SeniorSite Reliability Engineer (SRE)

POSITION OVERVIEW : Software Development Senior Specialist POSITION GENERAL DUTIES AND TASKS : Role Summary The Senior Site Reliability Engineer (L7) is a hands‑on technical engineeringrole responsible for building, automating, scaling, and maintaining highlyreliable, secure, and resilient cloud and hybrid infrastructure platforms. The role focuses on cloud infrastructure engineering, container orchestration,Infrastructure‑as‑Code (IaC), observability, incident response, and platform‑levelapplication development. Key Responsibilities Deploy, configure, and maintain AWS resources including EC2, ECS, EKS, VPC,IAM, NAT, and networking components. • Build secure and scalable cloud networking (VPCs, subnets, routing, VPN,firewalls). • Work with load balancers, reverse proxies, API gateways, DNS management, andnetwork routing.• Build CI/CD pipelines using Jenkins, GitLab CI, or GitHubActions. • Support application releases and coordinate deployments across environments. • Implement logging/monitoring using Prometheus, Grafana, Datadog, Splunk, orCloudWatch. • Participate in incident response, troubleshooting, on-call rotation, andpost-incident RCA. • Perform system performance tuning, patching, capacity planning, andoptimization. • Improve system reliability through automation, redundancy, and engineeringbest practices. • Implement and maintain IaC using Terraform or CloudFormation. • Automate provisioning, configuration, and environment setup using scripting(Python, Bash, Go). • Develop reusable automation modules, templates, pipelines, and cloudengineering patterns. • Build, deploy, and manage containerized applications using Docker. • Operate and optimize Kubernetes clusters (EKS or on‑prem). • Implement autoscaling, service mesh, pod security, and workload monitoring. • Develop automation services, internal tooling, and platform utilities usingCore Java, Spring Boot, Quartz, and Erlang. • Build wrappers/services for IBM MQ and RabbitMQ messaging flows. • Create schedulers, orchestration components, and internal micro‑services foroperational tasks. • Write integrations, connectors, and event-driven components forinfra-automation. • Build custom alerts, webhook handlers, log processors, and reliabilitytooling.
