AWS Integration Architect

Own the end-to-end architecture and design decisions for real-time, secure, and performant data flows between AWS, Salesforce, and Dynamics 365 F&O. This is a design-and-leadership role: the architect sets the integration patterns, standards, and performance targets, and leads a small development team to build against them. AWS experience is the key requirement for this contract.

What you'll do:

• Design serverless, event-driven integration patterns on AWS (Lambda, SQS, SNS, EventBridge, Step Functions)
• Make the architecture-level calls on Salesforce integration (REST/SOAP, Platform Events, Bulk API, Salesforce Connect) and on D365 F&O (Data Management framework, OData, Custom Services, Dual-write, Azure Service Bus)
• Define the non-functional requirements and hold integrations to them
• Set the security, compliance, fault-tolerance and observability standards across all three platforms
• Translate business requirements into technical design, and explain the decisions to technical and non-technical stakeholders alike

What we're looking for

• 10+ years in integration and solution architecture
• A track record of design decisions for serverless, event-driven architectures, and the ability to enforce performance and resilience standards across a multi-system landscape
• Strong architectural knowledge of the Salesforce integration surface (REST, SOAP, Bulk, Platform Events, Salesforce Connect) and of D365 F&O integration (DMF, OData, Custom Services)
• A solid grasp of OAuth 2.0, IAM, VPC design and secrets management, plus experience setting data privacy standards across integrated systems
• Experience leading or mentoring a small dev team, and owning the artefacts, HLD/LLD, decision records, integration designs, in enterprise client delivery

This role falls inside IR35, and the candidate must be willing to travel to Central London offices once per week if/when required.
