE, or NVLink.

• Experience with large-scale infrastructure automation — host lifecycle management, fleet auto-healing, or AIOps-driven operations — building tooling that reduces manual intervention, not just running it.
