Senior Cloud Solutions Architect

Senior Cloud Solutions Architect - Azure / AWS

Why This Role?

Take technical ownership of complex cloud solutions across customer opportunities, bids and live delivery engagements. You'll shape secure, scalable and commercially viable Azure and AWS solutions, taking them from early-stage architecture through to delivery assurance.

This is a highly customer-facing role where you'll influence technical direction, solve complex architecture challenges and help turn ambitious cloud transformation requirements into solutions that engineering teams can successfully deliver.

What You'll Be Doing

• Lead solution architecture across complex cloud migration, modernisation, landing zone, platform, security and cloud-native engagements.
• Shape technical solutions for customer opportunities, bids and RFPs, balancing technical quality, commercial viability and delivery practicality.
• Design secure, scalable and resilient solutions across Azure and/or AWS, spanning infrastructure, networking, identity, governance and operations.
• Produce and assure architecture artefacts including HLDs, LLDs, reference architectures, design documentation and architectural decisions.
• Lead customer discovery sessions, technical workshops, design reviews and solution playback sessions.
• Work closely with Cloud Engineering and Delivery teams to ensure architecture is practical, implementable and operationally sound.
• Provide architecture governance and design assurance, identifying risks, dependencies, constraints and exceptions before they impact delivery.
• Maintain alignment between the solution developed during presales and what is ultimately delivered.
• Contribute to cloud architecture standards, reusable patterns, blueprints and reference designs.
• Mentor Cloud Solutions Architects and help strengthen architecture capability and best practice across the wider team.

What We're Looking For

Essential

• Deep expertise in Microsoft Azure and/or AWS within complex enterprise cloud environments.
• Strong cloud architecture knowledge across IaaS, PaaS, SaaS, networking, identity, security, governance and operations.
• Experience designing cloud migration, modernisation, landing zone, platform or cloud-native solutions.
• Proven experience leading complex solution architecture and producing implementation-ready architecture documentation.
• Good understanding of DevOps, Infrastructure as Code, automation and platform engineering principles.
• Experience contributing to or leading bids, RFPs, proposals and customer solution development.
• Strong understanding of architecture governance, technical assurance and design decision-making.
• Ability to confidently lead technical discussions with both technical and non-technical customer stakeholders.
• Ability to balance customer requirements, technical quality, delivery risk and commercial considerations.

Desirable

• Experience across both Azure and AWS.
• Microsoft Azure Solutions Architect Expert (AZ-305) or equivalent practical experience.
• AWS Certified Solutions Architect - Professional or equivalent practical experience.
• TOGAF or another recognised architecture framework/certification.
• Experience with FinOps, cloud governance, cloud security and operational readiness.
• Experience mentoring architects or other technical professionals.
• Public speaking, technical thought leadership or knowledge-sharing experience.

The corresponding role documentation likewise treats Azure/AWS, enterprise-scale cloud delivery and architecture experience as central, with TOGAF, security, FinOps and cloud-governance credentials adding value.

Why This Opportunity Stands Out

You'll work across the full architecture lifecycle rather than being limited to either presales or delivery. That means shaping solutions during customer engagements, influencing bids and RFPs, establishing architectural direction and then helping ensure the resulting solution remains technically sound through delivery.

You'll also have scope to influence reusable architecture patterns and standards, mentor other architects and work across areas including cloud migration, modernisation, cloud-native architecture, landing zones, platform engineering, security, governance and FinOps
