Enterprise Solutions Architect

Architecture Leadership & Governance

Provide technical authority and architecture governance across all programme work streams, ensuring consistency, scalability, and resilience of the overall solution.

Define and maintain solution architecture patterns, design standards, and best practices for Oracle, Azure IaaS, and hybrid environments.

Own the technical design documentation and architecture decision records (ADRs), keeping them current as the solution evolves.

Continuously refine the architecture as new issues, dependencies, and risks are identified across the programme lifecycle.

Ensure all solution designs meet security standards, compliance requirements, and risk mitigation frameworks.

Facilitation of workshops and requirements discovery bringing teams together to align on value driven business outcomes.

Lead the definition and execution planning for the Oracle database upgrade strategy, including version assessment, upgrade path selection, and go/no-go criteria.

Perform in-depth analysis of the Oracle database estate alongside Oracle SMEs, identifying performance issues, risks, inefficiencies, and version-specific constraints.

Develop technical recommendations and mitigation strategies for issues uncovered during analysis, including schema changes, deprecated feature remediation, and compatibility fixes.

Design workarounds and optimisation approaches for complex Oracle challenges, adapting the solution iteratively as new problems emerge during execution.

Validate Oracle upgrade outcomes through structured performance benchmarking, regression testing governance, and post-upgrade health checks.

Lead the technical strategy for VMware decommissioning, covering workload inventory, dependency mapping, and VM re-platforming prioritisation.

Assess each workload’s characteristics (performance, latency, licensing, OS, connectivity) to determine optimal re-platforming approach: lift-and-shift, re-platform, or re-architect.

Define and govern the migration sequencing plan, managing technical interdependencies and minimising service disruption during the removal of the VMware layer.

Identify and resolve technical blockers arising from VMware-specific configurations, custom networking, and storage dependencies.

Architect the migration from Azure VMware Solution (AVS) to native Azure IaaS, leveraging Azure Migrate, ASR, and related tooling.

Redesign workload architectures for Azure-native patterns where appropriate — including compute sizing, managed disk selection, virtual networking, and availability zone placement.

Define and enforce networking migration patterns, including VNET design, NSG rulesets, private endpoint configurations, and Express Route / VPN continuity.

Manage Azure landing zone readiness, ensuring governance controls, RBAC, tagging policies, and security baselines are in place before workload migration.

12–18+ years in solution architecture or technical leadership roles, with a consistent track record of delivery in large-scale enterprise transformation programmes.

Deep, hands‑on Oracle expertise: performance tuning, version upgrades (e.g. 11g to 19c), migration planning, schema analysis, and post‑upgrade remediation.

Proven Azure cloud architecture experience:
IaaS design (VM, storage, networking, identity), Azure Migrate, ASR, landing zones, and hybrid connectivity.

Direct experience delivering VMware workload migrations — including AVS, vSphere, and vCenter environments — to cloud‑native or IaaS targets.

Strong understanding of enterprise security principles: identity & access management, network security, encryption at rest/in transit, and compliance frameworks.

Background in consulting or professional services, with experience producing client‑facing architecture artefacts and presenting to senior technical audiences.

Exposure to regulated industries — BFSI, Capital Markets, or Enterprise Transformation environments strongly preferred.

Serve as the senior technical point of contact for client architecture and engineering stakeholders, communicating complex decisions with clarity and…
