We design, build, and operate a new class of digital infrastructure – the AI Factory. Through our model-to-grid technology approach, we have pushed the boundaries of multi-generational liquid cooling systems, energy management, AI software orchestration, and construction. For our customers, this approach allows us to make every watt count and deliver low-cost AI tokens globally.    Firmus AI Cloud <span data-ccp-parastyle="FIR Body" data-ccp-parastyle-defn="{"ObjectId":"baa2b379-a6d3-56f4-af2b-6a08de9434e5|1","ClassId":1073872969,"Properties":[469777841,"Aeonik",469777842,"Aeonik",469777843,"Aeonik",469777844,"Aeonik",469769226,"Aeonik",201342446,"1",201342447,"5",201342448,"1",201342449,"1",201341986,"1",268442635,"20",335551500,"197122",335559740,"264",201341983,"0",335559738,"145",469775450,"FIR Body",201340122,"2",134234082,"true",134233614,"true",469778129,"FIRBody",335572020,"1",469778324,"Body Text"]}">Our large-scale GPU cloud platform, Firmus AI Cloud, is purpose-built to deliver energy-efficient AI compute at scale to customers.  It empowers developers, enterprises, educational institutions, and government users to train and deploy AI models with unmatched efficiency and cost savings. With an ever-growing suite of services and applications, we are committed to delivering a cloud experience that is market-leading, proprietary, and built to scale.    Role Summary Every AI feature we ship touches thousands of GPUs. The Senior DevOps Engineer will build the release engineering backbone—CI/CD pipelines, automated testing gates, one-click deployments with instant rollback—that lets Firmus scale fast and responsibly.  You're the bridge between engineering and operations: setting Firmus standards for how code gets to production, mentoring the team on deployment safety, and driving a blameless culture when things go wrong. Ship safely. Ship often. Ship at scale. Key Responsibilities <ul> <li>Design and maintain team-wide CI/CD pipelines (Jenkins, GitHub Actions, ArgoCD, or equivalent) with automated testing gates, artifact management, and deployments aligned with GPU cluster standards.</li> <li>Implement release engineering best practices: repeatable releases, GitOps workflows, automated rollback, and change management procedure.</li> <li>Build and manage test infrastructure: environment provisioning, data seeding, long-running job validation (especially for distributed training templates and multi-node job submissions).</li> <li>Establish engineering protocols and standards: repo organization, PR templates, code quality gates, dependency scanning, static analysis.</li> <li>Partner with infra teams to ensure AI product features deployment practices meet compliance and security standards for massive GPU clusters.</li> <li>Mentor team on testing strategies, deployment safety, and incident response procedures.</li> </ul> Skills & Experience <ul> <li>5–7 years of CI/CD engineering, release engineering, or DevOps experience</li> <li>Deep expertise in GitHub Actions, GitLab CI, ArgoCD, or Jenkins with multi-stage pipeline design and testing gate implementation.</li> <li>Strong automation scripting (Python, Go, or Bash) for build orchestration and environment templating.</li> <li>Strong Kubernetes fundamentals (hands-on): deep understanding of Pod lifecycle and failure modes (Pending/Running/CrashLoopBackOff/Evicted), Deployments/ReplicaSets, Jobs/CronJobs, Services/Ingress, and how these primitives behave under load and during rollouts.</li> <li>Config & secret management: practical experience designing and operating ConfigMaps and Secrets (including secret rotation patterns), with strong hygiene around least privilege, auditability, and preventing credential leakage into logs/artifacts.</li> <li>Safe rollout patterns: proven experience implementing and operating safe rollout strategies (rolling updates, canary, blue/green), readiness/liveness/startup probes, PodDisruptionBudgets, and rollback procedures—ensuring zero/low-downtime deployments for customer-facing services.</li> <li>Deployment safety & debugging: ability to debug common Kubernetes rollout issues end-to-end (bad probes, misconfigured resources/limits, image pull failures, secret/config drift, node pressure/evictions) and convert learnings into automated CI/CD gates and runbooks.</li> <li>Familiarity with artifact management, versioning strategies, and rollback procedures.</li> <li>Experience integrating testing frameworks into CI pipelines (unit, integration, end-to-end).</li> </ul> Key Competencies <ul> <li>Engineering Velocity & Time-to-Release improves quarter-over-quarter while release standards remain consistent (gates, tests, approvals, auditability).</li> <li>Platform Reliability & Customer Trust remains strong: release-related incidents are rare and recovery is fast; reliability targets are met without "surprise outages."</li> <li>Developer Productivity & Team Scale improves: engineers spend less time fighting CI/CD and more time shipping as the team grows.</li> <li>Cost Efficiency & Resource Optimization improves: CI/CD and test infrastructure costs stay controlled (or decrease per unit of output) as usage scales.</li> <li>Knowledge & Culture Multiplier effect is visible: release/reliability practices become the default across the org and repeat incident classes reduce</li> </ul> Success Metrics <ul> <li>Engineering Velocity & Time-to-Release improves quarter-over-quarter while release standards remain consistent (gates, tests, approvals, auditability).</li> <li>Platform Reliability & Customer Trust remains strong: release-related incidents are rare and recovery is fast; reliability targets are met without “surprise outages.”</li> <li>Developer Productivity & Team Scale improves: engineers spend less time fighting CI/CD and more time shipping as the team grows.</li> <li>Cost Efficiency & Resource Optimization improves: CI/CD and test infrastructure costs stay controlled (or decrease per unit of output) as usage scales.</li> <li>Knowledge & Culture Multiplier effect is visible: release/reliability practices become the default across the org and repeat incident classes reduce</li> </ul> Location & Reporting <ul> <li>Melbourne, Australia </li> <li>Reporting to Head of AI & Applications</li> </ul> Employment Basis Full-time Diversity At Firmus, we are committed to building a diverse and inclusive workplace.
