Discover our innovative SecurityTech solutions! Your Responsibilities: * Develop and own the infrastructure and platform roadmap, evaluate and recommend technologies and architectural patterns to support infrastructure scalability, cost efficiency, and agility * Define comprehensive technical specifications, with strong emphasis on non-functional requirements: security (zero-trust, encryption, policy-as-code, compliance frameworks), performance (latency, throughput, high availability, disaster recovery), reliability, observability, and cost optimization * Champion Infrastructure as Code (IaC) and GitOps practices using tools such as Terraform/OpenTofu, Pulumi, Helm, ArgoCD/Flux, and Ansible * Act as a technical leader and mentor to platform engineers, SREs, DevOps teams, and application developers. Foster strong collaboration between infrastructure/platform teams and product/engineering groups * Produce high-quality, living documentation: architecture decision records (ADRs), design blueprints, runbooks, standards & guardrails, and platform user guides; following best practices * Proactively identify, assess, and mitigate infrastructure risks, including security vulnerabilities, single points of failure, compliance gaps, operational drift, and cost overruns Your Qualifications: * 10+ years in infrastructure engineering, platform engineering, SRE, or architecture roles, with5+ years focused on production-scale Kubernetes and cloud platforms * Deep expertise in Kubernetes (architecture, operators, CNI/service mesh, multi-cluster federation, upgrades at scale) * Strong hands-on experience with major cloud providers (AWS, Azure) and hybrid/on-premiss integrations * Proficiency in IaC (Terraform preferred), GitOps, containerization (Docker), CI/CD tooling, and observability (Prometheus, Grafana, ELK/OpenTelemetry) * Solid understanding of databases (relational, NoSQL, distributed), networking (VPC, SDN,load balancing, firewalls), and security best practices (RBAC, secrets management, encryption, vulnerability scanning) * Proven track record defining non-functional requirements and delivering high-availability, performant, secure systems * Excellent communication and leadership skills; experience mentoring teams and influencing stakeholders Your Qualifications: * 10+ years in infrastructure engineering, platform engineering, SRE, or architecture roles, with5+ years focused on production-scale Kubernetes and cloud platforms * Deep expertise in Kubernetes (architecture, operators, CNI/service mesh, multi-cluster federation, upgrades at scale) * Strong hands-on experience with major cloud providers (AWS, Azure) and hybrid/on-premiss integrations * Proficiency in IaC (Terraform preferred), GitOps, containerization (Docker), CI/CD tooling, and observability (Prometheus, Grafana, ELK/OpenTelemetry) * Solid understanding of databases (relational, NoSQL, distributed), networking (VPC, SDN,load balancing, firewalls), and security best practices (RBAC, secrets management, encryption, vulnerability scanning) * Proven track record defining non-functional requirements and delivering high-availability, performant, secure systems * Excellent communication and leadership skills; experience mentoring teams and influencing stakeholders
