Senior Infrastructure Engineer
Location: Remote, United States
Role Overview
Software Infrastructure runs the Kubernetes clusters, CI/CD systems, and compute environments that every d-Matrix engineer builds and tests on, along with the systems behind our externally accessible product demos. As a senior infrastructure engineer, you will be the team’s first responder and own issues end to end: diagnosing them, fixing them, and engaging IT or the product software group when the root cause sits with them. Our environment combines cloud resources, conventional servers, and our own AI accelerators and networking hardware, so quickly isolating the cause is central to the job. When an issue recurs, you will turn it into automation, better alerting, or a runbook. This is not an IT support or ticket-queue role, and IT owns physical hardware; we manage everything from the operating system up. On-call participation is expected.
What You Will Do
Own first response and resolution for issues across Kubernetes clusters, GitLab and CI runners, VMs, standalone systems, and demo environments
Triage across teams with IT and the product software group when the root cause sits on their side
Convert recurring issues into automation, alerts, and runbooks so repeat incidents decline
Improve monitoring and alerting to reduce false alarms and speed detection of real problems
Perform routine operational work, including upgrades, patching, certificate renewals, and capacity checks
Ship automation and improvements the team relies on, beyond individual fixes
Participate in on-call coverage for the environment
Contribute to design and build work across the team’s systems as your scope grows
What You Will Bring
2+ years operating production Linux systems, including hands-on Kubernetes troubleshooting
Methodical debugging skills: forming hypotheses, narrowing them quickly, and working across layers when the obvious answer is wrong
Scripting experience in Python and/or Bash
Familiarity with CI/CD systems (GitLab preferred)
Working knowledge of networking fundamentals, including DNS, routing, load balancing, and TLS
Experience with monitoring and observability tools
Clear communication under pressure, including concise incident status updates
Drive and curiosity to learn unfamiliar systems and how state-of-the-art inference systems are built
Preferred Qualifications
Experience with GPU or accelerator nodes in Kubernetes
Experience with infrastructure-as-code tools such as Ansible or Terraform
Experience with monitoring platforms such as DataDog, Prometheus, or Grafana
Bare metal or on-prem infrastructure experience
CKA or CKAD certification
