- Leading pre-sales engagements, formal bid responses including proposing solutions and undertaking commercial estimations.
- Designing integrations between AWS environments, other cloud providers, legacy on-premises systems, and third-party services using API-led design, gateways, and BFF patterns.
- Designing distributed, zero-trust architectures using AWS services such as EKS, Lambda, and EventBridge or SNS/SQS to support microservices and event-driven systems.
- Leading cross-functional technical teams in agile deliveries with modern engineering practices (e.g., SAFe and DevOps).
- Applying recognised architecture frameworks and methodologies (e.g., TOGAF, Zachman, Domain-Driven Design, or NIST).
While not mandatory, experience in the following areas is beneficial:
- Senior or managerial-level consulting experience.
- Holding professional AWS certifications such as Certified Solutions Architect and relevant architecture qualifications (e.g., TOGAF).
- Designing enterprise-scale data and AI platforms using AWS-native services such as Redshift, SageMaker, Bedrock, and generative AI capabilities.
