Job Purpose:
TESTQ Technologies is an IT Services and Solutions Company whose offerings span over a variety of industry sectors with strong technical, domain, and process expertise helping clients grow their businesses and decrease operational costs on a continuous basis in an ever-changing business environment.
Job Description (Main Duties and Responsibilities):
Design, develop, and maintain Oracle Intelligent Advisor (IA) rulebases, decision services, and interview forms aligned with business and policy requirements. Own end-to-end IA solutions, including modelling, deployment, runtime support, upgrades, and fault resolution across IA and IA Hub.
Lead Oracle WebLogic domain and cluster operations (AdminServer, Managed Servers, NodeManager, deployments, rolling restarts, diagnostics). Administer RHEL environments (configuration, patching, hardening, SELinux, firewalld, housekeeping).
Configure Apache HTTPD reverse proxy (routing, TLS, certificate renewal, health checks, traffic management). Develop and support Java-based integration services (SOAP, REST APIs, batch processing) ensuring performance, resilience, and reliability.
Implement secure integrations using REST/JSON, SOAP, OAuth2, OIDC, and mTLS. Design and manage CI/CD pipelines in Azure DevOps (builds, deployments, approvals, rollback). Manage secrets and certificates via Azure Key Vault or equivalent.
Monitor system performance across ingress, application, integration, and data layers; implement tuning and capacity planning. Design monitoring, logging, and alerting for proactive issue resolution. Support incident management, root cause analysis, and disaster recovery.
Ensure compliance with OWASP, CIS benchmarks, GDS, and ITHC standards. Implement accessibility (WCAG 2.2 AA, ARIA, cross-browser/device compatibility). Develop SQL Server components (schema, stored procedures, audit data).
Support release management (ServiceNow change requests, CAB approvals, deployments). Collaborate with infrastructure and security teams on RHEL diagnostics, patching, and hardening.
Maintain Apache HTTPD reverse proxy knowledge (TLS, routing, health checks). Support production Java services with JVM tuning (heap, GC, large payloads). Contribute to security assurance (OWASP, OAuth2, OIDC, mTLS, audits).
Operate within enterprise change/release frameworks (ServiceNow, CAB, incidents, DR). Familiarity with Azure services (Key Vault, API Management, Azure SQL) including secure secret and certificate lifecycle management.
Key Skills, Qualifications and Experience Needed [The candidate must demonstrate these in all stages of assessment]
Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field (or equivalent practical experience).
Proven experience in Oracle Intelligent Advisor (IA), including rulebase development, policy modelling, deployment, and runtime support.

Experience in designing and developing IA Web Determinations, including custom controls using raw JavaScript without frameworks.
Proficiency in Java SE for building long-running services, batch processing, and integration components.
Hands-on experience with SOAP and REST-based integrations, including contract management and API design.
Strong understanding of security protocols and configurations, including OAuth2, OIDC, TLS, mTLS, keystores, and truststores.
Experience in JVM tuning, including heap management, garbage collection, and handling large data or BLOB processing.
Solid knowledge of resilience engineering principles such as retries, timeouts, and idempotency.
Experience administering Oracle WebLogic environments, including domain setup, clustering, scaling, and performance tuning.
Strong Linux administration skills, particularly in RHEL environments (systemd, SELinux, firewalld, cron, patching).
Hands-on experience with Azure DevOps, including repositories, pipelines, CI/CD implementation, and release automation.
Familiarity with Azure services such as API Management, Key Vault, Storage Accounts, and Azure SQL.
Experience in multi-component deployment strategies, including rollback and environment management.
Strong understanding of data architecture, including data ingestion, transformation, lineage, and handling structured/unstructured data at scale.
Experience working with SQL Server, including schema design and performance considerations.
Experience with ServiceNow or similar tools for change and release management.
Strong understanding of OWASP security principles, CIS benchmarks, and vulnerability remediation processes.
Knowledge of accessibility standards (WCAG 2.2 AA) and implementation practices.
Proven technical leadership of mission-critical IA or rules-based digital services particularly in a government setting
