Role Description

We are seeking a highly experienced and proactive Senior Systems Analyst to play a pivotal role in the next stage of our cloud journey. You will bridge the gap between our migrated infrastructure and our future-state, optimized cloud architecture. Your core mission will be to discover
,
analyze, and document the application landscape on our new AWS servers, and then lead the creation of robust architectural documentation for the redesigned environment.

This is a hands-on, analytical role requiring deep technical understanding, exceptional documentation skills, and a strategic mindset focused on cloud cost optimization and best practices.

A succesful candidate will:

  • Act as a key liaison between the cloud engineering team, project management, and business stakeholders.
  • Ensure all documentation adheres to internal standards and is stored in a centralized repository (e.g., Confluence, SharePoint).
  • Participate in cost-optimization workshops and provide data-driven insights to support decision-making.

Application Discovery & Analysis

·      Conduct in-depth discovery and dependency mapping of applications now running on the migrated AWS servers (EC2, containers, etc.).

·      Document the purpose, business owner, users, and criticality of each application.

·      Analyze and document current integration points, data flows, and dependencies between applications and with on-premises systems.

·      Profile application behavior: resource utilization patterns (CPU, memory, I/O), network traffic, and performance baselines.

·      

Create and maintain a comprehensive Application Portfolio inventory with clear metadata.

Architectural Design & Documentation

  • Collaborate closely with Cloud Architects and DevOps engineers to analyze the "as-is" data and propose cost-saving redesigns (e.g., re-platforming, right-sizing, leveraging AWS managed services).
  • Translate high-level architectural designs into detailed, clear, and standardized technical documentation.
  • Produce and maintain system architecture diagrams, data flow diagrams, and component specifications for the new, optimized environment.
  • Document proposed changes to networking (VPC, subnets, security groups), storage strategies, and backup/DR configurations.

·      

Create detailed runbooks and operational guides for the newly architected solutions.

Qualifications

·      National Diploma/B.Tech/BSc in Information Technology or relevant testing experience AND/OR Relevant Bachelor's Degree.

· years of proven experience as a Systems Analyst.

·      At least 2 years of experience in the Insurance/financial services industry.

·      Expertise in creating technical documentation: architecture diagrams, system specifications, data flow diagrams, and process workflows.

·      Proficiency with discovery and analysis tools (e.g., AWS Application Discovery Service, manual log analysis, CMDB tools, etc.).

·      Excellent analytical and problem-solving skills with the ability to unravel complex system interdependencies.

·      Outstanding communication skills – able to distill technical complexity into clear written and visual formats for both technical and non-technical audiences.

·      Solid understanding of core IT infrastructure concepts: networking, security, storage, and operating systems (Windows/Linux).
