• Comprehensive Technology Breadth: Direct solutions spanning Linux/Windows, middleware, enterprise databases, SAN/NAS storage, advanced networking, and security protocols.
• Strategic Governance Leadership: Ratify solution security designs, guide technology decision-making, and build consensus across cross-functional business units.

Responsibilities

• Design, develop, and maintain comprehensive architecture frameworks, strategies, policies, guiding principles, and enterprise standards.
• Architect resilient, scalable, and cost-effective solutions spanning on-premises systems, public cloud, and hybrid cloud topologies (primarily Microsoft Azure).
• Evaluate security standards, conduct technical risk assessments, and collaborate with security partners to ratify solution designs and mitigate potential vulnerabilities.
• Review, evaluate, and approve detailed solution architectures and technical designs to ensure strict compliance with enterprise standards and architectural patterns.
• Collaborate with application engineering and infrastructure teams to evaluate business requirements and recommend optimal architecture options.
• Construct Requirements Traceability Matrices (RTM) to ensure complete alignment from initial business requirements through to solution delivery.
• Evaluate middleware, database, network, and storage components—including Linux, Windows, JBoss, Node.js, Spring Boot, Oracle RAC, MS SQL, Mongo, Cassandra, SAN/NAS, and CDN platforms.
• Guide project plans, estimate technology costs, manage architectural deliverables, communicate progress, and elevate critical risks promptly.
• Conduct pre- and post-implementation reviews to validate solution performance, identify architectural gaps, and establish patterns for future deployments.
• Build consensus and facilitate decision-making across multidisciplinary teams to ensure IT strategies align with long-term technology roadmaps.

Qualifications

• Architecture Tenure: Minimum 10+ years of professional experience in enterprise infrastructure architecture, solution design, and systems engineering.
• Hybrid & Azure Cloud Mastery: Proven experience designing on-premises, public, and mixed hybrid cloud solutions, with strong architectural expertise in Microsoft Azure.
• Operating Systems & Application Stacks: Extensive experience with Linux and Windows server environments, alongside modern application stacks (JBoss, Node.js, Spring Boot).
