Job description

We are seeking a highly skilled Technical System Analyst to lead application discovery, impact assessment, dependency analysis, and migration assessment activities as part of a large-scale IBM WebSphere 8.5.5 to Tomcat on Kubernetes modernization initiative.

The role will focus on understanding the existing application landscape, analyzing WebSphere-specific implementations, identifying application and service dependencies, assessing migration impacts, and defining technical migration requirements for Java-based applications deployed across two independently managed platforms. The engagement involves a lift-and-shift migration with Java upgrades while preserving existing SOAP interfaces, consumer integrations, security mechanisms, and business functionality.

Key Responsibilities

Current State Assessment

Perform detailed analysis of IBM WebSphere 8.5.5 hosted applications and environments.

Document existing application architecture, deployment topology, integrations, and configurations.

Assess Java runtime dependencies and compatibility for Java version upgrades.

WebSphere & Tomcat Migration Analysis

Analyze WebSphere-specific components and recommend equivalent Tomcat configurations.

Evaluate migration requirements for:

JNDI configurations

JDBC connection pools

JMS resources

Security configurations

Session management

Web Services & Integration Analysis

Analyze SOAP-based web services and service contracts.

Identify service consumers and integration touchpoints.

Assess impact of infrastructure and platform migration on service consumers.

Validate that existing SOAP interfaces remain unchanged post migration.

Dependency Mapping & Impact Assessment

Perform application dependency analysis.

Identify upstream and downstream integrations.

Analyze backend database interactions and data flows.

Produce application and interface dependency maps.

Security Assessment

Analyze existing SAML-based authentication and authorization mechanisms.

Assess migration impact on identity and access management integrations.

Validate compatibility with the target platform.

Create Technical Documentation

Service catalog

Current and target-state diagrams

Gap analysis documents

Risk and mitigation reports

Stakeholder Collaboration

Work closely with architects, developers, middleware teams, infrastructure teams, and application owners.

Facilitate requirement gathering and technical workshops.

Support migration planning and execution teams through design reviews.
