SMBC Interview Preparation

Job Description​

Responsible for Design Assistance & Operationalizing related infrastructure services to the respective squad and its deliverables. This means working closely with development teams to understand their needs and translating those needs into workable infrastructure solutions, and then making sure those solutions run smoothly.

Create and govern Automation process on infrastructure over the platform and its surroundings. This involves identifying repetitive tasks, designing automation workflows, and implementing them using appropriate tools. Governance ensures consistency and security.

Create and maintain Cloud Infrastructure Orchestration. This focuses on using tools and platforms to automate the deployment, scaling, and management of cloud resources. Think Infrastructure as Code (IaC).

Develops tools, implement & manages all service running both on-premise & public cloud. You will be building and maintaining tools to help manage services regardless of where they are running (on-premise or in the cloud). This includes deployment, monitoring, and troubleshooting.

Engage in service capacity planning & demand forecasting, software performance analysis & system tuning. This role is about ensuring systems can handle the load. It involves monitoring performance, predicting future needs, and optimizing systems to improve their efficiency.

Make sure the high availability of Bank IT System. Ensuring systems stay up and running. This involves implementing redundancy, failover mechanisms, and robust monitoring.

Managing Bank Microsite. Includes ensuring the microsites are functional, secure, and up-to-date.

Creating documentation for troubleshooting & sharing knowledge. Crucial for knowledge transfer and efficient problem solving.

Minimum Requirements - Deep Dive​
