Core Responsibilities

Primary Functions

Architect, design, and implement robust, scalable, and secure cloud infrastructure on platforms like AWS, GCP, or Azure, serving as the subject matter expert for the organization.
Lead the strategy and execution for our Infrastructure as Code (IaC) practice, establishing standards and patterns using tools like Terraform, Pulumi, or CloudFormation.
Develop and maintain sophisticated, multi-stage CI/CD pipelines to fully automate the build, test, and deployment of our applications and services using tools like GitLab CI, Jenkins, or Argo CD.
Champion and implement advanced observability strategies, integrating logging, monitoring, and tracing solutions (e.g., Prometheus, Grafana, Datadog, OpenTelemetry) to ensure proactive issue detection and deep system insight.
Spearhead the design and management of our container orchestration platform (Kubernetes, EKS, GKE), focusing on cluster lifecycle management, security, and operational efficiency.
Drive cost optimization initiatives across our cloud footprint by analyzing usage patterns, implementing auto-scaling policies, and identifying resource-saving opportunities.
Act as a key technical leader and mentor for junior and senior engineers, fostering a culture of technical excellence, collaboration, and continuous improvement.
Lead the technical response to major production incidents, conduct blameless post-mortems, and drive the implementation of preventative measures to improve system reliability.
Design and implement comprehensive disaster recovery and high-availability strategies to meet and exceed service level objectives (SLOs).
Integrate security best practices directly into the development lifecycle (DevSecOps), implementing automated security scanning, secret management, and IAM policies.
Evaluate, prototype, and recommend new technologies and tools to solve business problems and improve the developer experience and operational efficiency.
Automate manual and repetitive operational tasks by developing custom scripts and tooling, primarily using languages like Python, Go, or Bash.
Collaborate closely with software development teams to influence application architecture, ensuring new services are designed for scalability, reliability, and operability from day one.
Define and enforce Git branching strategies and repository management best practices, potentially leading the adoption of GitOps principles for infrastructure management.
Establish and govern infrastructure standards, creating reusable modules and blueprints that empower other teams to self-serve their infrastructure needs safely and efficiently.
Conduct in-depth performance analysis and system tuning across the stack, from the network and OS level to the application runtime, to ensure optimal performance.
Own the technical roadmap for critical infrastructure components, translating business requirements into long-term architectural solutions.
Develop and maintain comprehensive documentation for our infrastructure, processes, and runbooks to facilitate knowledge sharing and streamline operations.
Lead cross-functional initiatives to improve platform resilience, such as implementing chaos engineering experiments or improving deployment strategies (e.g., canary, blue-green).
Manage and maintain core infrastructure services such as service mesh (e.g., Istio, Linkerd), API gateways, and message queues (e.g., Kafka, RabbitMQ).
Provide expert-level troubleshooting for the most complex system issues, spanning multiple services, and infrastructure layers.

Secondary Functions

Support and enable development teams by providing self-service tools and platforms that improve their productivity and autonomy.
Contribute to the organization's technical strategy and long-term architectural roadmap by providing infrastructure and operations expertise.
Collaborate with security and compliance teams to ensure the infrastructure meets all regulatory and internal governance requirements.
Participate in architectural review boards and sprint planning ceremonies, providing critical feedback on operational readiness and scalability.
