Solutions Architect

We are seeking a seasoned Senior Solution Architect to lead a critical legacy app modernisation program of work for a major enterprise client.

Embedded within the Enterprise PMO Delivery Portfolio, your primary focus will be architecting the next-generation customer-facing digital portal. You will bridge legacy systems with cutting-edge cloud infrastructure-ensuring the new portal is secure, highly scalable, and delivers exceptional user outcomes.

Key Responsibilities

• Lead the architectural design and decomposition strategy to modernise monolithic legacy applications into microservices and modern cloud-native architectures.
• Define the vision, integration patterns, and target-state architecture for a high-traffic, customer-facing portal focused on security, performance, and seamless user experience.
• Serve as the subject matter expert for AWS cloud design, establishing best practices for serverless, containerisation, API gateways, and cloud networking.
• Evaluate legacy constraints, formulate technical options (RFIs, RFPs, or PoCs), and define phased, risk-mitigated migration roadmaps.
• Collaborate closely with Enterprise Architects, product leads, and third-party vendors to align business vision with technical execution.
• Architect for high availability, robust Identity & Access Management (IAM), observability, and strict compliance in a regulated environment.

Key Challenges in the Role

• Architecting a seamless customer portal experience while untangling and integrating complex, tightly coupled legacy backends.
• Managing phased migration strategies to ensure zero disruption to live customer transactions and ongoing operations.
• Navigating multi-stakeholder expectations across business, security, and IT groups during significant digital change.

What You'll Bring to the Team

• 7+ years in IT, with 4+ years as a Solution Architect driving major enterprise modernisation initiatives.
• Deep, hands-on architectural experience with AWS services (EC2, Lambda, ECS/EKS, API Gateway, CloudFront, S3, IAM, DynamoDB/RDS).
• Proven track record architecting secure, high-availability web portals, mobile APIs, or digital front-ends.
• Experience with modern architecture patterns (microservices, event-driven, API-first design, Strangler Fig pattern).
• Exposure to Snowflake, Java applications, identity providers (OAuth/OIDC), and modern observability platforms (Datadog/Dynatrace) is highly regarded.
• Background in regulated environments, automated CI/CD pipelines, DevSecOps, and cost optimisation (FinOps).
• Exceptional ability to explain complex technical trade-offs to business stakeholders and guide engineering teams through implementation.
