Job description

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 Successful 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.

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.
• 5+ years 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).
