About the Role.

We are looking for a highly experienced Cloud Architecture Leader to drive the strategy, architecture and evolution of our enterprise Cloud platform as part of a major technology transformation.

This role requires a unique combination of strategic leadership and deep hands-on Cloud expertise. The ideal candidate has not only defined Cloud strategies and reference architectures, but has also designed, built and evolved enterprise-scale Cloud platforms and Landing Zones.

The role will provide end-to-end architectural ownership of the Cloud ecosystem, partnering with Architecture, Engineering, Cybersecurity, Infrastructure, Networks, Operations, Finance and Data teams.

We are looking for someone capable of engaging senior stakeholders on Cloud strategy while going deep with engineering teams on architecture, design and implementation. This is not a purely governance-oriented role; real-world implementation experience and strong technical credibility are essential.

Key Responsibilities

Cloud Architecture & Landing Zone

Own and evolve the enterprise Cloud architecture, target state, architectural principles, standards and technology roadmap.

Lead the architecture and continuous evolution of enterprise Cloud Landing Zones and foundational services, including:

• Multi-account environments and Cloud organization models
• Networking and hybrid connectivity
• Identity and Access Management (IAM)
• Security controls, secrets and key management
• Observability, logging and monitoring
• Resilience, backup and disaster recovery
• Infrastructure as Code and automation
• Cloud governance and policy enforcement
• Shared platform services and workload onboarding

Ensure Cloud foundations enable secure, repeatable and scalable adoption across engineering, application, Data and AI teams.

Architecture to Execution

Translate Cloud strategy into implementable architectures, engineering decisions and actionable roadmaps.

Work directly with architects, Cloud engineers and platform teams to challenge designs, identify gaps, evaluate technical trade-offs and drive issues through resolution.

The candidate should be comfortable moving from an executive discussion into detailed technical conversations involving network topology, IAM, security controls, Infrastructure as Code, Cloud-native services, deployment patterns and resilience models.

Architecture ownership must extend beyond documentation: this role is expected to help ensure architecture becomes working technology.

Security, Governance & Risk

Partner with Cybersecurity, Risk and Engineering teams to embed security by design and by default.

Establish guardrails and automated controls that balance regulatory, security, data protection and operational resilience requirements with developer speed and autonomy.

Promote policy-as-code and automated governance, enabling teams to innovate without compromising enterprise controls.

FinOps & Cloud Cost Optimization

Apply FinOps principles and Cloud cost optimization practices across large-scale Cloud environments.

Analyze Cloud consumption and cost drivers, identify optimization opportunities, and ensure architectures balance performance, reliability, scalability and cost efficiency.

Experience should include cost allocation and tagging, budgeting and forecasting, rightsizing, commitment-based discount strategies, storage and data transfer optimization, anomaly detection and unit economics.

Partner with Engineering, Finance, Operations and business stakeholders to establish cost governance, accountability and measurable optimization initiatives, making cost an architectural consideration rather than an after-the-fact exercise.

Cloud Adoption, Data & AI

Create reusable architectures, secure-by-default patterns, paved roads and self-service capabilities that simplify Cloud adoption and improve developer experience.

Enable Cloud environments supporting modern applications, APIs, containers, Kubernetes, Data platforms, analytics, AI/ML and Generative AI workloads.

Partner with Data and AI teams to ensure these capabilities are supported securely, resiliently and cost-effectively at enterprise scale.

Hybrid & Multi-Cloud Architecture

Design architectures integrating Public Cloud with complex enterprise On-Premise environments, including networking, identity, security and operational dependencies.

AWS represents the primary area of technical depth, while the candidate should have sufficient Azure, GCP and multi-cloud awareness to make technology decisions from an enterprise perspective.

Technical Leadership

Provide technical leadership and mentorship to Cloud architects and engineers.

Raise the overall Cloud architecture capability by establishing standards, reference architectures and engineering practices.

Influence decisions across organizational boundaries and build alignment between Architecture, Engineering, Security, Infrastructure, Operations, Finance, Data and senior technology leadership.

What We Are Looking For

The ideal candidate will bring:

• Significant experience in Cloud Architecture, Cloud Engineering or Platform Engineering.
• Proven experience designing and implementing enterprise-scale Landing Zones.
• Deep hands-on AWS expertise, including complex multi-account enterprise environments.
• Strong expertise in Cloud networking, IAM, security, observability, resilience and governance.
• Practical experience with Infrastructure as Code, Terraform, automation and CI/CD.
• Experience designing hybrid Public Cloud / On-Premise architectures.
• Strong understanding of Cloud-native architectures, containers, Kubernetes and APIs.
• Experience with Data, AI/ML and GenAI workloads.
• Strong understanding of FinOps, Cloud economics and cost optimization.
• Practical application of the AWS Well-Architected Framework.
• Working knowledge of Microsoft Azure and multi-cloud concepts.
• Knowledge or practical exposure to Google Cloud Platform (GCP), particularly for Data and AI, is desirable.
• Experience in large, regulated and highly complex enterprises, particularly financial services, is highly desirable.
• Strong executive communication combined with the technical depth to challenge senior architects and engineers.

Certifications & Technical Credentials

Candidates should demonstrate strong and current AWS technical depth, ideally supported by multiple advanced certifications.

Advanced AWS Certifications

Professional and Specialty-level certifications are particularly valued:

• AWS Certified Solutions Architect – Professional
• AWS Certified DevOps Engineer – Professional
• AWS Certified Security – Specialty
• AWS Certified Advanced Networking – Specialty
• AWS Certified Database – Specialty

Additional AWS Certifications & Credentials

Broad AWS certification across engineering, operations, Data and AI is highly desirable:

• AWS Certified CloudOps Engineer – Associate
• AWS Certified Developer – Associate
• AWS Certified Solutions Architect – Associate
• AWS Certified SysOps Administrator – Associate
• AWS Certified AI Practitioner
• AWS Certified Cloud Practitioner
• AWS Well-Architected Proficient
• AWS Cloud Economics

The combination of advanced and associate-level certifications should demonstrate architectural breadth and practical engineering depth, not certification alone.

Additional credentials such as Microsoft Certified: Azure Fundamentals and Enterprise Design Thinking Practitioner – IBM are valuable.

Additional certifications in Kubernetes, Terraform, FinOps, Cloud Security or AI are also desirable.

Leadership Profile

We are looking for someone with the ownership, leadership presence and technical credibility to drive Cloud architecture as an enterprise capability.

The successful candidate must be able to:

Set direction — Define the target architecture and pragmatic roadmap.

Drive execution — Translate architecture decisions into technology outcomes.

Challenge and simplify — Identify gaps early and turn complex requirements into clear decisions and patterns.

Stay technical — Maintain the hands-on depth required to challenge designs and engage credibly with senior engineers.

Influence broadly — Align engineering, security, infrastructure, finance, architecture and senior leadership.

Drive economic accountability — Connect Cloud architecture, consumption, cost and business value.

What Success Looks Like

Success means establishing Cloud as a secure, scalable, cost-efficient and high-velocity enterprise capability.

Cloud foundations and Landing Zones are robust and continuously evolving. Architectural gaps are identified early. Security and governance become increasingly automated. Engineering teams have clear patterns and paved roads. Cloud consumption becomes transparent and financially accountable.

Ultimately, this role will establish and evolve the Cloud architecture foundations supporting the organization’s next generation of digital, Data and AI capabilities, while materially reducing the gap between architecture and engineering execution.
