This role is critical for architecting scalable, secure, and observable infrastructure supporting mission-critical applications and LLM (Large Language Model) workloads.

Your Responsibilities:

    • Infrastructure & Cloud Management
    • Deploy and manage Kubernetes clusters (cloud & on-prem) using Terraform and Helm.
    • Design secure network topology (VPCs, VPNs, firewalls).
    • Infrastructure Security & Zero Trust
    • Implement zero trust models, IAM, and least-privilege access.
    • Enforce security policies, micro-segmentation, and secrets management.
  • DevSecOps & CI/CD Security
    • Integrate security scanning, SBOM, and policy-as-code into pipelines.
    • Automate compliance and security checks during build and deploy.
  • LLM & Hybrid Deployments
    • Build and maintain infrastructure for LLM workloads (vLLM, KServe).
    • Support hybrid cloud and on-prem deployments ensuring consistency and security.
  • Monitoring & Observability
    • Implement monitoring, logging, and alerting using Grafana, Azure Monitor, Prometheus.
    • Maintain dashboards, SLIs/SLOs, and performance metrics.
  • Linux & Automation
    • Harden Linux systems, automate routine tasks, and support incident response.
    • Develop scripts and tools to streamline operations.
  • Collaboration & Strategy
    • Partner with engineering, security, and operations teams.
    • Mentor teams on cloud best practices and emerging technologies.

What we look for:

  • Strong experience with Kubernetes, including cluster provisioning, scaling, and security.
  • Proficient in Terraform and Helm for infrastructure-as-code and deployment automation.
  • Expertise in infrastructure security, zero trust models, and IAM best practices.
  • Hands-on experience with DevSecOps: security scanning, SBOM generation, secrets management, and policy-as-code.
  • Solid understanding of cloud networking: VPC design, VPN, and firewall configuration.
  • Experience with hybrid or on-prem deployments alongside cloud environments.
  • Skilled in Linux administration, scripting, and automation for operational efficiency.
  • Familiarity with monitoring and observability tools (Azure Monitor, Grafana, Prometheus).
  • Experience building and managing infrastructure for LLM or AI workloads (vLLM, KServe).
  • Nice - to - have:
    • Cloud and security certifications (e.g., CKA/CKAD, Terraform Associate, CISSP).
  • Experience with GitOps workflows (Argo CD, Flux) and CI/CD security pipelines.
  • Knowledge of policy frameworks (OPA, Gatekeeper, Kyverno) and workload identity systems (SPIFFE/SPIRE).
  • Familiarity with GPU/accelerator-based infrastructure for ML/LLM workloads.
  • Background in SRE practices, including SLO/SLI design and incident response.
  • Contributions to open-source cloud, DevSecOps, or LLM infrastructure projects.
  • What we offer:
    • Competitive salary and performance-based bonuses.
  • Fully remote, flexible work environment.
  • Modern laptop and hardware provided by us.
  • Specialized training in AI, automation, and digital productivity tools.
  • Global exposure—collaborate with top-tier founders and fast-growing startups.
